Okay, I understand. Yes, you can configure which GNSS satellites to exclude using the graphic user interface called J-Field. So for example, if you were using the Triumph-1M as an external antenna and connetced to a device running J-Field, you could uncheck the box for GPS... though I am quite puzzled why you would want to do that.
I have not been able to get a fixed solution with the Triumph-LS without GPS. As Kelly notes, the settings are available in the J-Field software we are using, but I have not had success with it. I do recall that I left the timing set to GPS time, so perhaps this was a conflict. I'll try testing a bit more. I realize you are asking about the Triumph-1M but the receiver board is the same so I would expect that if I can do this with the LS then the 1M should also be able to as well.
As a note, I have been able to get fixed solutions with as few as three gps satellites in the solution.
Javad Mobile Tools (JMT) for Android currently has support for the Triumph-1, Triumph-2 and GISMore; and does not currently list the Triumph-1M. JMT is not intended as a replacement for J-Field, nor is its development necessarily headed in that direction; however, when the Triumph-1M is on the JMT pick list (as I expect to see at some point), you should be able to control it in much the same way as the other Javad GNSS receivers built with internal GNSS antennas.
Thank, Shawn. I hope that the developers will solve this problem.
Kelly, can control the receiver with something else other than Victor-LC and program J-Field? Controller Victor with Trice program can do this?
Another question on the Triumph-1M. Can I use the receiver as a base station? Can i adjust the recording data every 15 seconds?
Thank you, Shawn and, please, confirm this information or refute this.
I hope to use, sometimes, TRIUMPH-1M with external antenna as a base station. If, of course, developers will confirm that Victor with Tracy (or another soft) can manage TRIUMPH-1M.
The Victor-LS bit expensive than Victor
Maksim, I would still recommend the Victor-LS. It will run J-Field which contains many new features and improvements that we have all been working hard to implement. I don't think it would take you long to recuperate the cost difference using all the improvements in J-Field.
I can confirm that Tracy does support the Triumph-1M. Unless you have a special application, I don't think you will need an external antenna with the Triumph-1M. I'm still looking into whether the Triumph 1M can get a fixed solution without GPS satellites.
Matt, thanks for the offer. Shawn, thanks to you once again. External antenna may need if the receiver to install mode base station for a few months, for example. In this case, the receiver must be protected from external influences (including human impact), provide an external power supply and it be connected to the computer.
Sorin is much better equipped to answer your specific questions regarding this, Zoltan, however I wanted to share a couple of screen captures from yesterday.
This is from the screen of the Triumph-LS:
Each box represents an RTK engine. In the upper left corner of each box (showing 0) is the number of GPS satellites used by that engine. In the upper right corner of each box (showing 7) is the number of GLONASS satellites used by that engine.
