Really Rocket Science

Qualcomm is teaming up with SkyTerra’s Mobile Satellite Ventures (MSV) and ICO Global Communications to integrate satellite communications into mass-market cellular handsets, Wireless Week reports:

Under the agreement, Qualcomm will integrate satellite and cellular communication technology by developing a satellite protocol and including it in the firmware of select Qualcomm multimode baseband chips.  Qualcomm also plans to support the L- and S-Band frequencies, in which MSV and ICO operate, in select RF processors.

In essence, the same mobile chipsets at the heart of wireless devices will let handset makers produce satellite-capable devices at comparable scale and cost.

I guess this might mean the end of the "can you hear me now?" commercials, eh?

The quality of the players in this venture (no pun intended) bode well for its ultimate outcome. Qualcomm developed its satellite-based asset-tracking service, OmniTRACS, years before GPS technology became commercially available. OmniTRACS  is what’s inside those little white domes you see on on Sears trucks.

Here’s a video of how it works: 

Qualcomm is also working on the Google Android phone, which is supported by the Android open-source operating system and intended as a major competitor to the Apple iPhone:

Qualcomm is likely to face stiff competition in the future from chipmakers who want in on the Android action. 

Perhaps we’ll see similar functionality as what’s found in the Thuraya system, with the Android switching between GSM and satellite as required?

Time will tell.

The Shenzhou VII spacecraft will blast off tomorrow with three astronauts aboard, one of whom will be the first Chinese to walk in space:

The taikonauts, as they are known in the mainland, will be equipped with space-age gadgets as well as down- to-earth pencils.

Responding to the challenge experienced by international experts in producing a writing instrument that works in no-gravity conditions, mainland scientists came up with the common lead pencil. Thicker than the earth variety, China’s space pencil has a special carbon compound.

Shenzhou VII will release a small satellite to monitor the operation of the spacecraft itself and the progress of the spacewalk. During the mission, new satellite communications technology will be tried out as well.

China is using five satellite tracking ships to monitor the mission. They’re now in place:

The final Yuanwang ship arrived at its destination on Monday, said Jian Shilong, director with the China Maritime Tracking and Control Department.

The ships will remotely track and support the Shenzhou VII space shuttle which will blast off in late September.

Four ships are on the Pacific ocean and one is on the Atlantic.

"In previous missions including the Shenzhou V and Shenzhou VI missions, only four tracking ships were deployed," Jian said. "We added one more to the Shenzhou VII mission to monitor the taikonaut’s extra-vehicular activities."

Jian said the tracking ships will monitor the entire space walk and also keep tabs on the depressurization of the orbital module when taikonauts leave and re-enter the spaceship.

The Yuanwang ships can control the shuttle’s solar panels, its orbit maneuvers and maintenance.

 In all, China boasts a fleet of six Yuanwang space tracking ships which have carried out 68 expeditions and traveled more than1.4 million sea miles in the Pacific, Atlantic and Indian oceans.

The tracking ships, combined with 20 terrestrial surveying stations, constitute China’s space telemetry network.

Why the extra ship? Because the planned space walk is a big deal in Chinese popular culture — presenting an unprecedented [communications] challenge for the Chinese, who want to provide seamless, high-quality live video feeds of the outing.

A space industry source explains:

The source said China had proved to the world it could maintain long-distance communication with its lunar project, but stable broadband communication had always been a barrier for Chinese technology. The deficiency meant China was still unable to compete with the US and Russia in the civilian commercial communication satellite markets.

But in the past couple of years, China had achieved several breakthroughs in antennas that were used for rapid communication with the Earth, and the space walk "will be a window to show how much China has caught up in this highly important field", the source said.

Because the antenna was directional and must be pointed to a small target area, the source said the astronaut would probably emerge from the spacecraft while orbiting over China, to enable the Chinese people to witness the event.

