Earth observation optical satellite system for Vietnam to create a space infrastructure enabling the country to better monitor and study the effects of climate change, predict and take measures to prevent natural disasters, and optimise the management of its natural resources.
The VNREDSat-1 programme, awarded to Airbus Defence and Space in 2010, is the result of an initiative by the Vietnamese government to create a space infrastructure enabling the country to better monitor and study the effects of climate change, predict and take measures to prevent natural disasters, and optimise the management of its natural resources. The contract between Airbus Defence and Space and VAST covers the development, manufacture and launch of an Earth observation optical satellite system.
The VNREDSat-1 system comprises an optical satellite capable of capturing images with a resolution of 2.5 metres, the associated ground control, image receiving and processing stations, and a co-operation and training programme for Vietnamese engineers.
The satellite has been built at Airbus Defence and Space's Toulouse site. During the project 15 Vietnamese engineers were integrated and trained by the Airbus Defence and Space team. The VNREDSat-1 system is based on the Airbus Defence and Space operational AstroSat100 satellite, used for the SSOT programme developed with Chile or the ALSAT-2 satellite system developed with Algeria.
VNREDSat-1 was placed in orbit on 6 May 2013 aboard a Vega rocket from the European Space Centre in Kourou, French Guiana.
The 130kg satellite will image at 2.5m in panchromatic mode and 10 m in multi-spectral mode (four bands) with a 17.5km swath, and will orbit at 600–700km in a sun synchronous orbit.
