Upgrades to monitoring stations support EGNOS

May 29, 2017By

Upgrades to the monitoring stations underpinning Europe’s EGNOS satnav augmentation system will support its evolution, said the European Space Agency. The current 40 Ranging and Integrity Monitoring Stations (RIMS) sites across Europe and beyond are the bedrock of the European Geostationary Navigation Overlay Service (EGNOS), supplying highly accurate and robust satnav information that can be relied on for safety-critical purposes.... read more

Raytheon launches WAAS payload to improve GPS accuracy for air travel

May 22, 2017By

Raytheon Company has launched its GEO 6 satellite payload into orbit for its 12-year mission. It is the latest payload to support the Federal Aviation Administration’s (FAA) Wide Area Augmentation System (WAAS), which enhances the reliability and accuracy of GPS signals for directing air travel. The Raytheon-developed payload is a key element of WAAS, which offers commercial, business and general aviation... read more

Congress increases funding for UAS research, airspace integration

May 11, 2017By

More than $20 million for research on unmanned aircraft systems (UAS) was included in an appropriations package that Congress passed and the president signed into law last week to fund the federal government through the end of the fiscal year on Sept. 30. The funding for UAS research is $2.67 million more than last year’s budget request by the Federal... read more

UAV testing facility selects Harris for BVLOS support

May 11, 2017By

Grand Sky Airfield Operations, a 217-acre UAS test facility in North Dakota, has selected Harris Corporation to provide an advanced solution to support beyond-visual-line-of-sight (BVLOS) unmanned aerial systems (UAS) flight operations, reducing the need for chase planes to provide constant visual surveillance during flight. Grand Sky tenants will have the ability to conduct BVLOS UAS flights, enabling commercial and government... read more

GSA contracts with Eutelsat on next-gen EGNOS payload

March 29, 2017By

The European Global Navigation Satellite Systems Agency (GSA) has selected Eutelsat Communications for the development, integration and operation of the next-generation EGNOS payload on a future Eutelsat satellite. Eutelsat and GSA have concluded a long-term contract valued at €102 million covering the preparation and service provision phases for the EGNOS GEO-3 payload that will be hosted on the Eutelsat 5... read more

Sensor role reversal: How lidar can replace GNSS for navigation

Airborne lidar/INS/GNSS: Algorithm Uses Fuzzy Controlled Scale Invariant Feature Transform Sensor role reversal: Lidar with its superior performance can replace GNSS in the integration solution by providing fixes for the drifting inertial measurement unit (IMU). Tests show its potential for terrain-referenced navigation due to its high accuracy, resolution, update rate and anti-jamming abilities. A novel algorithm uses scanning lidar ranging... read more

Geoscience Australia, Lockheed collaborate on multi-GNSS SBAS research

February 13, 2017By

Geoscience Australia, an agency of the Commonwealth of Australia, and Lockheed Martin have entered into a collaborative research project to show how augmenting signals from multiple GNSS constellations can enhance positioning, navigation and timing for a range of applications. Other partners are Inmarsat and GMV. The research project aims to demonstrate how a second-generation Satellite-Based Augmentation System (SBAS) testbed can... read more

Tracking RFI: Interference localization using a CRPA

A controlled radiation-pattern antenna can preserve GNSS positioning while providing at least an azimuth angle towards an interference source. If integrated with an attitude and heading reference system, only a few lines of position pointing towards the RFI source could provide a fast indication of the probable ground location. read more
