The study aims to develop and validate an alternative metrology algorithm for accurate formation flying of satellites in the PROBA-3 mission.
Implemented an alternative algorithm using Cardano's method for radial sensor positioning.
Compared performance of the alternative algorithm against a flight algorithm.
Validated the alternative algorithm during the ASPIICS calibration campaign.
The alternative algorithm achieved higher accuracy in regions with larger positioning errors.
The computational cost of the new method is significantly higher than the flight algorithm.
Comparative analysis shows advantages for both algorithms depending on operational conditions.
