SunNav S26 GNSS Real time Kinematics (RTK) Receiver is a high-precision satellite navigation device used primarily in surveying, mapping, and geospatial data collection. The RTK technology enhances the accuracy of GNSS positioning data by using a fixed base station and one or more mobile receivers (rovers).
S26 GNSS receiver removes barriers to portability without sacrificing performance. Featuring full GNSS technology, S26 offers best-in-class GNSS signal tracking even in a harsh environment, enabling GNSS surveying beyond usual constraints and obstacles. The GNSS incorporates the latest innovations such as an inertial module providing automatic poletilt compensation in a very compact design.
The market price for S26 GNSS Machine including all the accessories is USD. 8,000.

Features of S26 GNSS RTK Receivers
GNSS+IMU RTK Technology: Built-in inertial navigation module, you can measure it when you click it. As long as the pole point is aligned, the precise coordinates can be measured even if the pole body is tilted. The measuring point efficiency is increased by 20%, and the staking efficiency is increased by 30%.
Built-In UHF Radio: S26 GNSS has built-in low-power transceiver integrated radio module, which can realize automatic switching between mobile station and base station.
Full Constellation Multi-Band: S26 fully support BDS, GPS, GLONASS, Galileo systems, adapt to a variety of complex and harsh environments, and ensure centimeter-level positioning accuracy.
All-In-One Design: It comes with built-in Blue-tooth, radio, storage, positioning,inertial navigation, antenna and other modules tomeet various needs of measurement work.
Built-In UHF Radio: Has built-in low-power transceiver integrated radio module, which can realize automatic switching between mobile station and base station.
Can Be Extended to Dual Antennas: Built-in integrated positioning and heading board, can be connected with an external antenna, to achieve high-precision heading applications.
Full Constellation Multi-Band: It fully support BDS, GPS, GLONASS, Galileo systems,adapt to a variety of complex and harsh environments, and ensure centimeter-level positioning accuracy.
Large Capacity and Long Battery Life: It has built-in battery with a capacity of up to 10000mAh, which can achieve more than 14 hours of continuous battery life, ensuring long-term operation in harsh outdoor environments.
Strong Compatibility: It adapt to transparent, TRIMTALK, South and so on multiple communication protocols in the market.
NFC Connection: It is equipped with an NFC chip, users can easily connect the S12receiver and the data collector with just one touch, without searching for pairing.
Two Operating Modes Interchange: The base station mode and rover mode can be switched freely according to needs.
