GIOVE-A laser ranging campaign successful

3 October 2006

Fourteen laser ranging stations participated in a campaign to track ESA’s GIOVE-A satellite during the spring and summer of 2006, providing invaluable data for the characterisation of the satellite’s on-board clock. The campaign was coordinated by the International Laser Ranging Service (ILRS) and the GIOVE Processing Centre at ESA-ESTEC.

GIOVE-A, developed by Surrey Satellite Technology Ltd (UK), was launched from Baikonur Cosmodrome on 28 December 2005 and placed into a medium Earth orbit with an altitude of 23 260 km. Carrying a payload consisting of rubidium clocks, signal generation units and a phase array of individual L-band antenna elements, GIOVE-A started broadcasting Galileo signals on 12 January, securing the frequencies allocated by the International Telecommunications Union for the Galileo system.
