VNREDSat-1 (short for Vietnam Natural Resources, Environment and Disaster Monitoring Satellite, also VNREDSat-1A)[2] is the first optical Earth Observing satellite of Vietnam; its primary mission is to monitor and study the effects of climate change, predict and take measures to prevent natural disasters, and optimise the management of Vietnam's natural resources.[3]
Satellite
[edit | edit source]The VNREDSat-1 was built in Toulouse by EADS Astrium. During the project 15 Vietnamese engineers were integrated and trained by the Astrium team. The VNREDSat-1 system is based on the Astrium operational AstroSat100 satellite, used for the SSOT programme developed with Chile or the ALSAT-2 satellite system developed with Algeria. The 120 kg satellite will image at 2.5 m in panchromatic mode and 10 m in multi-spectral mode (four bands) with a 17.5 km swath, and will orbit at 600–700 km in a Sun-synchronous orbit.[4]
Launch
[edit | edit source]The satellite was launched from ELV at the Guiana Space Centre by the Vega VV02 rocket at 02:06:31 UTC on 7 May 2013 together with the PROBA-V and ESTCube-1 satellites.[5][6]
