Description
Technical field
1, space-based mobile multifunctional network system invention relates to the super far away/information transmission network systems technology closely of becoming one such as moving real-time dynamic image transmission technology, satellite positioning tech, high-speed data mobile communication technology and communication technology of satellite.This network system be have real-time clear dynamic image, satellite accurately multifunctional informations such as location, high-speed data and digital voice move remote termination and command centre station in incorporate high-performance, the network architecture of the low cost flexible of forming through ground-star transponder (station), satellite communication link can transmit interactive mobile multifunctional information.
2, ground-star transponder (station) invention relates to a kind of high-performance, portable, the land mobile communication wireless transmission transponder (station) of (or the forwarding of ground plane) of transferring each other with satellite communication link cheaply, be the space-based mobile multifunctional network system super far away/closely transmit the important key components of information.
Technical background
1, present widely used second generation mobile communication and the third generation land mobile communication (W-CDMA, cdma2000 and TD-SCDMA) that developing now wait not that has accurately (1-3 rice) geo-localisation information and interactive mode transmission; Operation networking investment is very big, and it is slow, dumb to build the networking of the rare density telex network of overlength distance, and equipment investment is big, and cost price is than expensive.China's 3G (Third Generation) Moblie system (TDD), also unsuitable high-speed mobile destinations traffic.
2, the existing second generation and 3G (Third Generation) Moblie, covering for rare density remote subscriber is to solve with satellite transmits, normally carry out forwarding information with the VSAT ground satellite station, transmit the mobility transmission information of finishing with vehicular VSAT ground satellite station, cost of investment is big, and limit by traffic, region and environment, so mobility is limited; Equipment cost and first networking expense and maintenance expense are all higher; It is also bigger to run professional service charge.
Summary of the invention
1, existing mobile communication can not low-costly drop into, flexible networking in order to solve, can not hang down the interactive mode of maintenance expense super far away/multifunctional all information such as short range transmission is accurately located, real-time clear dynamic image and high-speed data communication.For this reason, the present invention proposes space-based mobile multifunctional network system and ground-star transponder (station).This network system is by central station (mobile command center), mobile remote termination (hand-hold type or vehicular), the maneuverability that ground-star transponder (station) and satellite link are formed, the super far away/short range transmission network system of low cost have that real-time transmission is accurately located, mutual functions of multifunctional information such as dynamic image, high-speed data and voice communication clearly.Command centre by system can be in time super far away/closely monitor, control and commander locates region of war or regional field data.Look concrete instructions for use, can be neatly cloth small-area network system, big local area network system, section industry network system fast ... each single central station system constitutes star network, the multicenter station via satellite link can constitute on a large scale, the mesh network system of overlength distance (or constitute big regional network mesh network system by ground-star transponder).
The technical solution adopted for the present invention to solve the technical problems is: realize that the mobile remote termination (hand-held or vehicle-mounted) of accurate status, the integrated designs of multifunctional information such as dynamic image, high-speed data and voice communication in real time and central station and the network architecture of ground-star transponder (station), satellite link composition design; Design simultaneously high-performance, low cost, light ground-star transponder (station) solve switching super far away/near message transmission.
Fig. 1 is a space-based mobile multifunctional network system structure, and A is central station (command centre); B is remote termination (individual soldier, vehicle-mounted, airborne, ship carries or user's hand-held set); C is a ground-star transponder (station) (or ground forwarding), and the information of (1) central station or remote termination is transmitted and broadcast TV programs by satellite, otherwise or.(2) under the situation of communication distance than far away or landform obstruction, the information of transmitting remote termination is to central station; D is a satellite repeater.The technical performance of central station and remote termination is the core and the embodiment of whole network system, whether establishes ground-star transponder (station) and depends on distance, the landform of central station and remote termination, the factors such as the influence of communicating by letter of atural object.Its main performance technical indicator is: information integrations such as (1) real-time clear dynamic image, accurate geographic location, high-speed data and voice communication integrated, super far away/closely transmit alternately, (2) channel width: 1.25MHz, (3) image definition: 720*560,1Mbps, MPEG-4, TPEG2000, (4) positioning accuracy: 3 meters-1 meter, (5) system data error rate is better than 10
-7, (6) receiving sensitivity is better than-110dBm, (7) remote termination (handing) weight :≤400 grams.
This network architecture can make up complete distinct area (region of war or area or industry department) network system, finishes command centre to information interaction and commanders such as the dynamic image that is equipped with remote termination personnel, moving vehicle (machine, ship) situation, position , data, voice.Information exchange between information exchange between the operation cluster and cooperation commander or the industry department, available a plurality of central stations constitute network and finish business function.Characteristics such as this network configuration has flexibly, quick, networking small investment, cost and maintenance expense are low.Be suitable for quick establishment and standardization to establish ; Be easy to set up super far away/short range transmission and can be greatly, network operation system that can be little.
2, for solve low-cost input, networking flexibility, operation maintenance expense low super far away/closely transmit multi-functional transmission information, the present invention designs a kind of ground-star transponder (station), at remote termination and central station, far away or terrain environment is obstructed under the situation because of communication distance, remote termination information can't and central station between carry out information interaction when transmitting, installation ground-star transponder (station) forwarding information is to central station or be forwarded to satellite transmission information to central station, otherwise or.
The technical scheme that its technical problem that solves this locality-star transponder (station) adopts is: the multifunctional information according to remote termination (hand-hold type or vehicular) and central station passes a parameter and feature and satellite transmits parameter and feature alternately, designs high-performance, low cost, portable ground-star transponder (station).
