Preferred term

SPOT-6  

Definition

  • 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 Satellite control centre Astrium Satellite – Toulouse (France) (en)
