Embodiment Construction
[0062] A method for using inertial information to assist satellite receiver tracking loop processing according to the present invention will be described in detail below in combination with specific embodiments.
[0063] The present invention uses inertial information to assist satellite receiver tracking loop processing method, comprising the following steps:
[0064] Step 1. In the case of no inertial information assistance, adopt the traditional tracking loop; in the case of inertial information assistance, use the tracking loop in the form of inertial assistance; the switching of the two loops is determined by whether there is inertial information;
[0065] Step 2. The carrier acceleration information output by the inertial navigation is used as the inertial auxiliary information, and the acceleration information is converted into the line-of-sight acceleration information of each tracking satellite;
[0066] Step 3. The line-of-sight acceleration information of each star ...
