French earth land resources satellite. Trench earth land resources satellite. SPOT was the French government sponsored civil Earth observation program. A single SPOT satellite provided complete coverage of the Earth every 26 days. Earth Observing satellite built by Astrium for Spot Image, France. Launched 2002. Used the SPOT Mk.3 bus.

AKA: Satellite Probatoire d'Observation de la Terre. Status: Operational 2002. First Launch: 2002-05-04. Last Launch: 2012-09-17. Number: 3 . Gross mass: 3,000 kg (6,600 lb). Unfuelled mass: 2,850 kg (6,280 lb).

The system provided 5 m resolution in the panchromatic band and 10 m resolution in the multispectral bands.

SPOT 5A and 5B were the next generation of this series. Additional program support came from Belgium and Sweden. Image products from SPOT were handled by a commercial entity, SPOT-Image Corp. The spacecraft was 3-axis stabilized, with a 150 Mbps downlink rate. The payload included the HRG (High Resolution Geometry) instrument for multispectral imaging of the earth's surface. Each spacecraft carried three HRGs, one looking forward, one looking down, and one looking aft.

Total SPOT budget was $ 5 billion. Original budget was $ 1150 million for 2 units; this was cut to $ 680 million for 1 unit in June 1986. Alcatel's payload contract for $ 92.6 million was signed on 2 February 1995.
