LEGACY - E

GNSS Receiver With a Legacy-E GNSS receiver, fast and accurate solutions don’t rely on when or where you’re working, or how much time have. It has the world’s most advanced GNSS receiving technology built-in, ready to work where others won’t. Legacy-E contains our Eurocard format board. It is password upgradeable from single frequency GPS to dual frequency GPS+GLONASS. The box size is 240 x 110 x 35 mm. Click here to download product Data Sheet. All the Legacies have no antenna integrated inside. They give you the flexibility to use LegAnt, RegAnt or any other antenna. The cable connecting Legacy to the GPS antenna can be up to 30 meters long. For longer lengths, one line amplifier should be used for every additional 30 meters. Line amplifiers should be ordered separately.

At its core is our Paradigm® chip featuring 40 universal super channels that can each track all signals of either L1 or L2 GPS frequencies. It incorporates our new innovations in signal processing, multipath mitigation and co-op tracking, making Topcon GNSS the best in the field for under-canopy and low signal strength reception.

Our unique Cinderella feature activates GPS L1+L2 and GLONASS reception every other Tuesday for 24 hours so you can experience the real power of Topcon GNSS. Permanently activating these frequencies and other options is easy with simple password commands entered via a PC. Options can even be added on a pay-per-use basis—only when you need it. The MINimum INTERface keeps operation very simple. Just two function keys and two 3-color LED’s are all that’s needed to record data and check status. Up to four serial ports lets Legacy-E work with a variety of accessories in all types of configurations. Topcon offers a full line of antennas, radios, post-processing software and all the other accessories and hardware that will help ensure maximum productivity and accuracy. Powerful, simple, versatile. Topcon Legacy-E—no ordinary GPS receiver.

Specifications are subject to change without notice. Performance specifications assume a minimum of 6 6 GPS or 7 GPS/GLONASS satellites above 15 degrees in elevation and adherence to procedures recommended by TPS in the appropriate manuals. In areas of high multipath, during periods of high PDOP and during periods of high Ionospheric activity performance may be degraded. Robust checking procedures are highly recommended in areas of extreme multipath or under dense foliage.
*Cinderella feature activates GPS L2 and GLONASS reception at GPS midnight every other Tuesday for 24 hours.
