The BSSG is a custom-made test instrument. Its purpose is to simulate the simultaneous activation of multiple distress beacons to test the capabilities of various Cospas-Sarsat system components. The BSSG contains eight 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 generators provide the capability to produce up to eight 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 BSSG control software provides the capability for configuring simulated beacon signals and complex test scenarios.
