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.
