Novatel Launches Multi-GNSS Wideband Antenna

NovAtel Inc. today (April 23, 2015) launched the GPS-704-WB antenna, a wideband antenna that supports L-band as well as the frequencies of all current GNSS constellations (GPS, GLONASS, Galileo, and BeiDou), including B3 and E6 signals. Customers can use this antenna for GPS-only or multi-constellation applications, providing excellent flexibility for application developers, according to the company.

GNSS Markets, Standards, and Resilience at the European Navigation Conference

The 2015 edition of the European Navigation Conference (ENC) in Bordeaux last week found the continent’s GNSS community leaving troubles behind and looking to the future, where the world’s dependence on GNSS is greater, the risks higher, and the potential profits ever more tantalizing.
 
Speaking at the opening session dedicated to “the impact of GNSS on the economic sector,” Topos Cluster President Florence Ghiron answered the question in the simplest of terms: “We expect the GNSS market to grow and to include more and more industrial sectors.”

Renewed Spectrum Fight Emerges between GPS, LightSquared at ABC Workshop

Spectrum-related tensions reemerged during a workshop on Thursday (March 12, 2015) organized to gather feedback on a testing plan to help protect GPS receivers.

The plan is part of the GPS Adjacent-Band Compatibility (ABC) assessment — a wide-ranging effort to determine the power levels at which services operating in frequencies next those used by GPS and other GNSS systems can broadcast signals without causing interference to GPS signals.

GNSS and Precision Farming

Nowhere has the fact that GNSS can guide things besides military weapons and transport manifested itself more profoundly than in agriculture.

While Google and automotive manufacturers struggle to figure out how to put autonomous vehicles on the highway, farmers have been using GNSS for well over a decade to guide equipment through their fields — along with a host of other ag-related, site-specific applications.

Indeed, GNSS — along with an array of other high-tech resources — is transforming agriculture at an accelerating rate.

How does a GNSS receiver estimate velocity?

Q: How does a GNSS receiver estimate velocity?

A: Stand-alone single-frequency GNSS receivers represent the largest slice of the commercial positioning market. Such receivers operate mainly in single point position (SPP) mode and estimate velocity either by differencing two consecutive positions (i.e., approximating the derivative of user position) or by using Doppler measurements related to user-satellite motion.