 And what will they do on the spacewalk? Nothing much, really:

When asked about what the astronaut will actually do outside the spacecraft Qi said he once suggested retrieving the national flag that hangs outside the spaceship. After consideration it was finally decided the astronaut would perform some test and control experiments. He added, "Whether it’s fetching the national flag or doing some experiments, the astronaut will have to do something, so that it’s not just a case of proving our ability to put someone outside the spaceship."

In Europe, there’s been a huge coordinated effort by scientists to monitor the state of the environment through the Global Monitoring for Environment and Security program, or GMES for short.

Of course, GMES is a bit of a tongue twister, which is why GMES now has a new name: Kopernikus, named, of course, after the Polish astronomer.

Their motto is "We care for a safer world."  Involving projects in numerous countries around the world, the objective of Kopernikus is to monitor the state of the environment on land, at sea and in the atmosphere and to improve the security of the citizens in a world facing an increased risk of natural and other disasters.

The ESA provides additional information:

More than 40 European and non-European Earth Observation satellites have united to provide data to GMES Services over the next years. ESA will coordinate the data acquisitions seeking to optimise resources from the variety of European and non-European EO satellite missions. Considered missions include ESA Member States’ missions, such as France’s Spot and Pleiades satellites, Germany’s TerraSAR-X, Italy’s CosmoSkyMed, the UK-led DMC constellation (including the soon-to-be launched DMC-UK2 and Spain’s Deimos-1), as well as Canada’s Radarsat, Israel’s Eros and other non-European missions distributed through European companies. In addition, ESA will act as data provider for its own EO missions, such as Envisat and ERS-2, as well as its Third Party Missions.

Here’s a great video of how the birds give scientists a nice view of the earth:

The 49th state has been in the news lately, but we heard from the 50th state yesterday when Sen. Daniel Inouye raised the alarm that the next president could be a victim of the current administration’s handling of the digital TV transition:

“I am troubled that a bipartisan and noncontroversial public policy goal, intended to help our emergency first responders better serve and protect the American people, may end up as an albatross around the neck of our next president,” Inouye said.

The House will hold a hearing tomorrow morning on the status of the DTV transmission; the Senate will hold one next week.

This group of potential tube casualties includes a disproportionately large portion of Spanish-speaking, elderly and low-income Americans. Of the 21 million US households that rely exclusively on over-the-air television, the GAO found that almost half had incomes under $30,000 and that about 28 percent of them were Hispanic.

In advance of today’s House Commerce Committee "DTV Transition" hearing, the Consumer Electronics Association released new research findings.

According to their market research, consumer awareness of the digital-TV transition is now at 86%, up 12 percentage points from the beginning of the year. 32% of households with at least one analog-only over-the-air TV have applied for converter boxes, while another 37% know they will have to and plan to do so by year’s end. That adds up to 14 million converter boxes, the CEA said, for which the National Telecommunications and Information Administration should have enough coupons to cover.

Meanwhile, Wilmington, North Carolina last week became the first city in the U.S. to make the all digital transition, well ahead of next year’s February 17th deadline.

Those of you who may be working on the digital transition might want to follow this great blog on Wilmington’s transition, to gain a little advance insight into the stumbles and successes that Wilmington is facing with its residents in the immediate aftermath of the transition.

Local station WECT has also put up an informational page on their site, which will probably be held up as a good example for other stations to follow.

We can’t say that the "DTV Answers Booth" in Wilmington, pictured above, was overwhelmed by the curious, however.

Broadcasters certainly have their work cut out for them as the transition approaches, with lots of educating to do. Here’s a PDF from the FCC site featuring an analysis of calls from the second day of the Wilmington transition.

You may have heard about OnStar’s anti-theft device:

What happens is this — if you report your car as stolen, you can then call OnStar and have them work with law enforcement to use the car’s GPS system to find where your vehicle’s located. OnStar will then have the police make visual contact with your vehicle and once they’ve determined it’s safe to do it, will shut down the drivers ability to manually control acceleration. Basically, they shut down the accelerator, causing the vehicle to coast to an idle speed — but not causing the driver to lose steering or braking control. At the point in which the vehicle comes to a stop (or close to it — idle speed) — the police can then apprehend the "perp.

