Laser ranging

The Transportable Integrated Geodetic Observatory, TIGO, in Concepción, Chile, performed the world's first laser ranging of the first Galileo satellite on 27 November 2011.

TIGO is owned by the German Bundesamt für Kartographie und Geodäsie (BKG) and has been operating jointly with the Universidad de Concepción (UdeC) and the Chilean Instituto Geográfico Militar (IGM) since 2002, filling gaps in various types of worldwide geodetic measurements.
