Product Description
As a new generation of highly integrated handheld GNSS RTK device with a stable and accurate data processing module, eFix R2 Series, easy to carry with stable performance, can perform high-accuracy RTK survey by connecting an external GNSS antenna, while centimeter-level positioning accuracy could be easily reached by the built-in GNSS antenna.

Product Feature
1.Uniform-designed Base and Rover
The standardized base and rover design makes it interchangeable between base and rover in all kinds of operation mode, greatly increasing productivity with easy setup.
2.Most Advanced GNSS and RTK Technology
Integrated both surveying and navigation GNSS receivers in one, it supports dual frequency GNSS, which enables fast initialization and satellite tracking, lower-elevation-angle satellite tracking, globally advanced multipath mitigation technology, achieving high-accuracy real-time survey with jamming resistance and fast, reliable, long-range data transmission. 
3.Flexible Data Transmission Mode
3.1) Built-in 2G/3G communication modem, integrated with Bluetooth and WiFi. Users can easily carry out high-accuracy RTK survey by connecting to local CORS or by self-built base station with GEOSUN Server data retransmission service. 
3.2) Users can also choose external radio with low power consumption, which is with adjustable output radio-frequency and *6 customizable channels.
4.Intelligent Fault Self-diagnosis
With the built-in intelligent self-diagnostic system, eFix R2 Series could automatically report the abnormals by voice alarm.
