Interesting, and if the point about Garmin is true, what is the relationship between them and the Air Force? The Air Force has gotten into a lot of areas that include tracking to the individual level (RFI) under the guise of tracking logistics….
Following a navigation system's instructions without driving into a ravine is hard enough as it is — can you even imagine how hard it'd be if you kept losing GPS reception every time you drove within range of an LTE tower? There have been a few anecdotal concerns raised over the last several weeks that LightSquared's proposed LTE network — which would repurpose L-band spectrum formerly used for satellite — is too close to the spectrum used by the Global Positioning System, leading to unintentional jamming when the towers overpower the much weaker GPS signals. Things have gotten a little more interesting, though, now that the US Air Force Space Command has officially piped in. General William Shelton has gone on record saying that “a leading GPS receiver manufacturer just … has concluded that within 3 to 5 miles on the ground and within about 12 miles in the air GPS is jammed by those towers,” calling the situation “unbelievable” and saying he's “hopeful the FCC does the right thing.”
Phi Beta Iota: Electromagnetic conflicts have been a known issue since the 1980's. The Soviets had emission control standards ten times tougher than the US, which had (and continues to have) virtually no standards at all. This is one reason why US forces in Afghanistan are so severely hampered, with drones, aircraft, radars, and various other “systems” all interfering with one another. Elsewhere, notably in England, modern cars come to a complete stop within a couple of kilometers of certain Royal Air Force emitting stations. All of this can be attributed to at least four root problems:
1. An acquisition archipelago (nothing sytematic about it) so stupid and out of control as to defy belief. No standards, no brains, no integrity.
2. Service-centric and mission-centric “preferred contractor” and “proprietary single point solutions” standard operating processes that are deliberately not orchestrated with other services, civilian elements of the government, or other nations.
3. A lack of integrity among senior officers who should know better.
4. A lack of integrity in Congress, where the focus is on collecting the 5% kick-back from delivered programs, not on actually serving the public interest by insuring affordability, interoperability, sustainability, and utility.
