Topcon Expands GPS+, Unveils All-Inclusive GNSS Receiver

Topcon1

Livermore, CA - Topcon has introduced a new GR-3 system, which according to company is the world's first all-inclusive RTK GNSS satellite receiver for all existing and planned satellite constellations. Topcon is believed to have pioneered the application of GNSS reception, and for the last six years has been the industry's single source for dual-constellation operation with its GPS+ technology. Its GPS+GLONASS receivers have provided unmatched signal acquisition, uptime, and accuracy in diverse terrain and conditions.

In 2005, Topcon introduced the G3 chip, which can capture signals from all three satellite-positioning systems--GPS, GLONASS, and the planned European Union's Galileo system--providing enhanced GPS+ technology for the new GR-3. The GR-3 also sets a new standard for rugged construction and unparalleled durability: it is designed to withstand a fall on a range pole (two-meters) and comes with a "bulletproof" warranty to back it up.

GR-3 has 72 universal channels that can track up to 36 satellites simultaneously...all positioning satellites, generating any signal, any time, 24/7. Topcon engineers developed the G3 chip to receive all existing signals, plus all signals from planned satellite launches in the foreseeable future.

The GR-3 boasts a completely integrated, cable-free base and rover design for use in a constantly expanding range of applications. In addition to Paradigm G3 technology, the sleek and rugged unit features:

  • Two-watt 915+ internal spread-spectrum radio that provides reliable and interference-free RTK communication at maximum distance from the base to rover unit. (915 MHz spread spectrum radio technology is not approved for use in Europe or Asia.)
  • Optional internal GSM/GPRS SIM card modem for cellular connectivity.
  • Ergonomic design that includes a "quick-snap" pole mount, reducing the likelihood of damage while affixing it to or removing it from the pole.
  • Dual, "hot-swappable" battery packs that give GR-3 an operation time of more than 12 hours.
  • An additional battery pack that utilizes off-the-shelf AA batteries.
  • Dual-function design--each unit can be a base or rover.
