Data pubblicazione: | 2021 | Rivista: | ADVANCES IN SPACE RESEARCH | Numero: | 67 | Fascicolo: | 11 | Da pagina:: | 3793 | Abstract: | PROBA-3 is a space mission of the European Space Agency that will test, and validate metrology and control systems for autonomous formation flying of two independent satellites. PROBA-3 will operate in a High Elliptic Orbit and when approaching the apogee at 6·10<SUP>4</SUP> Km, the two spacecraft will align to realize a giant externally occulted coronagraph named ASPIICS, with the telescope on one satellite and the external occulter on the other one, at inter-satellite distance of 144.3 m. The formation will be maintained over 6 hrs across the apogee transit and during this time different validation operations will be performed to confirm the effectiveness of the formation flying metrology concept, the metrology control systems and algorithms, and the spacecraft manoeuvring. The observation of the Sun's Corona in the field of view [1.08;3.0]R<SUB>Sun</SUB> will represent the scientific tool to confirm the formation flying alignment. In this paper, we review the mission concept and we describe the Shadow Position Sensors (SPS), one of the metrological systems designed to provide high accuracy (sub-millimetre level) absolute and relative alignment measurement of the formation flying. The metrology algorithm developed to convert the SPS measurements in lateral and longitudinal movement estimation is also described and the measurement budget summarized. | URI: | http://hdl.handle.net/20.500.12386/31752 | URL: | https://www.sciencedirect.com/science/article/pii/S0273117720305147?via%3Dihub https://api.elsevier.com/content/abstract/scopus_id/85091509693 |
