OPTSAT-3000(OPTical SATellite-3000[4]), orSHALOM(Spaceborne Hyperspectral Applicative Land and Ocean Mission[3]) is an ItalianEarth observationandreconnaissance satellitedeveloped and built byIsrael Aerospace Industriesand operated by the ItalianMinistry of Defence.Launched on August 2, 2017, it has an expected service life of at least 7 years. It is based on the design of theTecSAR-1satellite.[3]
Design[edit]
Satellite bus[edit]
OPTSAT-3000 is based upon the bus of the Israeli reconnaissance satelliteTecSAR-1,but is modified for optical instruments. It has a launch mass of 368 kg (811 lb) and dimensions of 4.58 × 3.35 × 1.20 m (15.0 × 11.0 × 3.9 ft) when its two solar arrays are deployed.[3]
Imaging system[edit]
OPTSAT-3000 has a high-resolution optical imaging system known as Jupiter, which is able to deliver panchromatic images with a resolution of 0.5 m (1 ft 8 in) while operating the multispectral channel at the same time. These imaging detectors, combined with a 70 cm (28 in) telescope from an altitude of almost 600 km (370 mi), allows OPTSAT-3000 to cover a ground track 15 km (9.3 mi) wide.[3][4]
Launch[edit]
OPTSAT-3000 launched fromGuiana Space CentreELV,French Guiana,on board aVegarocket. It was launched to aSun-synchronouslow Earthorbit with an apoapsis of 501.8 km (311.8 mi), a periapsis of 474.1 km (294.6 mi) and an inclination of 97.2°, allowing it to cover much of the world.[3][4][5]
