Embodiment Construction
[0021] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0022] The TSE real-time calculation method in a kind of RNP of the present invention, method flow chart is as follows image 3 As shown, it specifically includes the following steps:
[0023] Step 1: Calculate the navigation error probability ellipse through the navigation equation.
[0024] Establish the satellite navigation nonlinear observation equation:
[0025] ρ π = | | p π ENU - p r ENU | | + C b - - - ( 1 )
[0026] where: ρ π is the pseudorange of the πth visible satellite, is the position of the satellite in the ENU coor...
