The high-precision GNSS industry should expect to see industry consolidation and a scramble for new markets and innovations as prices for high-end chips and modules continue to slide, experts told attendees at a ION GNSS+ panel discussion in Tampa, Florida, last week (September 11, 2014).
The falling prices could strain R&D budgets, they noted, but could also create opportunity as high-end receivers come within reach of emerging industries like self-driving cars, unmanned aerial vehicles, and are even incorporated into consumer products.

Two European proposals to allow pseudolites in the protected frequencies used by GPS and Galileo could soon be adopted, creating a potential interference risk to GNSS receivers and hampering efforts to protect satellite navigation spectrum, experts say.

GPS Networking, headquartered in Pueblo West, Colorado, has announced that it now offers electro-magnetic interference (EMI) shielding on its GPS/GNSS Splitters.
Interference between electronic components is an increasing issue as more wireless components are used to complete broadband systems. Reducing disturbance among separate frequencies through EMI shielding is a critical deliverable for project managers, says Eileen O’Halloran, general manager at GPS Networking

Q: How do measurement errors propagate into GNSS position estimates?
A: Not surprisingly, GNSS positioning accuracy is largely dependent on the level of measurement errors induced by orbital inaccuracies, atmospheric effects, multipath, and noise. This article discusses how, specifically, these errors manifest as position errors.
