Claim 11:
12. A non-transitory computer-readable data carrier having stored a computer program product, the computer program product comprising instructions which, when the computer program product is executed by a computer, cause the computer to carry out a method for position calculation of an antenna, the method comprising:
calculating, by range measurements between an antenna on a first vehicle 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;
providing 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;
calculating second and third antenna coordinates of the three antenna coordinates based on the calculated ranges between the antenna and the at least three transponders;
predicting 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;
performing an optimization process based on the calculated ranges and the predicted ranges to infer an optimized position of the antenna; and
steering the first vehicle for landing on the second vehicle based on the optimized position of the antenna.
