MAIN FUNCTION
The system has combined inertial/satellite navigation mode and pure inertial mode.
Inertial guide built-in GNSS board, when GNSS is effective inertial guide can be combined with GNSS for navigation, and provide the combined position, altitude, speed, attitude, heading, acceleration, angular velocity and other navigation parameters to the user, while outputting GNSS position, altitude, speed and other information.
When GNSS is invalid, it can enter the pure inertial mode (i.e., it has never performed GPS fusion after power on, and if it loses lock again after fusion, it belongs to the combined navigation mode) After starting, it has accurate attitude measurement function, can output pitch and roll heading, and pure inertial can be static north finding.
The main functions include
l initial alignment function: inertial guide power on and wait for the satellite information is valid, the satellite is valid for 300s alignment, alignment is completed after the transfer to the combined navigation state inertial guide;
l combined navigation function: immediately after the initial alignment into the combined navigation state, inertial guidance using the internal GNSS board for combined navigation, can solve the carrier speed, position and attitude and other navigation information;
l communication function: the inertial guide can output inertial guidance measurement information to the outside according to the protocol;
l with the ability to upgrade software in situ on board: the navigation software can be upgraded through the serial port;
l with self-detection capabilities, when the system failure, able to send invalid, warning information to the relevant equipment;
l with wobble alignment function.
The inertial guidance workflow is shown in Figure 1 below.
