  skos:definition """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.
