Spacemetric has delivered a Keystone System for the KazSTSat mission being developed jointly by Surrey Satellite Technology Limited (SSTL) and Ghalam LLC of Kazakhstan. The new mission uses the new SSTL-X50 platform and builds upon heritage from the Disaster Monitoring Constellation (DMC). It includes an updated wide-swath instrument with six spectral bands and a resolution of 17.5 metres, along with several experimental payloads.
The SSTL SLIM6 sensor has been modified for the KazSTSat mission to specifications defined by DMC International Imaging Ltd (DMCii), the commercial distributor of imagery from the DMC satellites. This medium-resolution imager now provides Coastal Blue, Blue and Red-Edge channels in addition to the Red, Green and Near Infra-Red channels of the previous DMC missions. Spacemetric is responsible for physical sensor modelling of the new instrument and has incorporated this capability into the Keystone software. After launch, the sensor parameters will be refined through an in-orbit calibration
“This is a second mission for Kazakhstan that uses our Keystone software and we are thrilled to again be helping SSTL’s customers achieve their ambitions in Earth observation” commented Mikael Stern, Spacemetric’s CEO. Previously Spacemetric has delivered a ground processing and archive system for the KazEOSat-2 mission, a satellite based closely on RapidEye and developed for Kazakhstan Gharysh Sapary (KGS). Keystone operator training took place at KGS early in October 2015.
