SPOT-5 DORIS oscillator instability due to South Atlantic Anomaly: Mapping the effect and application of data corrective model

Popis výsledku v původním jazyce

South Atlantic Anomaly (SAA) affects the astronomical satellites and other spacecraft that orbit the Earth at several hundred kilometers altitude; these orbits take satellites through the anomaly periodically, exposing them to several minutes of strong radiation. The SAA-related frequency shift of Jason-1 DORIS oscillator is well known and the corresponding studies were published in the past. Recent analyses indicate that SPOT-5 DORIS oscillator is probably also affected, even if with lower influence. The first goal of this study is to obtain some evidence of the SAA effect on the SPOT-5 DORIS oscillator; this was carried out by analyzing frequency estimates and post-fit residuals. Furthermore, geographical grid maps are presented, displaying the estimated oscillator frequency drift and its time derivative. The second goal of the paper is to present an empirical DORIS observation corrective model, based on the application of the frequency drift derived from the previously created grid
