SSTL’s UK-DMC2 satellite has successfully completed pre-launch tests and is integrated with a Dnepr launch vehicle at the Baikonur Cosmodrome in readiness for launch on Wednesday, 29th July 2009 at 18:46 UTC, 19:46 BST.
The new satellite will be operated by subsidiary company DMCii to provide an enhanced imaging capability and operational service to the Disaster Monitoring Constellation. UK-DMC2 has a number of enhancements over previous DMC spacecraft contributing to SSTL’s continuing evolutionary design approach.
The satellite is also being used as a test bed for new technologies and is supporting a BNSC sponsored school science experiment called POISE.
UK-DMC2 carries a higher resolution optical payload which will provide 22m ground sample distance images, compared with 32m GSD on the four operational satellites currently in the constellation. The 22m imagery has twice the data density of the 32m imagery without loss of Signal to Noise Ratio and maintains the ultra-wide 600+km swath.
The satellite carries two high-speed X-band transmitters that will both operate at 20Mbps or 80Mbps. This will enable the satellite to download images up to 10 times faster than previous DMC spacecraft. Storage capacity has increased from 1 to 1.5 GByte on the first generation of DMC spacecraft up to 12 GByte on UK-DMC2.
