Changing the date in the BRDC file about bladegps HOT 14 CLOSED

RINEX file editing is not something supported by the bladeGPS. If you want to do it by yourself, you have to change the corresponding TOE (time of ephemeris) and the GPS week number in addition to the TOC (time of clock). The location of the TOE is the first column of the fourth row, and the GPS week number is found in the third column of the sixth row.

@nzkarit did you try editing like @osqzss suggested? Curious if you had success.

Just found this, I haven't tried it yet. Looks promising. https://github.com/SGL-UT/GPSTk/blob/133e24f5747120f57f44624d7a220814b495f27a/ext/apps/Rinextools/README

Try the latest gps-sdr-sim with '-T' option to overwrite the TOC and TOE to the user-specified scenario start time. If it works okay, I will merge it to bladeGPS.

@osqzss the -T option in gps-sdr-sim performed as expected. I would merge it to this project.

I'm also working on the leap-seconds support now. The both will be merged to bladeGPS in this week.

Would it be easy to have an option that would use current date and time? Like -T NOW or a separate option like -TC

from bladegps.

"-T now" seems nice. I will add this option, too.

Thank you! That's going to be very helpful.

@osqzss If the date and time I choose is in local date and time, is there any conversion of the date/time to UTC or is it used as-is? If there is a conversion, then I would want to do an additional test.

from bladegps.

Try mktime and gmtime.

"-T now" option is available in gps-sdr-sim.

Excellent, thank you.

Thanks working for me on gps-sdr-sim. Haven't tried on the bladeGPS as still trying to figure out libraries on linux.