For those of you without OnStar, there are stand-alone alternatives, such as LoJack and Inilex. While neither of these will physically slow down a vehicle (think how different the OJ chase scene would have been if OnStar had been around then!), they can be used effectively for theft recovery.

But here’s the Catch-22. With the economy in a slowdown, crime is up. But with the economy in a slowdown, your cash is down. 

What do do? DIY.

The DIY SPY has a "Retro GPS tracker which, when combined with their tracking software, can be used to determine where a vehicle has travelled. Unfortunately, it appears you have to retrieve the unit to download the data, which makes it less than ideal for recovering stolen vehicles, but not a bad item to have in any modern PI’s bag of tricks.

If you want to go even cheaper, you can build your own "Ghetto Lojack" for $30 by picking up a cheap boost mobile phone at Target and combining it with the Mologogo website, which we first blogged about here.

If you’ve got the dough, and the REI outfit to match it, you could always get a SPOT personal locator beacon (with their great slogan: "live to tell about it") for $170.

Did you see it?

The brightest explosion ever seen was observed in March this year, Physorg.com reports. Now a team of astronomers from around the world have combined their data from satellites and observatories to explain what happened.

What they saw — and indeed, it was visible to the naked human eye — was a Gamma-Ray Burst (GRB) aimed directly at our solar system.

A Gamma Ray Burst is not to be confused with Gamera:

GRBs are bright — but they are easy to miss.  NASA explains:

Like galactic fireworks in the night, gamma-ray bursts briefly light up the stellar sky as only the most powerful explosions in the universe can. Yet as magnificent as gamma-ray bursts are, their fleeting nature makes them elusive and difficult to study….

Gamma-ray bursts are incredibly intense releases of gamma radiation. Found at the highest frequency end of the electromagnetic spectrum, gamma radiation is a particularly energetic form of light that can only be generated by the most powerful astronomical events. Scientists suspect that these sporadic explosions may signal the birth of black holes or the death of stars.

The first gamma-ray bursts were detected in 1967 by the U.S. military’s Vela satellites. This fleet of satellites was originally designed to monitor nuclear weapons testing and could sense large releases of gamma radiation. While orbiting the Earth, a Vela satellite recorded a burst of concentrated gamma energy from deep space. For the first time, a gamma-ray burst was observed by humans.

So how was the GRB captured back in March? A bit of luck, combined with teamwork:

GRBs are the Universe’s most luminous explosions. Early in the morning of March 19, the Swift satellite, a joint NASA/UK/Italian mission, pinpointed an extremely bright GRB and immediately sent out an alert to observatories around the world. Two robotic wide-field optical cameras in Chile also observed the brief flash: "Pi of the Sky," which is operated by the Centre for Theoretical Physics in Warsaw, Poland, and TORTORA, based at ESO’s La Silla Observatory. TORTORA is operated by a Russian-Italian collaboration. Within minutes many more telescopes were observing, allowing for the most detailed study of a bright GRB ever undertaken using data from gamma-ray to radio wavelengths.

Remember all those AOL CDs that used to clutter up your mail box, and served as great drink coaster during your austere grad school days?

We haven’t seen them as often in our mailbox as we used to, but we still have a pretty good collection of old software CDs, misburned DVDs, and some really embarrassing music CDs that are best left unmentioned.

What to do with them all? We observed just the other day that it’s getting darker earlier, and we may soon be needing some additional light in the Really Rocket Science lair.

And thus we arrive at today’s DIY Friday project: build your own CD stack lamp!

