Carlson Software Carlson NR3 GNSS Receiver

Accurate. Light weight. Versatile.

The Carlson NR3 is a compact GNSS Smart Antenna designed for Network Rover applications. The light weight NR3 combines with a Prism on a survey pole to make a very portable yet complete assembly to operate with GNSS and a Robotic Total Station simultaneously using SurvCE/PC 6.0 with Hybrid+.

In addition to being small and low weight, the Carlson NR3 leverages powerful satellite navigation technology for reliable RTK GNSS.

Description

The Carlson NR3 is a compact GNSS Smart Antenna designed for Network Rover applications. The NR3 and a prism make a light weight survey pole assembly to utilize SurvCE/PC 6.0 with Hybrid+ for simultaneous GNSS and Robotic Total Station surveys.

 

KEY FEATURES
• GPS, GLONASS, BeiDou, Galileo
• Light weight 820 g (1.8 lbs)
• Hot-Swap Batteries
• 4G LTE Cellular Modem
• Wi-Fi 802.11 b/g/n
• Bluetooth 2.1 + EDR
• 16 GB Internal Memory

 

GNSS Technology
The NR3 utilizes 4 constellations to produce reliable GNSS RTK, with triple-frequency tracking on GPS, GLONASS and Galileo. The solution incorporates multipath and ionospheric detection algorithms to maintain accuracy while exhibiting stable satellite tracking during shocks or vibration. The light weight NR3 receiver may be used as a Base or Rover.

 

A Perfect Pairing with Carlson SurvCE or SurvPC, Data Collection Software
The new Hybrid+ feature allows simultaneous interaction with GNSS and a Robotic Total Station, with the GNSS and prism both mounted on the survey pole. Hybrid+ provides increased Quality Control as there are two instruments measuring the same point. In addition, GNSS position at the pole allows a faster prism acquisition than traditional searching, as well as improved tracking. Hybrid+ allows easy setup anywhere using GNSS coordinates, and minimizes common survey challenges from stray reflectors, false fixes and obstructions.
