| Abstract: |
| Through analysing current adjustment modes of antenna′s angle of the se
rvo system in shipborne satcom station,this paper points out that all of the mod
es ignore the
influence of position changing and certain cases on antenna tracking. A composit
e mode in which the adj
ustment is based on real-time theoretical ground angle is advanced. This mode c
an av
oid some adverse influence of high pitching angle on auto-tracking and overcome
the unfavourable factors caused by
over-top tracking, keep communication omnidirectional and no blind
spot,and ensure unblocked communication. |
