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.
Because of the unique Topcon technologies like the In Band Interference/ Jamming suppression, the co-op tracking and multipath reduction solutions, you will find that all Topcon receivers initialize and re-acquire faster than you’ve ever experienced, and especially under tough conditions with limited skies. Add to that the combined use of GLONASS and you will see that Topcon receivers allow you to measure points that were not accessible before, and with high accuracies!
Key Features:
Leading Technology
The specification’s we have set for our receivers underline the unique technology that forms the core. When working with a Legacy, these specifications immediately materialize in benefits like super fast initializations, highest accuracy and most important of all, highest performance under conditions you’ve not been able to work before!
GPS+ ... Not just GPS
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 then the GPS system, the additional use can give you just the extra you need in order to be able to work and achieve the accuracy required where others will have to take a coffee break!
Topcon’s Legacy series offer 40 universal superchannels as a standard. They all can track either L1 or L2 GPS or GLONASS, so 20 satellites (the maximum available at any time) can be tracked at the same time without any channel switching! All channels can also be used for INMARSAT or WAAS/EGNOS systems, and for possible other future satellite based systems. Each of these 40 channels houses 4 correlators, that function as independent channels during initialization. In this way, each millisecond, 160 channels are searched for satellite info, giving initialization & start up times that are upto 13 times faster then for instance regular 12 channel receivers!
