A new TDMA technique is introduced into inter-satellite network of satellite navigation system,which allows a satellite to seize the timeslot of another satellite.The delay of waiting for transmitting signal is reduced significantly comparing with the traditional TDMA.The optimum object of timeslot assignment is formulated for the new TDMA technique.According to the inter-satellite visibility of the navigation constellation,an algorithm is proposed to achieve the object of the timeslot assignment based on the vertices coloring theory.The simulation results show that the communication system is improved significantly by the new TDMA technique without influencing the satellite obit determination and URE performance comparing with the TDMA adopted by GPS.
