SPOT 5 Ready for Action 07.15.2002
Tests performed during in-orbit checkout have shown that:
- The satellite, ground telemetry and command systems, and passenger instruments are functioning perfectly and system availability is excellent.
- Geometric and radiometric quality of images from the two HRG (high-resolution geometric) instruments and the HRS (high-resolution stereoscopic) instrument is excellent, exceeding specifications.
In-orbit checkout of the VEGETATION instrument will be completed in November 2002. Performance so far is excellent.
SPOT 5 offers unrivaled acquisition capability with its HRG instruments, offering a wide imaging swath of 60 km x 60 km or 60 km x 120 km at a resolution of 2.5 meters, and its HRS instrument, which supports operational production of high-accuracy digital elevation models (DEMs).
The other satellites in the SPOT constellation - SPOT 1, SPOT 2 and SPOT 4 - are still functioning, with SPOT 1 as an on-orbit spare ready to resume operation if necessary.
