SPOT 4 satellite operations have been resumed after orbital parameters corrections. Starting on February 6 the space vehicle has been performing long-swath imaging in direct access mode of the Russian territory on all passes over the country.
Regular imaging and data transmission from SPOT 4 satellite was suspended on December 7, 2009 for correction of orbital parameters. It was required to perform an orbital maneuver of SPOT 4 due to the approach of two operational satellites SPOT 4 and SPOT 5 flying the similar sun-synchronous orbits in one and the same plane. Further approach of two space vehicles could bring to lower efficiency in getting SPOT 4/5 data by the ground stations. The orbital position of SPOT 4 satellite has been successfully changed, with the phase angle between SPOT 4 and 5 SPOT 5 increased from 70 to 166 degrees.
SPOT 4 satellite was launched in 1998 (expected lifespan is 5 years) for Earth remote sensing with the resolution of 10 m in PAN and 20 m in MSS modes and the swath of 60 km. The data from SPOT 4 satellite have been received directly to the network of UniScan ground receiving stations in open access mode since 2007 according to the agreement signed between ScanEx RDC and Spot Image (France). By now it allowed creating a complete cloud-free coverage of all the Russian territory.
ScanEx RDC continues to accept orders for imaging of the areas of interest due to the resumption of the SPOT 4 satellite operation over the phone +7(495)739-73-85 or by e-mail sales@scanex.ru.

Adopting Cloud computing can save money, but good governance is essential to manage the risk argues Mike Small
