SPOT 6 and SPOT 7: extending SPOT continuity to high-resolution, wide-swath imagery
SPOT 6 and SPOT 7: extending SPOT continuity to high-resolution, wide-swath imagery
-

SPOT 6 and SPOT 7 form a constellation of Earth-imaging satellites designed to provide continuity of high-resolution, wide-swath data up to 2023. Both satellites have drawn on technological and operational innovations conceived for the Pliades constellation.

SPOT 6&7 products: the right balance between high resolution and large-area coverage
-

Simplified standard product

  • Automatic orthoimage with location accuracy of 10 m CE90 using Reference3D

    - green (0.530 m 0.590 m)
    - red (0.625 m 0.695 m)
    - near-infrared (0.760 m 0.890 m)
  • Pan-sharpened: 1.5-m colour merge combining panchromatic and four multispectral bands
  • Imaging swath: 60 km at nadir
  • Format: JPEG 2000

Advanced products

  • 120 km x 120 km bi-strip or 60 km x 180 km tri-strip mapping in a single pass and delivery of mosaic

A new funding model for the remote-sensing industry
-

EADS Astrium took the decision to build the SPOT 6 and SPOT 7 constellation of satellites in 2009 to maintain continuity of high-resolution data collection and distribution provided by the SPOT series.
Spot Image, a subsidiary of Astrium, is funding the satellites alone and owns the data and system (satellites and ground segments). It is also the commercial satellite operator. This is the first time in the remote-sensing industry that satellite development costs have been funded with entirely private funds.
