| Abstract: |
| To satisfy the communication demands of remote local war, a small sate
llite relay based remote communication scheme is proposed. The composition and
working principle of
remote communication system are analysed,orbit parameters of s
mall satellite are calculated according to environment factors. Small satellites
communication relay constellation of medium elliptic recursive orbit is structu
red, and communication between fighter and combat command center is realized. Th
e coverage mo
del of small satellite relay based remote communication is built by STK softwa
r
e, and simulation results show that the average coverage rate of target area is
99.6
9%, available connection time rate of combat command center and fighter is 98.26
%. |
