GPS simulation from that day

[Flavien.Rx]

Hi everyone!

Situation : I have a GPS Toolkit for GPS simulation and with Almanacs and Ephemerides files, RF boards and PXI I send a GPS localisation for my A-GPS receiver.

Problématique :  For the localisation, it's ok but for the date my receiver update with the date of the Ephemerides files. I don't want that because Ephemerides files are generate with 1 day later and i want the date of to day ! 

Question : Is it possible to create, generate Ephemerides files with the date i want or edit the date in ??

Thx a lot to read my post and sorry for possible grammatical error.

Please share some of your code, so we can see what you're dealing with that what your data looks like. I would assume you could add a numeric value to your timestamps to shift them by 1 day to match what you want.

Check the time zones.  GPS usually works off UTC.
