Hawkvine GNSS Receivers HV-GR001 Features:

●GR001 with smalller size and innovative design, the weight is only 970g, is built with magnesium alloy materials. And the top edge is designed to decrease harm for receiver in case of fall down to ground.
●Equipped with bluetooth 4.0 module, which supports receiver to work well with smartphone and tablet etc, also making bluetooth communication faster and more stable.
●The internal tilt sensor helps receiver to survey without centering, in order to improve survey efficiency, and tilt angle can reach 30 degree maximum.
●The internal electronic bubble sensor can correct the survey result, to support receiver to survey without level.
●Travel light, makes the surveying no longer bear heavy load. New miniature RTK surveying system, the receivers and bags have become more compact, and the weight of a full set of equipment reduces by 30% compare to the previous generation.
●System can track most signal from all kinds of running satellite constellation, especially support B1,B2 and B3 signal from BeiDou, also is able to get position result with only BeiDou signal.
●A based on smart platform and powerful structure, which can make system work faster and more stable, less power consumption, and can also monitor the status of each parts real time, extend battery life in the field.
●7*24 hour cloud service, which enable make service and support more quickly, such as online upgrade and register, remote diagnosis etc.
●Integrated with new and excellent datalink system, compatible with current radio protocols in the market, also supports all kinds of network types to access CORS seamlessly.
●The internal NFC module can make the complicated bluetooth communication more simple and easie

GNSS Receivers HV-GR001 Standard Packing:

External radio transmitter (standard supply)
Our high speed wireless digital radio is integrated with ten years radio design and production experience of Hawkvine,adopting radio frequency and digital processing,baseband processing technology, air transmission rate reaches to 19200bp, radio-frequency emission power top to 25W, reliable performance, strong stability ,is more suitable for RTK fieldwork.

RTK carrying case
The convenient RTK carrying case is customized for surveying workers, which adopts double oxford tabby textile fabric and YKK industrial grade waterproof zipper. It has strong abrasive resistance and waterproofness. Meanwhile the unique backpack design reduces the heavy burden of field work.

Surveying software
GR001 RTK surveying system can equipped with Hawkvine professional surveying software for special industries, such as engineering star, SurvCE, FieldGenius and so on.
Engineering star (standard supply): it’s our kernel surveying software, the main functions are detail survey, stake out point, stake out line, coordinate system transformation and so on. It’s a powerful and efficient software for RTK survey.
