text: TECHNICAL FEATURES
With SPOT 6 and SPOT 7, Astrium not only secures mission continuity of the SPOT series, which has been
collecting an archive of more than 30 million of scenes since 1986: this new generation of optical satellites also
features technological improvements and advanced system performance that increase reactivity and
acquisition capacity as well as simplifying data access.

Space segment:
SPOT 6 and SPOT 7 will provide 1.5metre resolution products over broad areas until 2024.
Number of satellites 2
Launch periods
SPOT 6: September 12th, 2012
SPOT 7: June 30th, 2014
Design lifetime 10 years
Size Body: ~ 1.55 x 1.75 x 2.7 m
Solar array wingspan 5,4 m2
Launch mass 712 kg
Altitude 694 km
Onboard Storage 1 Tbits end of life (Solid State Mass Memory)

Orbital characteristics and viewing capability:
SPOT 6 and SPOT 7 missions are designed to achieve efficiently both collection of large coverage and collection
of individual targets that are possible thanks to the extreme agility of the satellite.
Orbit Sun-synchronous; 10:00 AM local time at descending node
Period 98.79 minutes
Cycle 26 days
Viewing angle Standard: +/- 30° in roll | Extended: +/- 45° in roll
Revisit
• 1 day with SPOT 6 and SPOT 7 operating simultaneously
• Between 1 and 3 days with only one satellite in operation (note 1)
Pointing agility
Control Moment Gyroscopes allowing quick maneuvers in all
directions for targeting several areas of interest on the same pass (30°
in 14s, including stabilization time)
Acquisition capacity Up to 6 million sq.km daily with SPOT 6 and SPOT 7 when operating
simultaneously
Nominal Imaging Mode 60km-swath strips oriented along North-South axis; up to 600km
length
Stereo capability Fore and aft mode; Single pass stereo and tri-stereo

Note1: Depends on the latitude of the area of interest

Instruments:
Optical system One instrument made of 2 identical Korsch telescopes, each with a 200
mm aperture, delivering the expected swath.
Detectors PAN array assembly: 28,000 pixels
MS array assembly: 4 x 7000 pixels
Spectral bands
Panchromatic: 0.450-0.745 µm
Blue: 0.450-0.520 µm
Green: 0.530-0.590 µm
Red: 0.625-0.695 µm
Near Infrared: 0.760-0.890 µm
The 5 bands are always acquired simultaneously.
Swath 60km at nadir
Dynamic range at acquisition 12 bits per pixel
Location accuracy specification
• 35m CE 90 without GCP within a 30° viewing angle cone
• 10m CE90 for Ortho products where Reference3D is available
Instrument telemetry link rate X-band channel - 300 Mbits/s

Ground segment:
Main receiving stations
• Toulouse (France)
• Kiruna (Sweden)
S-Band uplink stations
• Kiruna (Sweden)
• Inuvik (Canada)
Programming centre
Astrium GEO-Information Service – Toulouse (France)
Astrium GEO-Information Service – Chantilly VA (USA)
Production centre Astrium GEO-Information Service – Toulouse (France)
Tasking plans refresh frequency 6 times/day/satellite
Update of weather forecast 4 times/day – fully automatic process
