Hawkvine GNSS Receiver HV-GR002 Features:

●Embedded Linux operation system+ intelligent cloud platform.The receiver is no longer an independent hardware device, it’s a complete intelligent operation system with web page cloud platform.
●E-bubble The internal Electronic bubble sensor can correct the survey result and support receiver to survey without leveling.
●Tilt survey The internal Tilt sensor helps receiver to survey without centering, in order to improve survey efficiency, and tilt angle can reach 30 degree maximum.
●Internal radio Internal transmission and receiving radio module supporting Trimtalk450S and protocol change and high, medium and low power switch.
Network Adopting new network program frame, it supports all kinds of network types to access CORS seamlessly. 3.5G high speed network and is extendable to 4G.
●Using the intelligent PPP dialing technology and adopting the network loading mechanism same to the smart cellphone. Keeping GR001 online continuously during the survey, making connection much faster
●Adopting the WIFI as the data link which improves the measurement result, and the AP hot spot function make any smart terminals can connect to the receiver to control it
●GROO2 is able to transmit the correction from reference station to other Rovers by its excellent internal radio, greatly improve the utility of device and the flexibility of fieldwork
●iVoice intelligent voice technology provides status and operation voice promptly, and supports multiple languages.
●Equipped with most advanced GNSS boards,GROO2 system can track most signals from all kinds of running satellite constellation,especially support B1,B2 signal from Beidou, also is able to get position result only with Beidou signal.
●The internal Web UI management platform of ROO2 upports WIFI and USB mode connection. Users can monitor the receiver status and configure it via the internal Web UI management platform.
●0.96 inch HD OLED colorful LCD supporting multiple language display and it is suitable to field work with high brightness and low power consumption.
●Built-in several thermometer sensors,intelligent temperature control technology, monitor and adjust the receiver temperature real time and guarantee the best work status.
