Embodiment Construction

[0023] Logistics vehicle management, battlefield assessment, impact point report, combat command, individual broadcast information, etc. belong to this type of system. The system is divided into a terminal backhaul system (called "incoming" or "incoming" link), and a broadcast communication link (called "outgoing" or "outgoing" link). The system structure is shown in Figure 1.

[0024] From the perspective of equipment composition, the system consists of space segment, communication center, user center and user terminal.

[0025] Space segment resources: Various types of communication satellites are used, but the use of decommissioned satellites (patent application number: 200610055909.2) greatly reduces the cost of system construction and operation. A low-rate data communication network is established by using the remaining transponders of CAPS decommissioned communication satellites as space segment resources.

[0026] Communication Center: An antenna with a caliber of 10-1...

Abstract

The invention relates to the space orientation and the communication domain, which based on guidance correspondence integration system of the time position and status messages. The system use central station with the heavy-caliber antenna as relaying, can support the information feedback service about the guidance terminal, and can also support the broadcast service about the tie-station. Even in the region communication network can not cover in the ground, using the own satellite resources of repeater type satellite navigational system, can complete guidance and correspondence function, can orient any user's position in any place of the world precisely, which is effective supplement of the the repeater type satellite navigational system, especially suit for oceangoing voyage, and battle, research, exploration in the unpopulated area.

Description

technical field [0001] The invention relates to the field of space technology, and is a system design for realizing communication functions by utilizing the resources of the navigation system itself, in particular, a navigation and communication integrated system based on time, position and status information. Background technique [0002] The current satellite navigation system only has the functions of navigation, positioning, and timing. In fact, navigation users need to transmit information while positioning, and also need to obtain some required information. However, these requirements cannot be realized by the system itself, such as reporting to the center. Business requirements such as the location of the user, the order issued by the receiving center to the user, etc. The traditional method is to combine the navigation and positioning system with other communication systems to complete the above functions, such as the combination of the satellite positioning system (...
