Embodiment Construction
[0087] Since the small and medium scale parallel signal transmission branch, large scale parallel signal transmission branch and ultra large scale parallel signal transmission branch realize the same principle in real-time satellite navigation signal transmission technology, for this reason, this example will use the navigation satellite transmitter as the medium and small The realization of the large-scale parallel signal transmission branch system is explained, according to figure 1 The implementation steps are as follows:
[0088] S1 takes satellite parallel signal transmission branches as 4 channels;
[0089] S2 generates a binary satellite navigation message with a length of 24 bytes, divides it into 4 groups, each group has 6 bytes, and forms a 4×6 matrix;
[0090] S3 sends the grouped satellite navigation messages to 1~4 parallel signal transmission branches in turn;
[0091] S4 takes the state variable x of 3 x with different parameters 1 、x 2 、x 3 A set of non-li...
