    one of the GPS recedivers im considering communicates according to the
    protocol specified in NMEA 0183, Version 3.01. This specification
    costs around $300, which at the moment i cant afford. im wondering
    whether there are any other methods of doing this. any help in this
    regard is appreciated.

    Just for GPS you don't need the spec. The GPS portion of NMEA is well
    understood and well documented by hobbyists. Besides, NMEA transmit
    data in ASCII text so it's easily human readable, debugged and reverse

    The following sites have been helpful to me:

    Especially this one because it documents a lot of the quirks of
    different GPS receivers which you definitely wouldn't get with the
    official NMEA spec:

    That is based on version 2 (or so) and my observations of the output
    of some receivers. I think the newer versions may add a few new
    sentences, and recommend that some older sentences not be used.

    NMEA-0183 (any version) is basically plain ASCII text sent at 4800
    baud. It should be fairly easy to figure out the content of the
    sentences by comparing the data to that displayed by the GPS (and/or
    applying some common sense...)

    My line of work is systems engineering, frequently on defence systems
    and often think that the cost of commercial standards must have
    greatly reduced their use. I'm sure the wholesale ditching of the old
    MIL-STD series has not been a good thing.
