NovAtel to Develop WAAS G-III—Galileo Reference Receiver for FAA

October 27, 2015By
NovAtel's WAAS G-III—Galileo Reference Receiver.

The U.S. Federal Aviation Administration (FAA) and NovAtel have exercised a bilateral option to produce a Wide Area Augmentation System (WAAS) G-III—Galileo prototype receiver. Maintaining core NovAtel WAAS G-III functionality for GPS and SBAS signal processing, the new receiver will operate in the WAAS reference station test environment to facilitate research on multiple GNSS constellation utilization. The prototype receiver will also... read more

Let us not exaggerate — nor prematurely announce — the death of a subsystem. However, the demise of the U.S. Nationwide Differential GPS (NDGPS) network can be confidently foretold. Although a Federal Register notice dated Aug. 18 merely seeks public comment on plans to shut down a large portion of NDGPS, the handwriting is on the wall. Once having writ,... read more

Combining Galileo with GPS and GLONASS
While a GPS-based GBAS will offer improved navigation services for aircraft, might these services be even better if the systems were to use satellites from other constellations besides GPS? In this month’s column, the authors show how GBAS protocols might be modified to accommodate multiple constellations, offering results of preliminary tests using GPS, GLONASS, and Galileo simultaneously. read more
