SPOT 4 opened the 2010 imaging season
SPOT 4 satellite operations have been resumed after orbital parameters corrections. Regular imaging and data transmission from SPOT 4 satellite was suspended in December 2009 for correction of orbital parameters. An orbital manoeuvre of SPOT 4 was required 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. 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.
