Spacecraft relative navigation
WebRelative spacecraft navigation based on Global Navigation Satellite System (GNSS) has been already successfully performed in low earth orbit (LEO). Very high accuracy, of the order of the millimeter, has been achieved in post-processing using carrier phase differential GNSS (CDGNSS) and recovering the integer number of wavelength (Am- WebAbstract—Relative navigation remains the most challenging part of spacecraft rendezvous and docking. In recent years, flash LIDARs, have been increasingly selected as the go-to …
