Abstract: A system comprises: onboard a first craft, called host craft, a triplet of antennas comprising a transmitting and receiving antenna and two transmitting antennas, a transmission chain that can be successively coupled to each antenna of the triplet of antennas by a radiofrequency switch, a reception chain that can be coupled to the transmitting and receiving antenna, and a processing device intended to determine a relative angular position between, on the one hand, the host craft and, on the other hand, a plurality of spacecraft, called companion craft, from measurements of path differences performed and transmitted by the companion craft; onboard the companion craft, a transmitting and receiving antenna, a transmission chain and a reception chain coupled to the transmitting and receiving antenna and a measurement device intended to measure path differences between three signals originating from the three antennas of the triplet of antennas of the host craft.
