A new generation of Global Positioning System (GPS) satellites, called Block IIR-M, has been launched since December of 2005. These satellites are part of the modernization effort that the GPS is undergoing. The signals transmitted by these satellites contain a new civilian code superimposed on the L2 carrier, called the L2C code. Research into the characteristics of the L2C code is based on an International GNSS Service (IGS) L2C dedicated Test Network. This network is composed of both existing stations as well as newly established ones with receivers capable of tracking the L2C signal. The IGS L2C Test Network is composed only of Trimble receivers.
