Hawkvine GNSS Receiver HV-GR004 Features:

●The integrated MDS series receiving radio modules include MDA (410-430MHz), MDB (430-450MHz), and MDC (450-470MHz) as alternatives, which allow the receiver to be compatible with many popular radio transmitters on the market.
●0.5W, independent of external radio while working within short range,eg. 1-2km (in good condition).
●The 4G internal memory capacity of GR004 allows mass storage of measured data for long time collection, which brings great convenience to your static work.
●Advanced data link with both UHF receiving radio and GPRS/GSM modules built in, switchable for radio/network RTK modes. 2 modules are separately installed to reduce interference, yet still a very small receiver.
