Swift Navigation’s Piksi GPS receiverHaving started out with a crowd source–funded launch through Kickstarter followed by two rounds of more conventional venture capital backing — $2.6 million in 2014 and another $11 million last December — San Francisco, California–based Swift Navigation is going after a low-cost, high-precision market such as unmanned aerial vehicles (UAVs) with its Piksi GPS receiver platform.

The federal government is looking to small firms to help solve some of its toughest GPS-related technology problems with many of the projects focusing on countering jamming while others endeavor to simplify signal acquisition and improve links within the constellation. A recent spate of requests for proposals for Small Business Innovation Research (SBIR) contracts have been released by various agencies. These include the following:

NTSB Chairman Christopher HartOnce again, the National Transportation Safety Board (NTSB) has recommended GPS-aided positive train control (PTC) as one of its “most wanted” transportation safety improvements in 2016. But the agency, which has been advocating for PTC for more than 45 years, appears to be fighting an uphill battle against Congress and the railroad industry.
