The
3030 kg (6666 lbm) Satellite Probatoire de l'Observation de la
Terre (SPOT) spacecraft was built by Astrium, with
payloads provided by Alcatel Space. The satellite has a 5 year
design life, and will have a beginning of life power of 2.350 kW.

SPOT satellites follow
an orbit which is sunsynchronous, circular and phased, enabling
them to overfly any given point always at the same local time. The
time of passage of the SPOT satellites above any given region is
maintained to within plus or minus 15 minutes, and they retrace
their route with an accuracy of plus or minus three kilometers at
the equator. It takes 26 days for a SPOT satellite to complete 369
orbits and return to its original position with respect to Earth.
The Spot 5 spectral
bands will be:
| Band |
Spectral range
(µm) |
Spatial resolution
(m) |
| B1 (Green) |
.500 - .590 |
10 |
| B2 (Red) |
.610 - .680 |
10 |
| B3 (Near IR) |
.790 - .890 |
10 |
| SWIR (MIR) |
1.58 - 1.75 |
20 |
The panchromatic band
will use 0.51-0.73 µm. Spatial resolutions will be
improved within the limits of technical feasibility as the field
width of each instrument will be also kept identical. The
high-resolution panchromatic mode will be 5m and 2.5m and the
multispectral mode (B1, B2, B3) 10m.
Spot Image's main shareholders are
CNES (35%), private industrial groups, including Astrium (formerly
Matra Marconi Space) which is prime contractor for the SPOT satellites (23%), the French National Geographic Institute (IGN -
10%), and shares held by government and private entities in
Belgium, Sweden and Italy (11%).
