AKA: Satellite Probatoire d'Observation de la Terre. Status: Operational 1986. First Launch: 1986-02-22. Last Launch: 1993-09-26. Number: 3 . Gross mass: 1,869 kg (4,120 lb). Height: 3.50 m (11.40 ft). Span: 15.60 m (51.10 ft).
A single SPOT satellite provided complete coverage of the Earth every 26 days. Image products from SPOT were handled by a commercial entity, SPOT-Image Corp.
The spacecraft was 3-Axis stabilized to 0.1 deg using momentum wheels. A single solar array generated 1000 W (BOL) power. Downlink at 8 GHz and 2 x 25 Mbps. A hydrazine propulsion system provided orbit maintenance.
The HRV (High Resolution Visible) imaging payload provided 20 meter resolution multispectral imagery and 10 meter panchromatic imagery using push-broom sensors. HRV covered the following spectral bands: 0.5 - 0.59 � m, 0.61 - 0.68 � m, 0.79 - 0.89 �m; in addition to the panchromatic band: 0.51 - 0.73 � m. The field of view was 4.13 deg in both modes (multispectral and panchromatic) with 3000 pixels per multispectral line and 6000 pixels per panchromatic line. The observed strip was 60 km wide (swath width). On-board recorder capacity was 22 minutes for both modes. The HRV mass was 250 kg. The spacecraft carried two identical HRVs to provide a total of 117 km swath (with 3 km overlap).
