RT-3020 User Guide - Rev D Global Positioning System Selective availability (S/A code) was disabled on 2nd May 2000 at 04:05 UTC. The United States government has stated that present GPS users do so at their own risk. The US Government may at any time end or change operation of these satellites without warning. The U.S. Department of Commerce Limits Requirements state that all exportable GPS products contain performance limitations so that they cannot be used to threaten the security of the United States. Access to satellite measurements and navigation results will be limited from display and recordable output when predetermined values of velocity and altitude are exceeded. These threshold values are far in excess of the normal and expected operational parameters of the RT-3020 GPS sensor. Use of this Document This User Guide is intended to be used by someone familiar with the concepts of GPS and satellite surveying equipment. Note indicates additional information to make better use of the product. Indicates a caution, care, and/or safety situation. Warning indicates potentially harmful situations.

RT-3020 User Guide - Rev D Chapter 1 Introduction The RT-3020 GPS sensor delivers unmatched accuracy to the precise positioning community who need a cost-effective, high performance GPS sensor. This unique receiver can transmit or receive corrections via an onboard Spread Spectrum Radio (SSR). System Overview GPS Sensor The RT-3020 sensor consists of a 10-channel dual frequency precision GPS receiver with two additional channels for receiving Satellite Based Augmentation System (SBAS) signals. The sensor can output proprietary raw data as fast as 50Hz (optional) and Position Velocity Time (PVT) data as fast as 25Hz (optional) through two 115kbps serial ports. The RTK software provides fast initialization. Testing shows that the system resolves ambiguities at start-up or on reacquisition of satellites typically within two seconds. The RT-3020 has a built-in Spread Spectrum Radio providing an immediate solution for the system integrator and real time surveyor. Utilizing the built in radio for RTK measurements, the receivers communicate using NavCom’s highly efficient proprietary RTK format or other RTK formats, such as RTCM and CMR. Additionally, the receivers simultaneously accept corrections for DGPS (WAAS/EGNOS) assuring seamless position output. The RT-3020S is packaged for mobility. It can be used for construction stakeout, boundary surveys, high order control surveys and topographic surveys in rough 1-6
