An international programme using eight low-cost microsatellites that form a network that provide a daily global imaging capability at 30–40 m resolution in 3–4 spectral bands to assist in rapid-response disaster monitoring and mitigation. The spacecraft were constructed by Surrey Satellite Technology Ltd., UK, and are operated on behalf of the Algerian, Nigerian, Turkish, British, and Chinese governments.
