But you need the raw data messages, if you want to use the Freerunner as a base station for DGPS (and running around with another Freerunner using that base station). As far as I can remember there are also tools to measure the distance between two measurement points by using these raw messages.

Re: [Fwd: u-blox binary protocol boilerplate code]
According to the datasheet for the chip ATR0635, DGPS is a supported feature: http://www.u-blox.com/products/Data_Sheets/ATR0630_35_SglChip_Data_Sheet(GPS.G4-X-06009).pdf If I'm reading this correct, we've also got "supersense" available, which should improve accuracy. I'll be the first to admit, however, that I really am not the best person to talk to about the technical side of such things.

Re: [Fwd: u-blox binary protocol boilerplate code]
We're looking to develop a combined DGPS and A-GPS application for the platform, for which we need the data contained within this binary protocol. We're already using an application that gets GPS data from GPSD (TangoGPS), one that gets its data from the FreeRunner's internal serial port (an in house produced geo-tagging application); but now we're thinking of higher accuracy applications. All will be released at openarchaeology.net when it's ready.

There are some commands that only operate in the proprietary binary format... the main NMEA sentences though contain everything you would normally expect from GPS and spew once per second automatically. The binary and NMEA stuff coexists on the same UART. Some stuff like stashing and restoring the data it took time to get from the satellites is done in the proprietary binary mode, handy to recover GPS quickly from suspend for example. - -Andy -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkg9HioACgkQOjLpvpq7dMoCGwCcDklgvlijQsudLyJ77a1kzjyx 8XYAnj839qFIAaBjwvVa0dWs/N4x31K7 =vwb/ -END PGP SIGNATURE- ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Since this question might be of general interest, I've taken the liberty of answering it on the list. Joseph asked about u-blox code, and Andy pointed us to the DM2 test code: http://git.openmoko.org/?p=gta02-production-testing.git;a=blob;f=gta02-dm2/src/dm2.c;h=caddb49b2a7abca366e83dd36b87aa9ce857d416;hb=HEAD#l517 - -Andy Original Message Subject: u-blox binary protocol boilerplate code Date: Tue, 27 May 2008 11:52:14 +0100 (BST) From: Joseph Reeves <[EMAIL PROTECTED]> To: michael <[EMAIL PROTECTED]> Hi Michael I'd like to request if there's any boilerplate code available to deal with the binary protocol as provided by the FreeRunner's u-blox chip? This would be a great help to us. Many thanks, Joseph -- Files attached to this email may be in ISO 26300 format (OASIS Open Document Format).
