Title: Control system synchronisation
Inventor: OUTRAM JOHN DOUGLAS
IPC: H04B1/707
Filed: 1987-07-08
Abstract: A control system is described for establishing synchronised control of a vehicle, such as an unmanned aircraft, which is either out of contact with, or has lost synchronised control with, a ground control station. The control system is provided with a communication system at the vehicle for determining when the vehicle is out of synchronised control with the control station and for transmitting distress bleats in the form of a short spread spectrum sequence to a receiver at the control station. Synchronised communication with the vehicle is achieved by a process of repeated rapid two-way communication employing pattems of super-imposed phase modulation of the short spread spectrum sequences of signals, the modulation patterns increasing in length with each repetition to achieve a gradual decrease in ambiguity. Thereafter a long spread spectrum code sequence is employed for transmitting an appropriate operation schedule to the vehicle.
