RTD-Pro

RTD Rover Technical Specifications

RTD Rover Example Configurations

Applications
Surveying, precise GIS, precision agriculture, machine control, vehicle tracking, harbor navigation, autonomous robotics, fleet and product tracking.

Modes
All modes support real-time initialization-free (instantaneous), wide-area positioning, including ionosphere correction. Troposphere delay also estimated Epoch-by-Epoch™. Single-base mode - single baseline operations using RTCM. Dual-base mode - Precisise Instantaneous Network (PIN) positioning with two base stations using RTCM. RTD Smart Client mode - PIN-positioning with two base stations from a reference network managed by Geodetics RTD Pro server. Short baseline option (< 5k).

Communications
Supports RS-232, Bluetooth, TCP/IP communications with rover receiver, up to two reference (base) stations.

Output
Solutions in NMEA GGA and GSV delivered via RS-232, Bluetooth, TCP/IP to external applications running on the same or separate device.

User Interface
Intuitive, guides the user through the setup process.

Sensors
Leica dual-frequency receivers (CRS1000, System 500 series, GPS1200 series). Ashtech dual-frequency receivers (Z series). Trimble dual-frequency receivers (4000SSi, 4000, SSE, 4700, 4800, 5700, NetRS). Topcon receivers, Novatel OEM4 receivers.

Data Logging
Position solutions and raw field receiver data. Diagnostic displays and logging.

Algorithm
Proprietary Real-Time Network Analysis (RNA) module with Geodetics' Epoch-by-Epoch

Solutions
Independent position computation at each epoch in baseline and network modes.

Precision*
Single epoch precision* +- [10mm - 0.2mm/km] horizontal 3-5 times less precise in vertical (1 standard deviation). Average multiple epochs for increased precision and reliability.

Range*
Up to 50 km in multiple-base station modes.

Hardware Requirements
Processor: 400 MHz. Strong Arm, X Scale
Memory: 128 MB minimum
OS: Microsoft Windows CE .NET

* Accuracy and range are dependent upon GPS satellite system performance, ionospheric conditions, and other factors.

Single-base mode: Communications between RTD Rover and the reference receiver made via TCP/IP over the Internet. Communications between RTD Rover and the local receiver are made via Bluetooth. Communications between RTD Rover and the data logger are made via Bluetooth.

Dual-base mode: RTD Rover running on data logger simultaneously with third party application (e.g. Carlson SurvCE) making use of RTD Rover computed solutions. Communications between RTD Rover and reference receiver 1 made via TCP/IP over the Internet. Communications between RTD Rover and reference receiver 2 made via an RS-232 connection to one end of a wireless radio pair. The other end of the pair is connected via RS-232 to reference receiver 2. Communications between RTD Rover and the local receiver made via RS-232 connection.
