Abstract

The invention discloses a dynamic variable multi-data-format satellite-assisted data processing system. The system comprises a state parameter processing module, a scanning information processing module, a satellite timekeeping and calibrating module and an auxiliary data synthesizing module. The state parameter processing module receives satellite parameters, camera parameters and broadcast benchmark parameters, conducts classification after verification and sends the parameters to the respective modules to be processed. The satellite timekeeping and calibrating module processes input pulsesper second, internally generates a 1M clock microsecond counter, and receives and calibrates broadcast benchmark time. The scanning information processing module sends angle collecting pulses to obtain scanning angle information, receives a camera series, dynamically updating the scanning angle information according to the series value, and ensures that star map data strictly corresponds to the scanning angle during operation. The auxiliary data synthesizing module conducts scheduling according to the satellite data format, outputs frame header information when frame synchronizing starts, outputs line header information, star map data and end-of-line information when line synchronizing starts, and outputs end-of-frame information when star map data ends.

Description

technical field

[0001] The invention relates to a dynamically variable multi-data format satellite auxiliary data processing system, which can receive and process various complex and dynamically variable multi-data format satellite auxiliary data, and belongs to the technical field of satellite communication. Background technique

[0002] With the development of satellite remote sensing technology, all kinds of users have higher and higher requirements for image information, and at the same time, they have higher and higher requirements for auxiliary data such as current camera status and satellite parameters, with data formats and types becoming more and more complex, and output forms Changeable and other characteristics. For example, the large elliptical orbit early warning visible video processor is used to receive the visible star calibration data through the visible light channel when the camera is calibrated on the orbit, and to plan and set the camera scanning paramet...

Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as figure 1 Shown is a block diagram of the peripheral structure of the dynamically variable multi-data format satellite assistance data processing system according to the embodiment of the present invention. The management controller sends the second pulse and the three-wire serial port command or data to the auxiliary data processing system. There are three types of three-wire data. The first type of camera parameter 32bit data such as CCD series, AD gain, integration time, etc.; the second type of satellite parameters, respectively Send 3 packets, each with 42 pieces of 32bit data; the third type is the broadcast reference time, 3 pieces of 32bit data. The auxiliary data processing system receives the scanning start signal, generates a frame synchronization signal and a line synchronization signal, and sends an angle sampling ...
