GSA’s Cospas-Sarsat Meeting Addresses Progress of Search and Rescue Systems

The Cospas-Sarsat MEOSAR (Medium-Altitude Earth Orbit Search and Rescue) system has been in the news quite a bit of late, and with good reason. As the technology has evolved, so too has the ability to improve search and rescue operations which save lives.

The cover story for the current issue of Inside GNSS is dedicated to the Cospas-Sarsat MEOSAR system and its role as a solution to support the ICAO GADSS Autonomous Distress Tracking recommendation.

FAA Now Has Improved GPS Coverage Across U.S. as GEO 5 joins WAAS

The Federal Aviation Administration’s Geosynchronous Earth Orbiting 5 Wide Area Augmentation System (WAAS) navigation payload, developed by Raytheon’s Intelligence, Information and Services business, is now operational and fully integrated into the WAAS network. The GEO 5 payload joins two others already on orbit in correcting GPS satellite signal ionospheric disturbances, timing issues, and minor orbit adjustments, giving users increased coverage, improved accuracy, and better reliability.

GPS IIIF: The Air Force Decides to Stick With Lockheed

Over at least half a dozen years the GPS III Follow On program has taken a number of dramatic turns only to wind up, in true soap opera fashion, with the same leading characters headed to the altar.

At the end of the latest episode, the field of suitors for the multi-billion-dollar GPS IIIF contract narrowed suddenly in April when two of the three corporate hopefuls abruptly left the field.

Letter About Ligado in Limbo

The issue at hand is whether the Federal Communications Commission (FCC) should allow a change in the use of frequencies close to those used by GPS. Virginia-based Ligado Networks wants to repurpose its satellite frequencies to also support ground-based telecom services. Testing done several years ago and expanded upon more recently has shown such a system could seriously interfere with GPS receivers.

Some three months after a meeting of the key federal agencies using and running the GPS program, they have yet to release a letter stating their recommendation on whether to allow the development of a potentially interfering telecommunication service.

The Cospas-Sarsat MEOSAR System: A Solution to Support ICAO GADSS Autonomous Distress Tracking Recommendation

Today, it appears that the Cospas-Sarsat MEOSAR system, relying on payloads deployed on GNSS constellations (Galileo, GPS, GLONASS), offers all the conditions to meet the new recommendation of ICAO for ADT-system for Commercial Aviation, with a new generation of in-flight triggered beacons, identical to the current ELT in terms of aircraft integration, but capable of receiving triggers and cancellation events from the avionics, from the crew or from internal sensors, and of detecting and managing their inhibitions to maintain the capability to raise alerts and be localized in any situation.

GAO: GPS Modernization Costs Remain Unclear

A new watchdog report says the Air Force has yet to develop full cost estimates for the new ground system and user equipment essential for utilizing the expanded capabilities of the upcoming GPS III generation of satellites.

The Government Accountably Office (GAO) said in its annual assessment of weapons systems for Congress that the Air Force is still developing a final budget number and schedule for the Next Generation Operational Control System (OCX). OCX is necessary for implementing the new military M-code among other enhancements.
