Features

Tron 40GPS has been designed to operate with the COSPAS-SARSAT system. The Tron 40GPS is also meant to enhance further the lifesaving capabilities of conventional beacons. The integrated 12 channel GPS module accepts continuous positional information from the standard Global Positioning System using 27 satellites providing an accuracy of approximately 100m. Upon activation of the Tron 40 GPS in an emergency situation the positional information is incorporated into the distress message transmitted by the Tron 40 GPS.
The main advantage with integrated GPS in Tron 40 EPIRB is the rapid response and positional accuracy providing vital information during a rescue operation practically eliminating valuable time spent searching for the distressed. Whenever a distress message transmitted by Tron 40GPS is detected by a polar orbiting satellite (LEOSAR) the delayed alert remains the same as for non-GPS integrated EPIRBs (max 90 min.), but the positional accuracy is improved considerably from a radius of 5km to an amazing 100m. Upon detection of a distress message transmitted by Tron 40GPS made by a geostationary satellite (GEOSAR) the improvement of intergrated GPS proves its benefit as the alert is immediate (max 5 min.), still providing the accurate position of 100m.

In addition to the obvious improved lifesaving benefits for all users, from private yachts to large passenger vessels, the Tron 40GPS offers also increased safety for vessels carrying hazardous cargo making detection and location of any emergency situation or accident more rapid and accurate, preventing crucial time wasted whenever the consequence of the accident may represent a danger or threat to the environment.

Please note that the positional accuracy and alert delay is dependent on the actual protocol used and programmed into the EPIRB and the location of the emergency. The information is based on the capacity of the LEOSAR/GEOSAR COSPAS-SARSAT system.
