Abstract

Tiangong-2 ground data processing and service system is a specialized software which has been used for processing the products of three earth observation payloads and other several space science experiments. In the course of geometric rectification on the Wide-band Imaging Spectrometer data, a high-precision sensor model of the wide-width virtual camera is established to improve the geometric positioning precision. Towards the Interferometric imaging radar altimeter (InIRA) product processing, a series of steps should be performed to generate backscatter coefficient images and surface topography data, such as imaging processing, interferometric processing, radiometric correction and geometric location. After the production of these categories of products, several indicators included signal to noise ratio, clarity, contrast, comentropy and the radiometric accuracy were adopted to assess and control the products quality. As a part of complete process, the space application data promoting service platform for China Manned Space Engineering provide all the products of earth observation payloads and other space science experiments.
