摘要：Since the beginning of earth observation satellites the dynamic disturbances have a strong impact on satellite design. During satellite conception and realisation, they are closely analysed, often with alarmist budgets. … But so far most satellites have such a good stability that these disturbances are even difficult to characterised during in-flight commissioning.. However the recent needs to design smaller satellites, more compact and with higher sampling resolution make these dynamic perturbations more probable and critical. The correction of these disruptive vibrations thus becomes an important issue, and induces the establishment of a ground processing to improve the retrieved satellite attitude. . In this paper, we present a generic algorithm (an integration method) which allows us to estimate the disruptive signal from several differential observations derived from imagery. Applied to the PHR system in order to secure the budget of geometric stability, this innovative processing gives very accurate results (maximum error is 10% of a pixel).
