Abstract
A secure communication hub (10) relays local communications between low probability of intercept (LPI) user radio equipment (68) and provides a secure interface with a command center (58) through a non-geostationary commercial satellite communication system. The secure communication hub (10) includes different radio interface units (12) for communicating different data formats with the (LPI) user radio equipment (68). Encryption and decryption circuitry (18) provides for different security levels and different keys for the (LPI) user radio equipment. Links with the satellite system are secured using encryption.
