In November a gathering of 150 GPS engineers convened in Stanford at the Stanford Linear Accelerator Center to discuss the $110 billion GPS market for military and commercial aviation systems, consumer mapping services in cars and automated agricultural machines, among other related industries at the fifth annual Stanford University symposium on Position, Navigation and Time.
A big topic on the table is that GPS is no longer the only navigation and tracking system on the planet any more. According to a November article in Wired, there are four things threatening the future of GPS:
- Next-generation mobile broadband services angling for a piece of the electromagnetic spectrum relied upon by GPS
- Cheap GPS jammers flooding the highways, thanks to consumers worried about invasive police and employers surveillance;
- Cosmic events, like solar storms
- Future location technology that will ultimately push those services to places where GPS hasn’t been able to go.
What’s on the horizon is the new mobile broadband company, Lightsquared, that has been said to threaten GPS signals with interference from a neighboring spectrum. Lightsquared appears at first like it will solve a lot of problems to broadband, by offering cable – like bandwidth to mobile customers through LTE, a next generation wireless service. What’s more, the Obama administration has endorsed Lightsquared – which resides in the same spectrum that runs GPS, which is lower power and gets interference easily.
