The SPOT (Systeme Pour l'Observation de la Terre) series are French satellites. SPOT-1 is no longer transmitting image data, so there are currently three SPOTs. SPOT-2 and -3 each carry two high-resolution visible (HRV) sensors for a total swath width of 117 km. SPOT-4 carries two high-resolution visible-infrared (HRV-IR) sensors, which are similar to the previous HRVs. SPOT-5 carries a high spatial resolution version of the HRV-IR, the High Resolution Geometry (HRG). Also on SPOT-4 and -5 is a vegetation instrument with the same spectral bands as the HRV-IR, but with a 1-km spatial resolution. The HRVs and HRV-IRs are pointable, providing up to 27° off-nadir looks. This off-nadir viewing enables the acquisition of stereoscopic imagery. These satellites have a polar, circular, sun-synchronous 832-km orbit with a 26-day repeat cycle, with more frequent off-nadir views. These sensors can collect either multispectal (XS) or panchromatic (PAN) imagery.
