G7 Installation & Operation
Getting Started with G7
About the Receiver
The G7 GNSS receiver incorporates a GNSS engine, GNSS antenna, internal
radio (403 MHz – 473 MHz), 3G cellular modem, Bluetooth, WiFi module, with
various interfaces such as Ethernet in a ruggedized and miniature unit that is
easy for you to set up for an all-in-one RTK Rover or mobile Base Station.
Bluetooth and WiFi technology provide cable-free communication between the
receiver and controller.
The receiver can also be used as the part of a RTK GNSS system coupled with
COMNAV Data Collection software to download GNSS data recorded in the
internal memory of a receiver for forwarding to a computer. To configure the
receiver for performing a wide variety of functions, you can use the web interface
by connecting the receiver with PC or smartphone via WiFi.
RTK Operation
The G7 automatically tracks satellites in view when powered up with antennas
connected to the ports on the receiver. Position and heading accuracy will
depend on configuration settings, location, and environment.
Position
performance will improve with RTK and differential GNSS. Distance between
the dual antennas (baseline distance) will have an impact on heading accuracy.
The differential GNSS and RTK will eliminate the effects of atmospheric errors,
timing errors, and satellite orbit errors while improving system integrity.
SBAS Tracking
The G7 automatically scans and tracks SBAS signals without the need to tune
the receiver. Smart algorithms provide the unit with consistent tracking of SBAS
satellite signals in areas where signal blockage of a satellite is possible. SBAS
selection can be configured and optimized via the software menu display.
Multi-frequency Multi-constellation GNSS
The G7 is designed in its standard form for multi-frequency GNSS to
simultaneously track all in view satellites thereby providing the highest accuracy
and stable (optimized for best possible uninterrupted signals) precision position
and heading at all times. The system optimizes reception of GPS, GLONASS,
Galileo, BeiDou, at all times based on selections configured in the software
menu to provide stable precision heading, position, rate of turn, pitch, roll and
heave at all times.
