[gpsd-users] gpsrinex: collecting one 24h GPS-day?

[Anders Wallin]

Hi all,

I'm getting started with PPP experiments using an u-box F9T.

Is there a mechanism for collecting one 24h calendar day (GPS-timescale) into a RINEX file?

gpsrinex -i 30 -n 2880

will do roughly what I want, but do I have to rely on cron to trigger this at the right time (system time is UTC, so the UTC-day is 18s offset from the GPS day I want in the RINEX file...)

another way to achieve this would be to collect an over-long RINEX-file with gpsrinex, starting 10min before GPS midninght and ending 10 min after.

and then use another tool like teqc to cut-to-length the overlength RINEX.

any other ideas?

thanks,

Anders
