Why LightSquared is more than cronyism … It’s about safety

The recent revelations by Eli Lake at The Daily Beast that a four-star Air Force general was pressured to alter his testimony to favor Light Squared, revealed a new case of cronyism in the White House.  Now a second individual has now come forward to say he too was urged to parrot OMB suggested text in his testimony - that the OMB wants expedited testing for frequency interference.  He refused to do so out of safety concerns.  From The Daily Beast: 
The four-star Air Force general who oversees Air Force Space Command walked into a highly secured room on Capitol Hill a week ago to give a classified briefing to lawmakers and staff, and dropped a surprise. Pressed by members, Gen. William Shelton said the White House tried to pressure him to change his testimony to make it more favorable to a company tied to a large Democratic donor.

The episode —confirmed by The Daily Beast in interviews with administration officials and the chairman of a congressional oversight committee —is the latest in a string of incidents that have given Republicans sudden fodder for questions about whether the Obama administration is politically interfering in routine government matters that affect donors or fundraisers. Already, the FBI and a House committee are investigating a federal loan guarantee to a now failed solar firm called Solyndra that is tied to a large Obama fundraiser.

Now the Pentagon has been raising concerns about a new wireless project by a satellite broadband company in Virginia called LightSquared, whose majority owner is an investment fund run by Democratic donor Philip Falcone.

LightSquared hopes to become a satellite based phone operation similar to land based cell phone service providers.  It seeks to use additional unused frequencies adjacent to the GPS band that currently provide a buffer to GPS service.  Interference from LightSquared satellites could degrade GPS service both for civilian and military users.  The majority owner of LightSquared is hedge fund manager Phil Falcone who between himself and his wife have been heavy contributors to the Democratic Party (over $60,000 last year).

But this meddling is far more than crony capitalism it’s about threatening the integrity and safety of the GPS system.  GPS has grown from its infancy as navigation system to pilot sailboats or to guide you to Aunt Katie’s house in rural Vermont. With accuracy improvements, it can now position anyone consistently within 3 feet, anywhere in the world.  Because of that accuracy it is now being used by aircraft to conduct precision approaches to weathered in airports without ILS.  Down the road air traffic control will become GPS based, rather than ground radar based, as will collision avoidance systems.  In the future GPS will be used to help drive your car autonomously (hands-off or driverless).  Google is currently testing a fleet of autonomously driven Priuses in the Bay area (using backup drivers) and soon will be testing them in Nevada, driverless.  The DARPA Grand Challenge conducted in the 2004 to 2007 period proved that driverless cars can operate safely even in an urban environment.  And farm tractors will soon be doing the same thing.  It is the very accuracy and dependability of this system that will be applied to yet undreamed of applications. 

The administration and the FCC should refrain from reducing safety margins for this irreplaceable system.  The recent case of the North Koreans jamming a US intelligence plane’s GPS navigation system, forcing it to cut short its mission shows that the system is fragile.  We should be working on hardening it, not putting it in jeopardy with risky, self serving actions.

Dueling GPSs

I have been on a trip visiting friends my wife Julie and I have wanted to see, but never had the time. Our previous retirement “vacations” have been to see things or do things. Some of the friends are long lost school mates, friends from the Washington, DC area where we lived for many years, relatives and our dispersed children and their families. It will be an 18 day, 4,700 mile trip by the time we finish next Thursday.

To ensure we arrived where we wanted to go, when we wanted to be there, we equipped ourselves with two GPSs (one a built-in, another, a portable Magellan), as well as Mapquest printouts for each leg. A bit of overkill, but we have been very, very lost on past trips.

The multiple voices guiding us often have given conflicting instructions with one more insistent than the other. Julie named the shrillest Maggie Magellan, but as the trip progressed she became Naggy Maggie. Generally we used Mapquest as the tie breaker, but the calmer sultry voice of the built-in often had me giving preference to her. To counter that, Julie turned the volume down from Naggy Maggie and substituted her own even more sultry voice. Calm, sultry, reassuring female voices always win. In general the Magellan gave the best directions for routes we are familiar with. It, like Mapquest, can be adjusted in advance to follow a preferred route or freeway exits. Possibly there is a way to do it with the built-in (Toyota Prius) but I couldn’t find it. It would give 3 choices (two fastest and the shortest). Estimated Time Enroute also is vastly different for the three systems, with the Prius’s giving the highest time allowance for “pit stops.” The Magellan has been closest to uninterrupted driving time and Mapquest in between, but closer to the Magellan.

As our travels went on, we adjusted to the difference. In one case, the Prius system did not have the ten miles of public roads plotted leading to a community on Albemarle Sound in North Carolina. Fortunately both of the others did. But with freeway driving, it has extremely helpful split screen displays to aid in making the correct turn at the right time. So it is upward and onward with three young ladies guiding me. Life can’t get any better.

Big Brother watching? Coming soon

There is a slow but steady encroachment on our privacy by government. It often comes with rational and admirable cover terms for a hidden agenda. A recent comment by Transportation Secretary Ray LaHood, during his conformation hearings, broached the subject of taxing car mileage based on GPS tracking. An immediate hue and cry went up from privacy organizations which saw it as an Orwellian intrusion. It was dropped like a hot potato by the White House.

The EU is currently looking at another tracking system, again with a lofty purpose, one that will alert other cars to slowdowns and accidents ahead (reducing carbon emissions) called Cooperative Vehicle-Infrastructure Systems (CVIS). It too will be able to track cars anywhere anytime. Rest assured the tracking issue isn’t dead in the US. It will just return at a more opportune time.

The erosion started in the early 1990s, when the US government mandated all new cell phones contain a locating system to help emergency services (911) respond more precisely to cell phone calls. GPS is now almost universally used for this, leaving a trail of phone user's movements. What is little known is these phones can be "pinged" even when turned off, yielding their location. This vulnerability reportedly caused the Hamas leadership in the recent Gaza conflict to ditch their cell phones lest they, like others, find a JDAM down their throats. A recent CIA Director, after several operatives were exposed following a European "rendition" by their cell phones, sent all case officers back to relearn their basic tradecraft. He said they should have realized the only sure way to prevent cell phone tracking is to remove the batteries. Good advice! Even systems we assume serve different purposes like OnStar, include cell phone/GPS technology with all the vulnerabilities.

The increased use of on-street surveillance cameras, far higher powered (intercept friendly, no warrant required) cordless phones (who really needs a 1200 foot range house phone?), and proposed legislation to allow airport security personnel to inspect laptop hard drives for "copyright infringement" is ample evidence of government's insatiable appetite to monitor our private lives.
