TDMA satellite communications system has reserve off-line units - synchronised to main on-line units and continuously checked

Abstract

Abstract The TDMA satellite communications system has an off-line unit in the TDMA end station in addition to its on-line unit. Both off line and on line units are synchronised to the operating unit and continuously checked in such manner that the off line unit causes a simulation of the received signal burst by the operating unit multiplex control signal. The on line units synchronising the phase of the off line unit multiplex control signal to the phase of the operating unit multiplex control signal. Additional monitoring circuits may be provided in both the operation and stand-by systems. The latter being formed by the off line units.
