Trimble R-Track technology in the Trimble R8 GNSS system and Trimble NetR5 Reference Station also supports GLONASS L1/L2 signals, the GNSS owned by the Russian Federation Government. In 2004 the United States and the Russian Federation issued a joint statement on cooperation, with the objective of maintaining and promoting interoperability between their two systems.
Trimble incorporates new technology when confident that it will provide surveying professionals with real field and business benefits. As evidence of this commitment to our customers, Trimble R-Track technology in the Trimble R8 GNSS now takes advantage of all currently available and imminent GNSS signals, including the new L2C signal and coming L5 band of GPS Modernization, plus GLONASS L1/L2. Trimble R-Track technology provides outstanding quality control in computing solutions using all available signals.

Don't Look Back
Despite the collapse of Galileo's original plan for funding...the European Union's public-private partnership (PPP)...the Galileo project is still moving forward. To keep the project moving, the most likely avenue of funding will be through the public sector. For a thoughtful discussion about the continued importance of the Galileo project, see the article 'Don't Look Back' by the editor of Inside GNSS. To read more, download the article.
One Year in Space for Galileo In-Orbit Validation Element
The GIOVE-A, the first Galileo satellite, has now been in orbit for one year. This pilot satellite is a key element of the Galileo program, bringing the Galileo frequencies into use, testing new critical technologies and characterizing the medium Earth orbit environment.
