OPTSAT-3000 ( OPTical SATellite-3000 [4] ), or SHALOM ( Spaceborne Hyperspectral Applicative Land and Ocean Mission [3] ) is an Italian Earth observation and reconnaissance satellite developed and built by Israel Aerospace Industries and operated by the Italian Ministry 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 the TecSAR-1 satellite. [3]

Design [ edit ]

Satellite bus [ edit ]

OPTSAT-3000 is based upon the bus of the Israeli reconnaissance satellite TecSAR-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 ]

Main article: Vega flight VV10

OPTSAT-3000 launched from Guiana Space Centre ELV , French Guiana , on board a Vega rocket. It was launched to a Sun-synchronous low Earth orbit 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.
