Hawkvine GNSS Receiver HV-GR007 Features:

●A smart speaker is particularly designed for this machine to offer guidance for users during operation. The operation of the product is very simple. There is no need for you to set up parameters for each operation. For example, you can press the button to have the setting-up done automatically. With this product, field work can be finished conveniently.
●GR007 is provided with 220 channels. It is fully compatible with GNSS satellite constellations to track GLONASS, GALILEO, BDS, SBAS, GPS, etc.
●In the same receiver, the working mode is switchable between the base and the rover because of the UHF radio transceiver. There are 2 watts Hawkvine internal UHF radio and 1 watt Pacific Crest TrimTalk© internal UHF radios for your selection, which are used for UHF RTK operation and to enable the product to work in conjunction with the receivers of other brand with Trim Talk© compatible radios, respectively.
●Internally designed with GPRS or 3G modem, GR007 GNSS RTK system can operate with the correction from CORS networks in CMR or RTCM. Importantly, messages are needless to be interpreted and can be read seamlessly.
●This product is powered by 4400mAh Li-Ion battery with the static working time of 13-15hours. Meanwhile, the battery working time of RTK rover (UHF/GPRS/3G) is 10-12 hours and 8-10 hours for RTK base.
●The enclosure protection conforms to IP67 standard. The flexible flat cables are well protected with good resistance to 3m natural drop onto concrete. Even under impact or vibration, customers can use the product freely.
●The controllers and software for the GR007 GNSS RTK system are optional. Besides the standard field & software manufactured by Hawkvine, the controller with OS Microsoft Windows Mobile 6.5 is also compatible with the software of the third party like Carlson SurvCE, MicroSurvey FieldGenius, Digiterra Explorer, ERI ArcPad, etc. Configured with Wi-Fi, Bluetooth, and GPRS/3G, the Hawkvine controller can be connected with other device, server or can collect data without any wire simultaneously and seamlessly.
●Geomatics Office (HGO) software can provide GNSS solution with a complete suite of programs to support GNSS receivers. Therefore, the standard RINEX data and the raw data can be easily and flexibly processed.
