Hi -- I've written a Python program to download R-files from an Ashtech Z12 receiver. I'm successfully getting files, but the recent GPS WNRO event has messed things up. I'll be releasing this program with GPL once I have it working (it'll be on my github -- https://github.com/n8ur).
I've tried feeding my result into teqc with the -weeks option but although I can get it to report the correct date, the +qc option reports an ephemeris error that seems to indicate something else needs to be corrected, with a 1999 year showing up). If I knew the layout of the R- file (record structure), I think I could patch the TOW values in the binary, hopefully fooling teqc into making a valid RINEX file. I know that the Ashtech file format was considered proprietary 20 years ago, but in the meantime has anyone figured it out? Any info would be greatly appreciated. If I can't make the R- file download work, we can stream the data to PC in real time, but the ability to collect without a PC connected would be very useful. Thanks, John PS -- why work on such an ancient receiver? Well, we got several of them for a good price and want to use them for time stability measurements of precision frequency standards. _______________________________________________ This message is sent to you from FOSS-GPS@lists.osgeo.org mailing list.
