TR7 GNSS Receiver
High Precision TR7 GNSS Receiver GPS GNSS RTK for Construction land Survey Equipment
TR7 can transmit the correction from reference station to other rovers by internal radio. Made fieldwork more flexible. Multiple rover stations can share differential signals with one CORS account, that cost savings.800 channels multi-constellation and multi-protocol radio receiver, compatible with various brands.
Description
TR7 is the new high-quality GNSS receiver of SatLab. 800 channels multi-constellation and multi-protocol radio receiver, compatible with various brands. It has full band support for 4G/3G/2G cellular mobile networks and also supports WiFi/BT4.0/NFC/OTG.
Tilt survey will be done by just shaking the RTK pole. A High-resolution OLED panel can assist surveyors to check the working states of the receiver. TR7 GNSS system provides surveyors with industry-leading GNSS solutions.
