Alsat-1 still going strong

Alsat-1, the first SSTL satellite of the Disaster Monitoring Constellation (DMC) and the catalyst of Algeria’s fledgling space programme, remains healthy and fully operational after its sixth year in orbit.

Now, having exceeded its original 5 year schedule, Alsat-1 is more than 12 months into extended mission. The satellite engineers say that this remarkable extension was mainly accomplished through careful battery management.

Alsat-1 was not only the first DMC satellite, but also the first spacecraft to carry a Line Scan Imager. As such, SSTL is particularly delighted about this recent achievement. Its tasks have included responding to forest fires in Algeria and contributing to worldwide disaster response under the International Charter: Space and Major Disasters.

The Earth-Observation (EO) satellite is still providing imagery to the Algerian CNTS team (Centre National des Techniques Spatiales of Algeria) on a regular basis, although at a reduced capacity in order to further extend the battery life.

Alsat-1 carries an optical imaging payload developed by SSTL to provide 32m ground resolution with an exceptionally wide swath width of over 640 km allowing it to image an unparalleled area in each pass. CNTS is distributing the data to other Algerian institutions, which are using it for pollution monitoring, cartography and petrology applications.
