Other satellite information systems select the short message channel of the high rail star of Beidou.
The step 3) completes the detailed process of fast worktodo planning on star are as follows: satellite refers to the ground-based mission of upper note
It after enabling codeization handle, is matched with the binding instructio in spaceborne database, is indexed by binding instructio number, and is quickly real
Apply mission planning.
It is described that quick obtaining 4) is carried out to response message method particularly includes: posture is rapidly completed in satellite in 50~100s
Motor-driven, imaging and data processing, and carry out data down transmission.
The data down transmission method particularly includes: imaging satellite in the visual segmental arc of ground based terminal, take it is point-to-point or
It is point-to-area to direct transfer；In the non-visual segmental arc of ground based terminal, image-forming information is quickly transmitted imaging satellite by inter-satellite link, is reached
Ground receiving wastewater facility.
The reception terminal use when data down transmission includes mancarried device antenna and hand-held task terminating machine；It can be fast
Speed exhibition is received, and automatically with star servo, is realized the foundation and transmission of self-adaptive descending link, is demodulated, decoded according to standard, obtains
Image information；The mancarried device antenna aperture is less than 1m.
The advantages of the present invention over the prior art are that:
(1) satellite is substantially improved for the responsiveness of task, can reach minute grade by ten minutes
(2) satellite executes the flexibility of task, customization degree is substantially improved, can quick obtaining be arbitrarily designated the task period
Customization information, can also be achieved the task that existing satellite cannot achieve and temporarily change pouring functions.
(3) it supports the type of Ground Application more abundant, not only supports existing satellite transit control system, moreover it is possible to directly prop up
Holding ground portable terminal, even handheld terminal task is directly initiated and data directly receive.
(4) task chain that independent completion is formed between the high rail star of Beidou and applied satellite is ground using commercial product, low cost
System, the operation of rapid deployment, constellationization.
(5) system model is mainly directed towards further types of user terminal, be especially but not limited to non-traditional type user and
Mobile and mobile information receives terminal, realizes that quick initiation of the task to customized task or emergency response type task, realization are directed to
Goal task is rapidly completed.
(6) system model is by the interactive applications on star with ground based terminal, and is directed to the small-sized reception device in ground,
Realize the quickly biography and directly application down of data on star.
