The indirect coarse alignment method has better angular shake anti-interference ability, but the line shake anti-interference ability is relatively weak in a short period of time. If the coarse alignment time is extended appropriately (generally in the order of minutes), the indirect coarse alignment method is often inferior. Can achieve good results. The indirect coarse alignment method is a very practical SINR coarse alignment method, which has been widely used
Before the inertial navigation system enters work, initial alignment is required to make the inertial navigation system point in the same direction as the local navigation coordinate system, so that the inertial navigation system can better enter the working state. The blogger uses C language to realize indirect coarse alignment, which has more advantages than analytical coarse alignment.
