    A module for SurvCE version 6 software enables surveying with mixed brands of GNSS receivers and total stations. SurvCE is a data-collection software package from Carlson Software. SurvPC Hybrid + provides driver support for numerous devices, allowing the surveyor to interface with both types.

    Features of SurvPC Hybrid+ include:

    Follow Me. An alternative to optical tracking, Follow Me continuously turns the total station towards the prism using the location as determined using GNSS. This eliminates stray reflectors and lengthy searches.

    Smart Lock. The software will automatically detect when a user is slowing to take a measurement and lock on the prism so that it’s ready to go.

    Smart Staking. With smart staking, it will no longer be necessary to maintain optical tracking during stakeout. Stakeout directions are kept fresh using the GNSS receiver as the surveyor approaches a stakeout point. When close to the point, the total station will automatically turn and lock on the prism for the final staking precision needed.

    Cross Check. SurvCE will automatically cross-check the total station and positions determined using GNSS and warn the surveyor when they differ.

    Backup Tracking. With backup tracking, SurvCE will automatically show the position determined using GNSS on the map when the total station isn’t locked.

    Hybrid-Resection. Easy hybrid-resection allows for setup anywhere using positions determined using GNSS to calculate the total station occupied point and orientation. Measurements from the GPS and total station are time-synchronized for an accurate and simple one-tap resection measurement.

    Auto-Localize. Simplify setup by seamlessly auto-localizing the GPS receiver as total-station points are stored.

    Easy Setup Wizard. The easy setup wizard walks users through setup using auto-localization, hybrid resection or hybrid localization, then finishes with a cross-check for quick project start.

    Carlson Software has introduced a new four-constellation, three-frequency surveying receiver. The Carlson NR3 network rover weighs just under two pounds, but delivers highly reliable GNSS real-time kinematic (RTK) for land surveying, geospatial information systems (GIS) and other data-collection uses.

    Carlson Software President and Founder Bruce Carlson introduced the Carlson NR3 network rover at the company’s Grow With Us  User Conference 2019.

    Able to be used as a base or rover, the NR3 uses all four constellations — GPS, GLONASS, BeiDou and Galileo — and provides triple-frequency tracking on GPS, GlONASS and Galileo, the company said.

    Incorporating multipath and ionospheric detection, the NR3 maintains accuracy and continued operation despite shocks, vibration or other interference.

    According to the company, the NR3 is easy to mount and balance as it utilizes the optional Hybrid+ in Carlson SurvCE/PC that enables simultaneous interaction with GNSS and a robotic total station, the company said.

    ”The NR3 is Carlson’s answer for a lightweight – just 1.8 lbs. – network rover that can also be used in a base rover setup with Carlson’s Listen-Listen service,” said Butch Herter, Carlson’s director of Hardware Development. The Listen-Listen service allows base/rover operations via cellular modem for better correction transmission ranges compared to traditional terrestrial UHF radios.

    “It has hot swappable batteries and four come with the system that give it over a 20-hour runtime,” Herter added. “With the dual internal cell modem antennas, it maintains cell signal where others may not. When paired up with the Carlson CR2+ robot, it is the ideal companion receiver to use with the new SurvCE hybrid surveying system.”

    Produced by Septentrio with Carlson specifications, the Carlson NR3 has an integrated 4G LTE cellular modem, plus Wi-Fi and Bluetooth for modern wireless capabilities and is made to perform exceptionally in locations with bad visibility or interference.
