Main functions of the system

It has the function of outputting information such as carrier position, heading, attitude angle, angular rate and speed in real time;
It has working modes such as pure inertial navigation and INS/GNSS (including Beidou) integrated navigation;
Possess the function of receiving satellite navigation information provided by external time system frequency standard equipment;
It has the function of ground self-alignment and supports the function of air alignment;
It has functions such as power-on self-test, periodic self-test, status report, installation error compensation, and non-volatile storage.

System composition and dimensions

The whole system is composed of two parts: the inertial navigation main instrument and the inertial navigation main instrument bracket. Among them, the external dimensions of the main instrument are as follows:
