Positioning Application: What determines the value of the EOP parameters in the broadcast CNAV data?
EOP parameters in CNAV message Type 32 is taken from the content of the EOP_data.txt file
This file is located in the software directory "Datum files" folder, e.g. "C:\Program Files\Spirent Communications\Positioning Application\Datum Files"
Note for spacecraft vehicle users
The vehicle 'Reference file' contains a setting for "EOP data definition"
This only applies to the modelling of the spacecraft orbit
To ensure a match between the simulated orbit and the broadcast CNAV message, choose "User file"
