NIR Lasers in Chile Measure Satellites

Facebook X LinkedIn Email
DARMSTADT, Germany, Dec. 30, 2011 — The first laser measurements of Galileo operational satellites in orbit have been made from Chile. The Transportable Integrated Geodetic Observatory (TIGO) performed the laser ranging at an altitude of 23,230 km using a near-infrared laser beam. TIGO performed the world's first laser ranging of the first Galileo satellite on Nov. 27, 2011. TIGO was put in place to fill gaps in various types of worldwide geodetic measurements. (Images: ESA/TIGO — BKG/UdeC/IGM) The laser ranging was achieved on Nov. 27 at 2:45 GMT, while the second measurement happened two days later at...Read full article
