Classification: CPC G  B | IPC B  G

Claim 12:
13. A system for position calculation of an antenna, the system comprising:
an antenna on a first vehicle adapted to transmit and receive electromagnetic waves;
a processor adapted to
calculate, by range measurements between the antenna and at least three transponders on a second vehicle, ranges between the antenna and the at least three transponders, wherein respective positions of the at least three transponders are known,
provide a first antenna coordinate of three antenna coordinates indicating a position of the antenna, wherein the first antenna coordinate is assumed for or known before predicting the ranges between the antenna and the at least three transponders,
calculate second and third antenna coordinates of the three antenna coordinates based on the calculated ranges between the antenna and the at least three transponders;
predict ranges between the antenna and the at least three transponders based on the assumed or known first antenna coordinate and the calculated two antenna coordinates;
perform an optimization process based on the calculated ranges and the predicted ranges to infer an optimized position of the antenna; and
steer the first vehicle for landing on the second vehicle based on the optimized position of the antenna.
