Hawkvine GNSS Receiver HV-GR019 Features:
●Adopting advanced Pacific Crest Maxwell 6 custom survey GNSS technology, GR019 GNSS Continuously Operating Reference Station(CORS) system with 220 channels for multi-constellation tracking provides high accuracy, productivity and efficiency. It is capable of tracking signals from GPS, GLONASS, Galileo, Compass(BeiDou) constellations.
●Embedded with Linux operation system to support multi-user, multi-task and multi-platform operation with complete system connectivity. Five RS232 ports, Ethernet port, GSM antenna port, high accurate atomic clock port, and four power inputs combined with an industry leading 20Hz data rate, GR019 provides high speed connections both in and out of the reference station.
●provides data for postprocessing and it provides an accurate reference station service that can be used in the filed by multiple one-person crews. The reference station network can be built up with several reference stations to increase the area of coverage. With the capability of collecting and saving RINEX and BINEX data, GR019 is fully compatible with the existing CORS networks in the world market, perfect for establishing new CORS systems or expanding current CORS networks.
●Has exceptionally low power consumption, simultaneously supports multiple-way AC/DC power supply such as solar or wind-solar hybrid power supply. Also, GR019 has backup power supply to ensure no data is missed. GR019 has internal compact flash card with up to 1GB of data storage and available for maximum 32GB data storage extension by SD card. It supports long-time massive data storage, and the data is well backed up during output.
