radio engineering. SUBSTANCE: system has terrestrial measuring stations receiving navigation signals from navigation satellites and transmitting navigation parameters via corresponding communication channels to a processing center, N, where N>=1, peripheral processing stations connected to the processing center via a common access communication channel, M sets of user navigation devices connected to each of the peripheral processing stations through narrow bandwidth communication channels. EFFECT: higher flexibility in fitting source radio navigation parameters to requirements of end users. 2 dwg |
