Location management is one of the key points of movement management in low orbit satellite. Comparing with static location area, dynamic location area can reduce the cost of movement management, which is determined by the characteristic of user movement. In fact, each user only keeps two counters, one is the distance moved and another is the time passed. A location update is performed when this counter...
IEEE 802.11 protocol is widely used in Wireless Local Area Networks (WLAN) for its high data transmission rates. The formation flying satellite system has a short inter-satellite distance, which is similar to WLAN. It may be a good choice to apply IEEE 802.11 protocol in inter-satellite communication to increase throughput. However inter-satellite distance is longer than what desired by WLAN, so IEEE...
A design method for optimal regional coverage satellite systems with common track constellation (CTC) is proposed. CTC is a special class of constellation in which satellites of whole constellation follow the same track on the Earth's surface-hence the name common track. Based on the thorough investigation on the constraint relation of the satellite parameter, a coded notation for CTC is presented,...
