Abstract

The invention provides an integration method and an integration system of a remote sensing satellite receiving system. In the remote sensing satellite receiving system, an integrated channel design is adopted, a radio-frequency switch matrix, an intermediate-frequency balance switch matrix, a base-band data change-over switch and a testing switch are configured in a channel and are used, thus various devices in the integrated channel are connected, and the sharing of a tracking and receiving device and a testing device in the remote sensing satellite receiving system can be realized; data transmission of a radio-frequency signal from an antenna to a computer room can be completed by adopting an optical cable; the output capacity of a demodulation data network can be increased while an original base-band data output interface of a digital high-speed demodulation device is reserved, and a high-speed Ethernet is utilized for connecting the demodulation device and a recording device; task management and device control on multiple sets of integrated remote sensing satellite receiving systems can be realized by adopting a control and management system which is in integrated planning. By utilizing the integration method and the integration system, provided by the invention, device sharing can be realized, the device utilization rate can be increased, and meanwhile, the expansion of the remote sensing satellite receiving system is convenient.

Description

technical field [0001] The invention relates to the technical field of remote sensing satellite receiving, and more specifically, relates to an integrated system of remote sensing satellite receiving system. Background technique [0002] With the development of national informatization and the commercialization and industrialization of remote sensing applications in many sectors of the national economy, people's demand for remote sensing satellite applications has increased sharply. higher requirements. In order to meet the needs of various industries for the comprehensive utilization of medium and high-resolution satellite remote sensing information, the remote sensing satellite ground receiving system is also developing rapidly, realizing multi-satellite, all-weather, all-time earth observation. [0003] The ground receiving station has multiple sets of remote sensing satellite receiving systems. Although the calibers of the receiving antennas of multiple sets of remote s...

AI Technical Summary

Problems solved by technology

[0004] 1. The equipment between the receiving systems of the ground receiving station is exclusive to each other, and the purpose of sharing cannot be achieved. In fact, the channel equipment such as the frequency converter and demodulator of the receiving system is common equipment for each receiving system;

[0005] 2. The equipment interface specifications of each set of receiving systems in the ground receiving station are diverse and cannot be interchanged and used universally;

[0006] 3. Each receiving system has its own control and management software. The existing ground receiving station cannot perform unified task and equipment management for multiple receiving systems of the receiving station, which increases the burden on operators

[0008] 1. The existing remote sensing satellite receiving system uses cables to realize all kinds of data transmission between the antenna and the computer room. Since the cables are more likely to be struck by lightning, the receiving station often has equipment failures caused by the cables being struck by lightning;

[0009] 2. The baseband signal output of the demodulator mostly adopts ECL level. With the continuous improvement of the code rate of the demodulator output signal, the ECL output of the demodulator cannot meet the transmission requirements of long-distance high-code-speed data
