Galileo Reference Beacon Generator BG-105 (further – generator) is high-precision simulator of Cospas-Sarsat emergency beacon messages (EPIRB, ELT, PLB operating in 406MHz frequency range). 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.

Galileo Reference Beacon Generator BG-105 is a custom-made test instrument. Its purpose is to simulate the simultaneous activation of multiple distress beacons. The BG-105 contains five independent frequency generators, each capable of producing either a stream of time-multiplexed signal pulses from one or more beacons or a continuous wave output. The generator provides the capability to produce up to five concurrent beacon transmissions. The net effect is the production of multiple beacon signals with possible overlaps in both time and frequency. The sum of the outputs from the generators can be amplified by a high-powered RF transmitter before delivery to the appropriate antenna. The BG-105 control software provides the capability for configuring simulated beacon signals and complex test scenarios.

We also offer Galileo Reference Beacon Generator BG-102 version which has the same specification but reduced to 2 number of channels.

Galileo Reference Beacon Generator BG-105 and BG-102 allows to:
- Generate Beacon Test Sequences under Cospas-Sarsat standards in 5 and 2 channels accordingly.
- Simulate a large number of beacons for system capacity tests.
- Vary the radio frequency and data content parameters associated with each beacon transmission.
- Add interfering carriers or white noise to the beacon transmissions.
- Simulate collisions between beacons.
