GNSS Receiver with Inbuilt Antenna+RTK+Inertial System

Overview

VLG’s G-mouse has dual-frequency multi-mode high-precision positioning antenna, RTK dual-frequency multi-mode sub-meter high-precision positioning module and six-axis gyroscope high-precision inertial navigation module. It can quickly realize star receiving, positioning and inertial navigation, and is very convenient to use.

Key Features

• Indoor Operation

The GM can automatically switch between satellite navigation and inertial navigation, and maintain sub-meter high precision positioning even when driving into “tunnels and underground parking lots”; In “urban canyons” and shaded environments, it filters drift signals and gives precise locations.

• 4 Satellite system

Supports Beidou, GPS, GLONASS, Galileo, and QZSS satellite signals in L1+L5 bands. It is capable of capturing and tracking any multi-satellite hybrid signal, independent of the RTK ground enhanced base station system. In complex urban environment, it can still achieve stable and higher sub-meter positioning accuracy.

• Excellent Inertial navigation Sys.

GM inertial navigation algorithm can output the three-dimensional attitude of the vehicle, such as: turn left and right, uphill and downhill, left and right turbulence, collision and overturn; It can record and judge dangerous driving behaviors of drivers in the way of data, such as: rapid acceleration, rapid deceleration, sharp-turns, dangerous lane changes, fast driving on bumpy roads, collision and rollover, etc.
