SPOT-6/7
The SPOT twins operate in phased orbits and can revisit any point on the globe once per day. They deliver 1.5-meter high-resolution imagery across five spectral bands and can capture 6 million square kilometers per satellite per day.
- Daily acquisition capacity of 6 million km² per satellite.
- High-resolution products with five spectral bands
- Daily revisit, anywhere
About SPOT-6/7
With SPOT 6 and SPOT 7, Airbus Defence and Space (DS) not only secures mission continuity of its SPOT series, which has collected an archive of more than 30 million scenes since 1986. This new generation of optical satellites features technological improvements and advanced system performance that increase reactivity and acquisition capacity, as well as simplifying data access.
