Raw GPS Data Acqusition from RINEX format
I am curious that if raw gnss data can be re acqured from a RINEX file?
Thanks for your help

to answer this question.
The Navigation file should have Ephemeris and UTC/ION parameters.
Almanac data is typically saved to YUMA files.
You'd do better processing the raw sub-frames from the receiver and decode data per ICD-200
Thank you for your attention,
Can I find raw sub-frames in a RINEX file or should I use an ublox receiver like LEA-M8 or LEA-6T?
Below there is a spreadsheet link that shows raw GNSS dataneeded for RRLP
I found some of them in the rinex files as per your post but a lot of them are missing
can you please suggest which way to go?
Can you please check it out?
The sub-frames are transmitted by the satellites, and contain the HOW/TLM along with the ephemeris, utc and almanac data.
The ephemeris/almanac both provide levels of orbital data, ephemeris being the most timely, and the almanac useful for long term positional estimates.
You should be able to get a u-Blox receiver to output the parameters in question, or generate YUMA and RINEX files with suitable software.
RINEX files are designed to allow post-processing which requires broadcast or precise ephemeris, and raw measurements of carrier phase, pseudo-range, doppler, etc.
