Constellations

Small satellite constellations are financially viable, enable rapid revisit imaging and provide flexibility for replenishing space assets for data continuity. SSTL conceived the innovative and uniqe Disaster Monitoring Constellation (DMC), the first Earth observation constellation of low cost small satellites providing daily images for applications including global disaster monitoring.

The DMC provides:

Daily revisit
Multi-spectral imagery (Landsat-ETM 2, 3 & 4)
Wide swath (600km )
32m GSD resolution
4m PAN

SSTL has also supplied the platforms for the 5-satellite RapidEye constellation which is due for launch in 2008. RapidEye is a small satellite commercial mission being developed by MacDonald Dettwiler & Associates (MDA). This unique system will enable unprecedented global monitoring of the Earth’s surface. The mission will provide rapid delivery of land information products and services to the agricultural industry for crop monitoring and mapping, yield predictions and natural disaster assessment.
