Technical Session VIIIA: Innovative Mission Operations Concepts
Abstract
A major cost saver in low-cost missions is reducing operation costs. This paper outlines the work carried out at Surrey Space Center (SSC) to reduce the time required to generate image schedules for tasking the remote sensing satellites. The principle and basic algorithms of an innovative imaging prediction approach are first briefly presented, which result in a fast imaging prediction software, the ImPredict. Experiment results show that its prediction speed is several orders of magnitude faster than the traditional trajectory-checking approach while kee ping an even better accuracy. The software has currently been implemented as windows DLL, written in ‘C’, which has been linked into the SSTL off-axis scheduling system for practical application for the UoSAT-12 and Tsinghua-1 missions. Its future applications for formation satellite missions are further prospected.
