NavCom's RT-3010S geodetic quality RTK GPS sensor provides high performance in a robust cost effective package. This fully integrated solution with 64MB of internal memory is ideally suited as a pole mounted RTK rover or a tripod mounted RTK base station for rapid centimeter-level accuracy.

Applications

The highly integrated RT-3010S solution is designed for productivity with minimal setup time. Two removable, rechargeable batteries provide more than 8 hours RTK performance to get you through a full day of surveying without the need to carry spare batteries. The housing is rugged and waterproof, designed to survive a 2m-pole drop and can survive temporary immersion in water. The RT-3010S supports high precision survey applications such as construction stakeout, boundary surveys, machine control, high-order control surveys, and topographic surveys. The centimeter-level accuracy is achieved by computing an independent solution at each epoch on a real GPS measurement. There is no interpolation at the rover, so you see the full dynamic picture.

Benefits

The RT-3010S receiver uses our NCT-2000D GPS engine, which incorporates our patented interference suppression and multi-path mitigation, geodetic quality measurements, and up to 50Hz raw data rate. With a signal-to-noise ratio advantage over competing technology, the user benefits from improved real-time positioning with instantaneous centimeter-level accuracy.

The antenna uses a dipole element with integral ground plane. Similar to a much larger choke ring antenna element, this new antenna provides excellent phase center stability.

The RTK algorithm developed by NavCom provides fast initialization and the NCT ultra compact binary data format for RTK ensures robust data throughput on the built-in spread spectrum radio. The sensor can utilize RTCM and CMR data streams from other base stations to minimize base rover separation. Each RT-3010S can be used as either a Base or a Rover to meet your changing needs as the survey progresses.

For GIS applications, your base station can be used as another rover. The two onboard WAAS/EGNOS channels, NavCom's enhanced SBAS algorithm and dual frequency GPS typically provide half-meter real-time accuracy.

Flexible Interface

The RT-3010S receiver is easily configured by the provided Windows®-based utility program. For system integrators needing maximum flexibility, the NCT binary user interface allows complete command and control of the GPS receiver and spread spectrum radio, thus enabling customization of the interface and receiver operation.
