Spirent Test Solutions Help to Improve Maritime Safety

ACR’s ResQLink+ Buoyant Personal Locator Beacon.

Spirent Communications plc this week announced its test solutions have been used to improve maritime safety, and this development came about after much collaborative work designed to ensure that GNSS receivers are performing as needed, especially for rescue operations at sea.

Working with the Radio Technical Committee for Maritime Services (RTCM), Spirent has created test scenarios that simulate realistic satellite reception conditions at sea so that GPS distress beacon performance can be improved, allowing users to be rescued faster by search and rescue organizations.

ESA Inside View on the Present and Future of GNSS

Miguel Mantiega Bautista talks about the ECA’s view on GNSS while attending the Navitec conference in Noordwijk.

The first generation of the Galileo Program, at satellite and ground segment level, has been “an enormous success," according to Miguel Manteiga Bautista, who spoke with Inside GNSS last December at his office at the European Space Agency’s European Space Research and Technology Centre (ESTEC) in Noordwijk.

The U.S. Air Force has approved Lockheed Martin’s current GPS satellite ground control system upgrade to enable it to operate with more powerful and accurate GPS III satellites, the company said.

The Air Force’s Critical Design Review (CDR) for the Contingency Operations (COps) contract, completed on November 17, allows Lockheed Martin to proceed with the modification of the existing Architecture Evolution Plan (AEP) Operational Control Segment. The AEP, maintained by Lockheed Martin, controls the 31 GPS IIR, IIR-M and IIF satellites in orbit.

Two More Galileo Satellites Transmitting Navigation Signals

After months of testing, the European Space Agency (ESA) has announced that Galileo satellites 13 and 14 are transmitting healthy navigation signals and ready to relay distress calls to emergency services.

The satellites, launched from Europe’s Spaceport in French Guiana on May 24, went through lengthy testing that included receiving and uplinking signals through specialized antennas, ESA said. Some of the tests included navigation and search and rescue payloads methodically switched on, the agency said.

NOAA Expands GNSS Data Sources for Weather Prediction

The National Oceanic and Atmospheric Administration (NOAA) will purchase data from small commercial satellites to expand its GNSS radio occultation (RO) efforts to better predict weather.

In September NOAA, through the government’s Commercial Weather Data Pilot program, awarded contracts to San Francisco, California-based Spire Global ($370,000) and GeoOptics ($695,000), of Pasadena, California, to provide RO data. This data will be used to assess whether commercially provided information can be incorporated into the agency’s weather models.
