  skos:definition """SPOT (Satellite Probatoire d'Observation de la Terre) is the
French government sponsored civil Earth observation program,
with support from Belgium and Sweden. A single SPOT satellite
provides complete coverage of the Earth every 26 days. Image
products from SPOT are handled by a commercial entity,
SPOT-Image Corp.

Spacecraft:

3-Axis stabilized. Single 5-panel solar array, each panel is 2.6
x 1.9 m. Hydrazine propulsion system provides orbit maintenance.

Payload:

Two HRVIR (High Resolution Visible - Infrared) pushbrrom imaging
instruments are carried. HRVIR is derived from the HRV
instruments on SPOT 1-3. This system will provide 10 m
resolution in the panchromatic band and 20 m resolution in the
multispectral bands. HRVIR includes a new medium IR channel to
support vegetation analysis and harvest forecasting. The HRVIRs
are steerable to within 27 deg off-nadir. Each HRVIR has a swath
width of 60 km. The Vegetation Monitoring instrument has 1 km
resolution in the same bands as the HRVIR. PASTEL optical link
terminal supports laser crosslink experiments. DORIS (Doppler
Orbitography and Radiopositioning Integrated by Satellite)
precision orbit determination system.
