About SPOT 1
SPOT 1 (Satellite pour l'Observation de la Terre) was a commercial Earth-imaging satellite from CNES (Centre National D’Etudes Spatiales), the French Space Agency. It was launched on 22 February 1986 and ceased operations in November 2003. SPOT 1, 2 and 3 were identical.

SPOT 1 Objectives
SPOT 1, supplying high-resolution, wide-area optical imagery, was designed to improve the knowledge and management of Earth's resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena.
SPOT 1 Instruments
High-Resolution Visible (HRV)
Two identical HRV (High Resolution Visible) imaging instruments on SPOT 1 provided data at 10 metre spatial resolution and were able to operate in two modes: Panchromatic and 20 metre (Multispectral mode) with a swath of 60 km simultaneously or individually.
The HRV had an oblique viewing capability of 27° on each side of the local vertical. The swath was 117 km2 if both sensors were used simultaneously with a 3 km2 overlap.
