I just have one quick question.
I generate simulator for known coordinate station (CORS station by NGS ) since we have observation file for the same date and time from NGS. I noticed the Range based on Pseudorange generated by simulator is too different compared with Range from NGS website for the same date , time and satellite. I attached couple of screenshot to be more clear. Do you have any idea why it is too far. Is doing simulation in NONE mode effect ?
I also compared Navigation file between two , Some Keplerian elements are too off
The CORS station is p375. Date:2022 1 1
If you could please take a look and give me your suggestion , I will really appreciate Compariosn_None.pdf (509.0 KB)
Yes, the pseudorange calculation on the observation file is the distance from the receiver antenna to the satellite antenna, including receiver and satellite clock offsets, and other biases such as atmospheric delays.
