Many future space missions to asteroids and comets will implement autonomous or near-autonomous navigation, in order to rosy teacup dogwood save costly observation time from Earth tracking stations, improve the security of spacecraft and perform real-time operations.Existing Earth-Spacecraft-Earth tracking modes rely on severely limited Earth tracking station resources, with back-and-forth delays of up to several hours.In this paper, we investigate mpu63zm/a the use of CONSERT ranging data acquired in direct visibility between the lander Philae and the Rosetta orbiter, in the frame of the ESA space mission to comet 67P/Churyumov-Gerasimenko, as a proxy of autonomous navigation and orbitography science capability.
