RT-400 -- RHOTHETA International Inc
RT-400 is a Radio Direction Finder, which is designed for search and rescue operations (SAR), law enforcement and localizing of radio interference sources. Due to its wideband, the system allows homing to any radio transmitter with a frequency between 118 and 470 MHz inclusively all emergency frequencies such as 121.5, 243 and 406 MHz (COSPAS-SARSAT). The DF system uses a tablet with a compass and GPS. The "DF-Scout" software allows displaying and saving bearing lines on the moving map as well as localizing beacons by triangulation. In case of COSPAS-SARSAT decoding, the beacon position, true bearing and the distance to target are also indicated directly on the map. Homing COSPAS-SARSAT beacons becomes easier when the SAR Scan algorithm is running, which detects the correct COSPAS-SARSAT frequency and scans for 121.5 MHz between C/S pulses. The antenna is mountable on vehicles and can be carried by persons. This allows searching from the vehicle until the terrain becomes impassable and proceeding by foot with the same antenna. Due to the lightweight, comfortable frame and the wireless antenna / tablet communication, the handling becomes very easy. The stable and water protected system can be used at rough outdoor conditions.
