    Hi all I have been searching for the gringo software for days now with no luck, poor mans survey as I'm trying to use a handheld Garmin to create ground control points for airial drone mapping projects which I can then post process to be engine the position using PPP.

    If there is anyone out there with a copy of this software even just the trial version so I can test the concept it would be massively appreciated!!

    I've attempted to use the gar2rnx java script but can't get it to work.

    If there is anyone who has a copy of gringo or some information on how I can get the raw GPS data from my garmin vista into rinex format it would be massively appreciated!

    King regards

    Maybe you could contact the of University of Nottingham, possibly Terry Moore?, it looks like Gringo only works with older Garmins i.e. GPS12 and Etrex, (not gpsmap6*) for example, I guess this is because newer units don''t output the relavnt NMEA sentences

    EDIT
    It looks like Gringo will work with newer Garmins, (released since the program was written), you have to add a line to the ini file, e.g. :-
    GPS60 works with ForceFormat=2 (0 - 4 is valid)

    Hi newbi,

    I have emailed professor Moore but I'm yet to receive a reply. Fingers crossed he comes back. Just a real shame that a software as fantastic as this now seems unobtainable. I'm banging my head against a wall trying to get this java gar2rnx executable to work.

    I'm assuming you don't have a copy of the program?

    I have an old etrex vista so I think the required data can be exported over Rs232 and jacked through an A10 driver into my laptop.

    No I don't have a copy of the software, only the user manual, I did see a post that said the owners of Gringo sold the program to a firm that now call it Rhino and I guess they were forced to remove links to the old program, you may still get a copy from the university Though

    Hi there, The guy at Nottingham who used to do the GRINGO software, was a guy called (Dr) Chris Hill, not sure if he's still around, it's years since we had any contact. He wrote the software and the manuals for it. He published a few academic papers about possible uses for the software, some of which were available online. The 'trial' version of the software wasn't much use, it only recorded a few seconds of data, then switched off. Basically just to prove that it worked on your particular receiver/computer combo. The 'full' version was a commercial product, that cost £100 for a licence if I recall. The software was fitted with a pretty comprehensive anti piracy routine, that was purchased from a specialist company. It's maybe 10 years since I last used the software, I remember seeing online that the university were no longer selling the software, presumably there weren't that many takers, given the cost. Also, even consumer grade SBAS enhanced receivers are capable of significantly better accuracy, probably enough for most uses, unless you specifically need survey grade accuracy. The results I got with GRINGO were pretty impressive, considering the age/type of GPS receivers I was using. typically within 50cm when used over an OS passive station, with a couple of hours occupation time. The software was licensed to a company called US Positioning, of Mesa, Arizona, if I recall. Their software was sold for in excess of $1000, they licensed the algorhythms from Nottingham, but the 2 products were on the market at the same time. US Positioning are long gone, presumably went out of business. The main drawback of using the GRINGO software was that you had to have a laptop hooked up to your receiver logging data the whole time you were on site, there was a piece of post processing software called P4, that came with GRINGO, but only worked if you had a licensed copy. I was running mine on Windows 98, not even sure whether GRINGO would run on newer Windows, seem to recall some issues that people had with it trying to use RS232/USB converters, as opposed to serial ports on the actual PC. I'm pretty sure that I have copies of both GRINGO and Rhino Rover, which was the USP licensed version, there is a code with the Rhino, that gives you 14 days of use, if I recall. The GRINGO is just a trial version, of course. In terms of post processing, there's a post processing program that came with USP, which I'm pretty sure I have on a CD somewhere, but it might take a while for me to sort it out. Hope this helps.
