dBm

dBm develops and manufacturer's Satellite Linik Emulators which when used alone or combined with their Up/Down converters can emulate a space based communication channel to allow the testing of satellite payloads and earth terminals. By dynamically changing delay, path loss, phase shift, frequency offset and flat fading, the user can simulate virtually any satellite orbit using dBM's SATGEN ephemeris data generation sofware or by creating their own data files.
