| SPOT receiving stations operate on 8 GHz (X-band). This networks comprises two types of stations:
- two main stations at Toulouse and Kiruna. These stations are capable of receiving the telemetry previously recorded on the on-board recorders or directly within their visibility circle of approximatively 2500 km radius centred on the stations. Hence, they have access to imagery of any part of the globe.
- 20 direct receiving stations (DRS) which can only receive telemetry within their visibility circle. each DRS effectively manages its own visibility aone according to the satellite resources allocated by Spot Image. For each allocated pass, the station operator specifies the imaging conditions through a dialogue with a front end computer (FCMS) situated in the Mission Control Centre. One of these Direct Receiving Station is located at CRISP, Singapore.
