The AVMM ELT-S 406 is an aeronautical survival beacon designed for liferafts.

This new generation of ELT complies with the latest regulation and offers all the improvements of the COSPAS-SARSAT system with the 406 MHz frequency :
- Global coverage
- Precise pinpointing
- Identification of the aircraft in distress (the ELT transmits a unique aircraft identification number)
- Efficient process of false alarms to avoid costly search and rescue operations

The AVMM ELT-S 406 transmits on all 3 emergency frequencies (121.5/243.0 and 406 MHz). The ELT is manually activated during a crash and transmits the standard swept tone on 121.5 and 243.0 MHz. Every 50 seconds for 440 milliseconds the 406.025 MHz transmitter turns on and transmits an encoded digital message to satellite system. The ELT AVMM ELT-S 406 is programmed with either the aircraft tail number, a serial number or the aircraft operator designator. This operation takes only a few seconds.

An integrated "self test" checks the main functions of the beacon.

406 MHz ELT Tester (Test Set)

406 MHz / 243 MHz / 121.5 MHz ELT TESTER is designed to check the avionics emergency locator transmitters (ELT) operating via COSPAS-SARSAT system. It provides accurate testing in volume of annual or maintenance requirements or fast check after ELT's encoding or installation in accordance with USA (FAA Part 91.207), Canada (CAR 571 Appendix G), Europe (CAA/EuroCAE) requirements.

ELT Tester Mini w/ Wi-Fi

ELT Tester Mini w/ W-Fi is third generation device designed to check the avionics emergency locator transmitters (ELT) operating via COSPAS-SARSAT system. Tester is operating with any mobile phone or desktop PC by means of Wi-Fi connection. It is small and light-weight. The ELT tester provides demodulation and complete decoding of Cospas-Sarsat messages. Test results will be displayed in your mobile phone, tablet or PC. All tests will be stored in internal memory for future use.

BT-611M Beacon Tester

BT-611M Beacon Tester is designed for high accuracy and resolution measurements of the full set of beacon signal parameters to check its compliance with the ones, specified in C/S doc. T.001, T.007. The tester is succesfully used for Cospas-Sarsat type approval certification process. It is professional specified test equipment for beacon manufacturers or test laboratories, service centers.

Beacon Simulator BG-105

Beacon Simulator BG-105 is high-precision simulator of Cospas-Sarsat emergency beacon messages. BG-105 allows to simulate up to five simultaneously operating beacons with messages overlay in time. The generator is intended to operate under PC control to provide the customization of main parameters of each simulated beacon on every of five channels by means of terminal program.