 The project is relatively simple:

 The pile of CDs that had been massing in my room was growing to epic proportions. So I decided to make myself a CD lamp. The circular base was actually cut using a template on a table saw, then sanded after clamping it in a drill press. The cold cathode lamp is from NewEgg….

There are several other designs online, but this is one of the better ones that I have found.

Check out the additional photos here.  When completed, the lamp also serves as a rather luminous shrine to duct tape.

There’s little doubt that GPS has made the world a better place. The combination of satellite technology and an old fashioned map has kept a lot of people — yours truly included — from getting stupidly lost. It’s also made waiting for the bus a far less mysterious endeavor.

Increasingly, too, when people do stupid– and criminal– things, GPS is helping to unravel those mysteries, too.

The AP reports on how the proliferation of GPS is being used in forensics:

The growing popularity of GPS systems — in cars, cell phones and other handheld devices — gives authorities another powerful tool to track suspects.

Among recent cases:

_ In September, a man in Butte, Mont., pleaded guilty to rape shortly after a judge ruled that evidence from the GPS unit in his car could be used against him at trial. Prosecutors planned to use it to show that Brian D. Adolf "prowled" through town looking for a victim.

_ In New Brighton, Pa., a trucker’s GPS system led police to charge him with setting his own home on fire. GPS records showed his rig was parked about 100 yards from his house at the time of the fire.

_ In the case of a missing Chicago-area woman named Stacy Peterson, investigators sought GPS records from the SUV owned by her husband, former police officer Drew Peterson. She still hasn’t been found, and no one has been charged….

 "What we’re dealing with here is a use of the technology that I don’t think the good people at Magellan or Garmin or TomTom really thought about when they were developing it," says one police detective:

Detectives are often able to extract map searches and desired destinations that have been entered into a GPS unit by the user. Some devices are equipped with a "track back" feature that can show where the unit was at a particular time….

The GPS feature on a cell phone has already helped solve at least one crime. In 2006, police in Virginia Beach, Va., used the GPS on a homicide victim’s cell phone to find the phone and her purse in a garbage can behind a home. The home was linked to the man who was eventually charged with killing her.

Jon Price, a trainer at Garmin Ltd., the leading maker of commercial GPS units in the U.S., started getting calls five years ago to work with law enforcement in cases involving GPS data from the company’s units was being used as evidence.

Price estimates he’s helped with about 25 criminal cases, some of them involving GPS-equipped boats running drugs out of South America. He’s testified as an expert witness in a half-dozen cases…

"Typically the GPS data being used is for the purpose of contradicting (defendants’) alibis," Price said.

GPS data is usually just one part of the criminal case, however, as attorneys must also prove the defendant possessed the unit and entered the information into it. 

Seven weeks ago, Eutelsat’s W5 craft suffered a major technical failure, resulting in Eutelsat having to shut down four transponders. They lost a number of channels, including controversial Chinese channel New Tang Dynasty (NTDTV). 

That’s one side of the story.

The other side of the story goes like this:

Because New York-based NTDTV is sympathetic to the banned Falun Gong organisation and is one of the few critical voices going into China, NTDTV has blamed Eutelsat for attempting to cosy up to China in order to win more Chinese business. (Muddying the waters was the admission by a Eutelsat staffer in China that the channel had been taken off the air because of political pressure.)

Not coincidentally, critics maintain, the loss of NTDTV on Eutelsat came just before the Olympics began in Beijing.

RapidTV has more: 

[0]ver the past seven weeks NTDTV has carried out an impressive press and public relations exercise targeting Eutelsat, and winning support from international but largely ill-informed press organisations such as Reporters Without Borders and other independent NGOs. The pressure is continuing. Last week NTDTV participated in a Forum in Sydney, Australia and which featured speakers arguing for more independent voices going into China.

Adding to the pressure was a statement from the Brussels-based International Federation of Journalists arguing for Eutelsat to “stop hiding behind the technical mumbo-jumbo” and to reinstate the signal. The European Union has also written to Eutelsat asking for an explanation.

