What is INS?

Inertial navigation system (INS) is an autonomous navigation system that does not depend on external information and does not radiate energy to the outside. Its working environment includes not only air, ground, but also underwater. The basic working principle of inertial navigation is based on Newtonian mechanical laws. By measuring the acceleration of the carrier in the inertial reference system, integrating it with time, and transforming it into the navigation coordinate system, the information of speed, yaw Angle and position in the navigation coordinate system can be obtained.

Why chooseing VLG's G-mouse

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.

It also 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.

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.

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.
