    Any fool can obtain 10,000 occurences of the alphanumeric sequence
    "RINEX2" on google. For example, see the first response I got.

    Sam, your reference above tells me nothing about how RINEX2 data might
    possible be of some use to me - or indeed to anyone except those
    working with data from some European study done a decade and a half
    ago. I had already read several documents on that Swiss exercise
    prior to posting my question.

    I would like to find out if "RINEX" data might possibly fit into a
    solution for a problem I am tinkering with.

    >From time to time I would like to perform topographic surveys with a
    precision of approx. +/- 10 cms vertical precision far enough away
    from my RTK base station that radio contact is questionable/difficult
    and OTF RTK operation is unlikely to work. By topographic surveys I
    mean I want to collect enough data to make a somewhat accurate contour
    drawing of a potential construction site for cost estimation purposes.

    I do not want to sit on any point for any length of time, and I do not
    need to know the location of anything to any great precision, like
    mm's or anything, so I cannot see OPUS or any of the survey data
    reduction software that I have looked at so far being of any use to
    me.

    I suspect I might be able to do what I want by collecting data with a
    rover receiver that I can later correct to an adequate level of
    precision using data from my own or someone else's base station data.

    But so far, after looking at OPUS, FKYKIN, TGO and a significant
    number of other possibilities, I am hardly any further ahead than when
    I started.

    So let me rephrase my question.

    Does anyone here know how to do the job I have described above because
    they have actually done it and can tell me how to set up my rover to
    collect the data I need, how to set up my base to collect the data I
    need, what software I can get to apply the corrections to my collected
    field data, and what steps I can go through if there are alternative
    methods to achieve the same results I have described above?