Eutelsat, in a measured response, has repeated that it holds “absolutely no prejudice against channels broadcast by our satellites and notably NTDTV which continues to broadcast in Europe” via Eutelsat’s Hot Bird system, says Eutelsat. “NTDTV has been treated in every respect in identical fashion to other channels present on the W5 capacity that had to be shut down.  The loss of the use of one of the satellite’s solar panels, requiring the immediate shutdown of four transponders used principally for Direct-to-Home television broadcasting which consumes most power, resulted in a loss of signal over Asia for EuroNews and C-Music as well as NTDTV.”

Eutelsat also responded to reports that capacity on W5 has magically become freshly available since the incident with the termination of broadcasts by Radio Free Asia and Voice of America. “These services were broadcast within the framework of a contract with the American broadcaster IBB. The termination of this contract, which Eutelsat was aware of before the W5 incident happened, was naturally taken into account in managing the consequences of the satellite’s power loss. The end of the IBB contract provides us with margin which is required to continue operating W5 in orbit in a safe condition, but it does not make it possible for us to restore any DTH broadcasting service, either for NTDTV or any other TV channel.”

Eutelsat’s statement continued: “The extent of the problem affecting W5 was explained in person to NTDTV when we received Mr Wang, President of NTD TV Canada, at our headquarters in Paris on 6 August. We confirmed to him that the technical anomaly is irreversible as the technical review completed with Thales Alenia Space (the satellite’s manufacturer) has concluded that there has been a 50% reduction of the satellite’s power following permanent loss of the use of one of the satellite’s two solar arrays.  We also confirmed to Mr Wang that Eutelsat operates no other satellite with coverage of Asia but that there are many satellites operated by other operators that do have capacity available and that are even able to offer superior coverage of China than W5.

Jean-Paul Brillaud, Eutelsat’s deputy CEO, stressed in an interview with Agence France Presse, that the [technical] breakdown is irreversible, and that NTDTV had not considered alternative transmission solutions suggested by Eutelsat.

With the US analog switch-off date — the Analog Deathwatch, as we like to call it — mandated for February 2009, and most Western European countries terminating transmission before the European 2012 Analog Deathwatch deadline, the next 2 years will see a rapid increase in new digital TV households.

Just how much of an increase? A new report from market analysis firm Datamonitor has the details:

DTV will grow an average of 12% year-on-year, with particularly strong adoption in the near term as broadcasters terminate analog terrestrial television," says Chris Khouri, analyst for media and broadcasting at Datamonitor and the report’s author."In 2007 there were 158 million households using digital television services in Western Europe and the US. By 2012, Datamonitor expects there to be an estimated 274 million digital TV households in these regions."

At the end of 2007, 54% of homes in Europe and the US had some form of DTV service. This will grow to 88% by the end of 2012 primarily due to the significant increase in digital terrestrial television (DTT) households, according to the report:

DTT households in Europe and the US will increase from 26 million in 2007 to 55 million by 2012, illustrating an average yearly growth rate of 16%. As a whole, however, Datamonitor expects there to be a significant migration away from free-to-air services in the medium-to-long term, as bundled offerings (triple play, quad play etc.), enhanced features and premium content grow in importance to consumers.

Digital cable and DTT platforms will experience the largest net additions from 2007 to 2012 Over the next three years, all DTV platforms will show strong growth as consumers transition to digital services. The two fastest growing platforms in Europe and the US will be digital cable and DTT. Datamonitor expects they will achieve net household increases of 50 million and 30 million, respectively.

And here’s the bit that stokes two of our greatest obsessions — satcom and IPTV:

PTV services will show the strongest average yearly growth at around 28%, reaching almost 23 million households by 2012.

Despite satellite services illustrating very moderate growth of 5.5%, there will be a 20 million increase in subscribers by 2012, reaching around 86 million households.

The boom years lie ahead, that’s for sure.
