The need to accurately pinpoint downed aircraft through the use of a Crash Position Indicator (CPI) or Automatically Deployable Beacon (ADELT) has always existed. The Techtest 503-16 deployable ELT series combines full Cospas/Sarsat coverage together with the transmission of last known GPS co-ordinates to accurately locate downed aircraft. Features include;…
The 13-150 series of antennas offers significally reduced visual profile with electrical performance comparable to passive antennas more than twice the size. These antennas are adaptable to multi band frequency requirements with added UHF functionality already acheived within the same footprint. System OperationThe 13-150 series of antennas utilise advance high…
The 500-30 is a direct upgrade replacement for the URT33 and URT44 beacons providing aircrew with a 406MHz with embedded GPS beacon as a plug and play replacement. Once on the ground the pilot can utilise the integrated antennas including GPS to provide portable functionality. With visual indicators and audible…
Multi-beacon DF Single compact antenna unit High sensitivity receiver Fully COSPAS-SARSAT compatible The Techtest DF system is designed to reduce the time to locate emergency locator beacons. It is compatible with both 121.5MHz swept tone distress beacons and 406MHz COSPAS-SARSAT transmissions on current and future frequencies. The user is able…
The 12-406-9 is a handheld 406 decoder that receives and decodes COSPAS SARSAT distress or test messages. The unit can be set-up to monitor all transmissions (including tests) or distress only. COSPAS/SARSAT 406MHz Detection and Decoding Messages decoded and displayed in an easy to understand format Touch screen interface Internal…
As manufacturers of antennas and SAR equipment, the company has always believed it of great importance to provide supporting equipment to these products. Over the years, this has resulted in a range of Test Sets being manufactured by Techtest. Our range of VSWR Test Sets is known throughout the aviation…
The need for Search and Rescue (SAR) services to accurately detect and locate the distress signals from emergency beacons resulted in Techtest developing its range of Homing Systems. These use a phase comparison method to provide left-right steering information, to the SAR pilot enabling him to locate emergency beacons operating…
The Next Generation of ELT The latest upgrade to the HR Smith 503 ELT series utilises the Iridium satellite network to provide an independent aircraft tracking and alerting function. The addition of the Iridium service to the existing full Cospas/Sarsat coverage and transmission of last known GPS co-ordinates hugely increases…
