The main function of a GPS receiver is to lock onto satellites, to track them and to take accurate measurements. The merits that distinguish one receiver from others are how well it can track satellites under all environmental conditions and dynamics. Especially in today’s world with increasing communication systems that utilize the ‘sky’, and increasing urbanization, the practical use of GPS can be obstructed in many ways.

The more satellites you track, the faster and more reliable you work.

Topcon offers the use of not only the American based GPS satellites, but also the option for additional use of the Russian equivalent GLONASS. Although the GLONASS system has currently less satellites available than the GPS system, the additional use can give me just the extra I need in order to be able to work and achieve the accuracy I require.
