Surveyor+ GNSS

Surveyor+ GNSS

New and Improved! The All-in-One Surveyor+ GNSS System — a dual frequency RTK GNSS receiver and field controller and can be purchased at a local Carlson dealer near you! Important qualities include:

*At a recent Connecticut Survey Association meeting, Michael Jiantonio of Superior Instruments made this observance: “I pointed out to customers asking about the Surveyor+ GPS that it is rated for the SAME ACCURACY as the other GPS that they were seeing in the room, but the others were selling for nearly twice the price. The look of surprise, and in some cases shock, made me realize that I needed to educate them that RTK equals 1 cm Hz accuracy.”

  • Accurate*
  • Affordable*
  • Rugged
  • Reliable

SCALE-ABLE: If you have the Carlson Surveyor+ data collector now or are thinking about purchasing one, you can add the RTK engine at anytime

VERSATILE: Network RTK, Base/Rover RTK and static capable

FLEXIBLE: Works with drivers for most all brands of total stations & robotics; get ability to localize the set-up and backsight

You’ll get all this and more with the Carlson Surveyor+ GNSS System:

  • Loaded with Carlson SurvCE — our field data collection software, works together with our office software for seamless integration from field to office and back. Carlson SurvCE works with all brands of survey equipment: conventional total stations, robotic total stations, and RTK GPS survey gear. Survey offices and survey departments throughout the US and the world are finding this obvious combination the most productive, straightforward survey solution for their field and office needs.
  • Network RTK Ready: Internal GSM SIM Card Enabled Modem
  • Internal Wi-Fi & Bluetooth® Connectivity
  • System provides 8-plus hours total operation
  • Includes all of the specifications of the Carlson Surveyor+!

Carlson Review


Donald Poole, PLS, reviews the Carlson Surveyor+ GNSS system in POB Magazine. He concludes, “The system is made by surveyors for surveyors. If you are in the market for GPS, definitely put this on your demonstration list and check with your dealer.” Read more.

Dual Constellation for Enhanced Positioning (Legacy)

Surveyor+ GNSS

  • The GPS-702-GG uses the L1 and L2 frequencies
  • Antenna offers combined GPS+ GLONASS signal reception
  • Customers can use the same antenna for GPS-only or dual constellation applications, resulting in increased flexibility and reduced equipment costs
  • Patented Pinwheel™ technology provides superior multipath rejection in a compact and lightweight antenna
Stable Phase Center
  • For added reliability, the antenna’s phase center remains constant as the azimuth and elevation angle of satellites change with signal reception unaffected by the rotation of the antenna or satellite elevation.
  • In addition, the phase center is in the same location for both the L1 and L2 signals
  • This, combined with minimal phase center variation between individual antennas, makes the GPS-702-GG ideal for baselines of any length
Durable, RoHS Compliant Design
  • In addition, the 702-GG meets the European Union’s directive for Restriction of Hazardous Substances (RoHS)
  • For extended life, the GPS-702-GG also features a waterproof housing and meets MIL-STD-202F for vibration and MIL-STD-810F for salt spray
