Leica LGO 8.1 with Post Processing (GPS & GLONASS) Wanted

You should be able to submitt the raw files direct to OPUs without going through the RINEX step. You could also convert them with TEQC or WinTEQC. Our current Leica GPS receivers have the option to collect data in a RINEX format.

Thanks Steve.
Can you tell me more about the options you stated in your email?
I thought I still need to import RAW data into LGO (even basic) and then export RINEX file in order to submit the info to OPUS. I also know for a sure that it this point OPUS is not providing solutions utilizing GLONASS (it will be in 3-5 years according to them).
I never heard anything about other two option but will try to google it and get better idea about them.

Such Leica GPS are you using? The GS15 can save observations directly to RINEX we have to strip the Glonas and other stuff out with TEQC. Our old SR530 save data to a *.000 file. We can send that file straight to OPUS. OPUS uses TEQC to convert the files I am posting from my phone right now. Will post some link and other info from the office tomorrow. I have LGO but use OPUS Projects for serious processing.

I did check my GS14 does have RINEX files output option but it is not activated, so I need to pay Leica to be able to utilize it (got a message on the data collector screen). So I do need to figure out how to work with Leica RAW data files. I do have LGO Basic so I could certainly import the info into it.

Leica charges *extra* for RINEX conversion? That's a new one for me; every other hardware manufacturer makes RINEX conversion available without charge, usually via standalone application. Are you sure there isn't a no-cost Leica RINEX converter available for your PC?

I was talking about GS14 option directly output RINEX file as Steve stated in his message.
I didn't check with Leica how much they charge for this license but there is no doubt there is a charge. I do have LGO basic which does have an option for converting to RINEX after the info is imported.

I could be mistaken, but I believe OPUS will accept the raw .M00 file.

TEQC

TEQC is avaliable at http://www.unavco.org/software/data-processing/teqc/teqc.html

There is also a good tutorial there. TEQC is a command line driven program that you run from the command prompt. If you do the same process every time, you can developp a batch file to run TEQC and massage your data files to what you need for OPUS.

If you prefer to work in a windows environment, download WinTEQC at http://teqc.silkwerks.com/

This is a front end for TEQC developed by Mark Huber, a poster on this board. It is a very powerful option that will do some neat things. Mark is posting updates almost weekly.

Even if you convert to RINEX with LGO, you need these tools to massage the RINEX files.

My work flow for the SR530 is to load the data into LGO and convert to RINEX, them massage the files with TEQC and submitt to OPUS. We often collect data for 5 or more days on a secure point so I have some really big RINEX files. I use TEQC and a batch file I have developed to split the files into day files and submitt those to OPUS. With the GS15, I just strip out the extra signals and split them up.

We also have some X90 OPUS receivers. I use Win TEQC to massage the RINEX files to add antenna heights, point names and other meta data. Having all the serial numbers and antenna heights in the RINEX file is nice when you use OPUS Projects.

Gregory,

I think this can sum it up....

The GS14 that most dealers are selling comes standard with GPS/GLONASS and all other Leica options except Galileo tracking (which is not needed anytime soon, NMEA output, OWI (interface for third party software) and RINEX raw data.

The license key required to record static data in RINEX format is required for each receiver if the user wants it. The part number and list price is:

Art. No. 767811 LOP8. RINEX option, allows logging of RINEX data on Viva receiver. $ 500.00

What this does specifically is it always the static data to be recorded in a RINEX format so that the user does not need to do any conversions to send the data to OPUS or a another post processing software. There should be no need to edit the file at all. The only reason you would need to edit the file would be when you set up the GS14 to just stat collecting static data automatically when the receiver is turned on and never communicates with the controller to set the point ID antenna height etc. If you start the GS14 to log static data with the use of the controller the RINEX file will have all the information saved to the RINEX file. The only thing you would need to set is to use GPS only instead of GPS and GLONASS.

I am not sure what Steve is saying about having to massage the RINEX data from Leica. I need to email him and see what is happening or what he is having to do. I am just not sure what is happening with Steve's data.

If you want to see the method to do this in LGO then just email me and I have a guide prepared that describes what is happening with the receiver and how to do the needed export in LGO for RINEX go to OPUS. It is a very simple procedure.

I have been told also that OPUS will accept the native Leica .m00 files which are the Leica GNSS observations file for a job. I have not tried this method.

Jim,

Unfortunately Leica does not offer a free utility for converting their database file for static data to RINEX. I agree that that an utility should be provided for that process. I can start making that request again. For now they are offering the license key for collecting in RINEX format directly but that is priced in a receiver package or sold as a separate license key.

Steve,

I was reading through your replies again. I am not sure if you are collecting GPS and GLONASS for static data just to have the GLONASS data included for any future review or reprocessing with both constellations included in the data. It would not be a bad idea to have this in the file for reference if you need to go back and reprocess data at a later date with both sets of static observations. Maybe it is just a standard procedure.

I just want to make sure other users know that you can just observe GPS only static data by changing your settings. Say for example, if you are using the unit as a RTK rover using full GNSS capabilities. Then you need to observe some static data. You can then just set the receiver to observe GPS only. The static data will only contain GPS observations. The resulting file would not need to have GLONASS data removed manually or with software options. The setting can be done manually or setup in a separate Working Style for a quick way to set the receiver functionality for this type of work.

I appreciate everybody help with this matter.

Steve,
I am certainly going to download the software and try utilize it. I will let you know how it works for me.

Unfortunately Leica does charge for everything even I just paid for GS14 a lot of money.
The same story with TS applications- they activate them for 180 days and after that everyone has to pay for it in order to utilize it.
I just ones again would like to make it clear that I am trying to work my way out only for RTK survey because I am all set with Static.
Another thing the big advantage of the post processing software with GPS & GLONASS option is ability to utilize both cancellations which is not a case for OPUS and nobody knows for a sure when it will be.
Mark,
I was wondering if you could email me a guide prepared that describes what is happening with the receiver and how to do the needed export in LGO for RINEX go to OPUS. It is a very simple procedure.I do know how export RINEX file from LGO but still would like to see it.

I am not also sure how to submit to OPUS Leica .m00 files not utilizing any other software so hopefully the software I received from Steve will be solution unless someone knows how this type of the file could be submitted to OPUS, at least I couldn't find this option on OPUS website yet.

Gregory,

Post your email or just email me through the link by my name here in beerleg. I will send you the guide for review

Sure.
