Patent ID: 8755950

Claim:
A termination system for remote termination of an unmanned vehicle communicatively connected to an unmanned vehicle control station via an air interface, said termination system comprising: one control station portion located in said control station comprising a control station computer comprising a counter value generator adapted to generate, on a cyclic basis, different counter values; a termination device adapted to generate, in each cycle, a control station code by running a counter value through a termination algorithm; a transmitter adapted to transmit, in each cycle, the counter value and the control station code generated from the counter value to the unmanned vehicle in form of a counter value/control station code pair, via said air interface, and a termination actuator which, when actuated, is adapted to prevent counter value/control station code pairs in which the control station code has been generated from the counter value from being transmitted to the unmanned vehicle, and a vehicle portion comprising a receiver adapted to receive the counter value/control station code pair transmitted from the control station in each cycle; and an unmanned vehicle computer connected to said receiver and adapted to: generate an unmanned vehicle code by running the counter value in the received counter value/control station code pair through a termination algorithm corresponding to the algorithm used to generate the control station code in the control station, and compare the control station code in the received counter value/control station code pair with said generated unmanned vehicle code to establish whether the counter value/control station code pair and the generated unmanned vehicle code differ from each other, in which case a termination event of the type code termination event has occurred, and a termination decision unit configured to decide whether or not to terminate the unmanned vehicle based on the occurrence of any termination events, wherein the termination decision unit is further configured to effectuate termination of the unmanned vehicle if no counter value/control station code pair has been received by the receiver in at least one consecutive cycle.
