Technical field
A kind of data high-speed communication means based on moonlet cluster MANET of the present invention, belongs to satellite formation networking technical field.
Background technology
Existing communication satellite constellation systems, such as iridium satellite, GlobalStar, satellite is positioned at different orbital planes, forms fixed signs configuration, and satellite-to-satellite link is determined; And Small Satellite Formation Flying's system, such as Techsat-21, TanDEM-X, GRACE etc., the same fixedly formation configuration that adopts, these systems have only been set up fixing intersatellite communication link, do not possess exchanges data and multi-hop transmission ability between star, still be not enough to be referred to as network between star, more can not realize MANET.
The F6 system concept that the U.S. proposes, system energy autonomous operation, support module adds/exits, and in cluster, each module realizes resource-sharing by network, in the face of threatening, can realize Autonomous Reconfiguration.But this system does not provide concrete cluster networking implementation method, does not relate to data high-speed transmission problem yet.
This patent designed system and method with at present both at home and abroad in orbit and in document patent designed system all not identical, there is certain novelty.The basic condition of related system is as follows:
(1) satellite constellation system
(1) Iridium system
The basic condition of IRIDIUM has been described in document " second generation IRIDIUM and lift-launch application scenario thereof, Wu Jianjun Cheng Yu is new etc., the 6th satellite communication new business new technology Annual Conference, 2010.3 ": 66 MEO/LEO Satellite Constellation.
(2) Globalstar system
Document " the eight convergent points soccer star system outline of satellite communication series of lectures; Zhang Gengxin Li Gang etc.; the digital communication world; 2007.12 " has been described GlobalStar basic condition: 48 MEO/LEO Satellite Constellation form with 38 ground gateway stations that are distributed in the whole world, 16 wave beam fixed beam antennas, without inter-satellite link, transparent forwarding on star.System Construction, Operations, Administration and Maintenance cost are very big.

(2) satellites formation system
Existing distributed satellites system generally designs for particular task in the world at present, every satellite configuration is identical, integrates several functions, and annexation is based on system function design, generally can not change according to the variation of task and demand, adaptivity and autgmentability are poor.Such as, Techsat-21 plan interstellar distance is at 100m to 5km, and inter-satellite link is mainly the situation of transmitting formation position temporal information and load, and speed is only 128bps
[2]; Between TanDEM-X task star, interactive information is mainly positional information and the attitude state information of GPS, and every 10s sends with 32kbps
[3]; GRACE inter-satellite link has distance measurement function
[4].
Network facet between star, existing system has only been set up fixing intersatellite communication link, does not possess exchanges data and multi-hop transmission ability between star, is still not enough to be referred to as network between star.
(3) F6 satellite system
For the deficiency of distributed isomorphism satellite system, U.S. national defense advanced research projects agency (DARPA) has proposed separation module concept, and has carried out the F6 project [5,6] that realizes this concept.The English full name of F6 is " Future; Fast; Flexible; Fractionated; Free-Flying Spacecraft ", literal translation for by information exchange, connect " following, fast, flexibly, separation module, free flight spacecraft ", be technical research and the demonstration and verification project that U.S. national defense advanced research projects agency carries out separation module concept.
The LEO that U.S. DARPA plans to carry out F6 at 2014-2015 is demonstration and verification in-orbit, and this verification system called after " Pleiades " (Pleiades).Initial target is only its functional attributes that realizes distributed system, i.e. 1. system energy autonomous operation, and support module adds/exits; 2. in cluster, each module realizes resource-sharing by network; 3. in the face of threatening, can realize Autonomous Reconfiguration.
" Pleiades " is (Pleiades) by 7 module compositions, each module flying instrument is controlled functional unit (ACS) and communication function unit (Communications) for general functional unit-platform, to realize module group's formation control and group-net communication.On general utility functions cell location basis, the dedicated functional unit of disparate modules aircraft configuration difference in functionality, comprises transducer load (sensor) unit, storage (Storage) unit, data processing (Processor) unit etc.The module aircraft that has configured dedicated functional unit can complete corresponding special function in module group formation system, between each module aircraft, by communication function unit, realizes on star large capacity storage, data processing and the resource-sharing such as transmission over the ground.
Communication unit between F6 demo system module spacecraft adopts self-organization network technology to realize group-net communication, employing is without central site network structure, between module spacecraft, be peer-to-peer communications node, have without features such as centralization, self-discovery, configuration automatically, self-organizing, fault self-recovery and high reliability and high availability.
But the functions such as all group-net communications of this system, detection data transmission realize by communication function unit is unified, group-net communication is generally low speed directional communication, and detection data is transmitted as high speed beam communication, both integrate and influence each other, autgmentability is poor, and especially the transmission demand for two-forty is difficult to meet very much.And this system does not provide concrete detection data transmission method.
