Optimal impulse orbit-transfer for making small satellite constellation;

Design of simulation platform for high precision laser communication small satellite constellation;

Finally, we present several presumptions aiming at small satellite constellation′s measurement and control, while not.

Study of geometric characteristics of inter-satellite links between LEO layer and MEO layer in LEO/MEO satellite constellation;

Tentative plan of a micro-satellite constellation used for reconnaissance;

The Study on Architecture and Key Technologies of the Military Satellite Constellation Communication Network Based on NEMO;

Handoff data registration strategy in satellites constellations communication system;

In order to minimize the mobility management signaling cost, the general scheme is to reduce the location update interval and the use of paging beams in satellites constellations communication system.

Call drop will occur when no satellite can be visible,handoff is not real-time and the corresponding response is lost in satellites constellations communication system.

Analysis of the probability of target detection and max access gap of reconnaissance satellite constellation;

Focused on regional reconnaissance, a novel reconnaissance satellite constellation design method based on the GA (genetic algorithm) is proposed in this paper.
