- The SPOT-1 (Satellite Pour l'Observation de la Terre) spacecraft was launched on February 22, 1986. SPOT-1 is an earth observation satellite with a greater ground resolution than that of the Landsat series satellites. The main applications for the images returned by the first SPOT mission are land-use studies, agriculture and forestry resources, mineral and oil resources, and cartography. The three-axis stabilized satellite operates in a circular sun-synchronous near-polar orbit for a design lifetime of 2 years. Orbital Characteristics- Orbital Period: 101.40 m Inclination: 98.70 degrees Eccentricity: 0.00101 Periapsis: 815.00 km Apoapsis: 829.60 km The spacecraft dimensions are 2 x 2 x 3.5 m and 15.60 m for the overall length of the deployed solar panel. SPOT-1 consists of two parts: (1) the bus, a standard multipurpose platform, and (2) the payload. The bus provides housekeeping information and an onboard computer. The payload is mounted on one of the side panels of the bus. SPOT-1 consists of two identical high-resolution visible (HRV) imaging instruments and a package comprising two magnetic-tape data recorders and a telemetry transmitter. The HRV imaging instrument observes in three spectral bands (in the visible and near infrared regions) with a ground resolution of 20 m, and/or in a broader spectral band (panchromatic black and white) with a ground resolution of 10 m. The pattern of successive ground tracks is repeated exactly at 26-day intervals. The SPOT-1 instrument package has the provision for off-nadir viewing which should be particularly useful for monitoring localized phenomena evolving on a relatively short timescale. SPOT-1, also, provides the capability for recording stereoscopic pairs of images of a given area during successive satellite passes. *NOTE-SPOT1 is used for technological experiments such as : refocusing, batteries, etc,... *NOTE-SPOT1 is no more used for commercial image acquisition.
