Honeywell Global Tracking, part of Honeywell's Scanning and Mobility business, is working in partnership with the Aerospace & Defense division of Capgemini, the prime contractor for the Galileo search and rescue program, to deliver a high-precision positioning system that is fully compatible with the international standard, which is known as the Cospas-Sarsat standard. Tests using the Honeywell system have proven that the time from beacon transmission to detection and processing has been reduced from several hours to a few minutes - often the difference between life and death in an emergency situation.
The international Cospas-Sarsat program is a satellite-based search and rescue distress alert detection and information distribution system, best known for detecting and locating emergency beacons activated by aircraft, ships and remotely located people in distress. Honeywell's industry-leading satellite tracking technology, which detects faint alerts sent by emergency beacons around the world using a combination of Doppler curves, noise reduction, and advanced signal processing, quickly calculates the exact location of the beacon and sends the results to the relevant mission control center in the region.
"Up until now, Cospas-Sarsat has relied on satellites in low and high orbits, but medium orbits with satellites such as Galileo are better for search and rescue purposes; they combine a wide field of view with strong Doppler shift, making it more likely a distress signal is pinpointed promptly and accurately," says Fermin Alvarez, ground station and fielding engineer with ESA.
