Problems solved by technology

[0005] In today's on-orbit target positioning, the demand for fast and high-precision positioning for dynamic target capture is increasing. In addition, the limitations of on-board computing and storage resources make it impossible to use traditional geometric positioning models for on-board real-time positioning operations.
And the geometric correction of each positioning also needs to download the parameters and other data through the payload, which occupies more satellite communication resources and does not have the characteristics of real-time

The positioning calculation processing system adopts a positioning calculation algorithm model after matching optimization, the optimized algorithm model needs to be quickly positioned in a limited external resource environment on the premise of ensuring precision, the superiority of the algorithm model is guaranteed, devices in apositioning calculation processing module can complete the reception, caching, distribution and positioning calculation of image data effectively and quickly, and the purpose of real-time high-precision on-orbit positioning is achieved.

Description

technical field [0001] The invention relates to a positioning solution processing system. Background technique [0002] As the core technology of fast and uncontrolled geometric positioning of optical satellite images, on-board high-precision real-time positioning and calculation technology provides real-time object position information of detection targets without ground processing, and realizes positioning and movement of moving and static targets Analysis of the target's trajectory and behavioral intentions. [0003] The high-precision on-board real-time positioning technology means that all the positioning and calculation processes are completed on the satellite, and there is no need to transmit image data to the ground for processing, which greatly reduces the time required for positioning and calculation, so as to achieve real-time positioning of dynamic targets the goal of. Therefore, it can realize the fast and uncontrolled geometric positioning of optical satellit...
