Multi-Constellation with Standard LS - Tips for getting started

I've sent this (or versions of it) to a few customers now. I'm bringing it here for your reference.

On the Triumph-LS:

Make sure that you have the latest versions of software installed.

Make sure that GPS, Glonass, Galileo and Beidou are turned on. Go to Setup and Edit the General Group Profile (top of the screen). Select Advanced > GNSS > Systems & Signals Tracking. Constellations that are on will be white, off will be gray.



On the Triumph-3 / Triumph 1-M:

Make sure that the OAF is up-to-date on the Triumph-3 / Triumph-1M. You can use Base/Rover Setup to update the OAF. With the LS connected to the Internet, connect to the Triumph-3 /Triumph-1M by Bluetooth, then select the button below Start/Stop Base (it has the name of the base and rover). You’ll see an option for Update Options.



Make sure that the firmware is up-to-date on the Triumph-3 / Triumph 1-M. You can use Base/Rover Setup to update the firmware on the Triumph-3 / Triumph 1-M. With the LS connected to the Internet, connect to the Triumph-3 by Bluetooth, then select the button below Start/Stop Base (it has the name of the base and rover). You’ll see an option for Update Firmware. It would also be a good time to update the radio firmware on your Triumph-3. This option is available on the same screen.


In Base/Rover Setup, you need to set your communications to:

Message Format: RTCM 3.2 MSM3 Short

Modulation: D8PSK

All other communication settings are according to your preference.

In the action screen, you’ll need to change the GNSS firmware to one of two multi-constellation firmwares: GPS+GLO+GAL+BDU 6Eng or GPS+GLO+GAL+BDU 2Eng. I believe the 2 engine version to be more robust than the 6 engine version. The 6 engine version divides the constellations by two’s into each engine (Engine 1 = GPS + GLO, Engine 2 = GPS + GAL, etc. ), while the 2 engine version uses three constellations in each engine. Engine 1 has GPS+GLO+GAL and Engine 2 has GLO+GAL+BDU.

If you use the 6 engine version, you can use the same action profiles you used with GPS+GLO (Boundary, Precise Topo, Quick Topo, etc.) If you use the 2 Engine version, you’ll need to make a copy of your favorite profiles and modify them because you only have two engines. So for the Boundary profile, make a copy of it and name the copy “Boundary 2 Eng” or something you can associate with being for the 2 engine firmware. Using a copy, instead of modifying your original, will allow you to use the original in the 6 engine versions. In the Boundary 2 Eng profile you’ll want to set the minimum number of RTK engines to 1 instead of 2 and set the number of engines for validate to 1 instead of 2. The same for Precise Topo. In Quick Topo (if you use it), you’ll want to set the minimum number of engines to 2 instead of 5 (since you don’t have five engines to fix with the 2 engine profile). You will also want to turn off Consistency since it only increments with 2 engines fixed, which can be difficult to obtain in canopy.

You’ll notice that downloading the base data at the end of the session will take a bit longer. That’s because your raw data files are now about twice the size because it includes raw data from two additional constellations. The good news is that DPOS is even more reliable with multi-constellation data than with GPS+Glonass alone. So the files are bigger and download times longer, but the results are much better as well.

Until the setting is hardcoded, we should also discuss the Maximum Signals and Maximum Signals Core 1 on the Triumph-LS. For the Standard LS (which this thread is for), I would set the Maximum Signals to 38 and the Maximum Signals Core 1 to 25. This limits how many signals are used by the processor. Too many signals will bog it down and you will see "No Data" frequently even though communications are good from the base. If you continue to see "No Data" interruptions, continue to dial back Maximum Signals Core 1 by 1 until the "No Data" interruptions become rare. Hopefully soon this will be hard coded and no longer necessary for customers to adjust.

The setting is accessed by long pressing the "Auto Setup Engines" button on the Engines screen accessed from the Action screen.

I've been using 30 and 30 on my standard LS's Shawn. It seems to be the sweet spot. Not too many code floats but enough signals that each engine will pick up three constellations.
 
Shawn, I've tried long-pressing the "Auto Setup Engines" numerous times with no result. The touchscreen has been calibrated and other buttons are working. I have updated firmware and software per your instructions. Does the LS need to be connected to the T3 with the T3 running as a base in a normal field situation for this menu to be available?

I think the long press of the auto setup engines is only on the LS+ running pre-release. I do not believe a long press of the auto setup engines does anything beside resets the engines on the standard LS.

Update to prerelease firmware. That's the reason why.
 
I'm still confused as apparently some users with a T3/'standard' LS setup are not having any problems and others, like myself, are. What is this 'pre-release'? software? firmware? How do I update to it?

That is very strange, it should work. Can you connect unit to RAMS to check it out?
 
Eugene:

I have the LS connected to RAMS. The password is disabled. Let me know if you time to look at this in the next few hours.

I have tred the Auto Reset button with the 2 eng (GPS+Glonass+Gal+Bed) engine and it doesn't send me to the other menu.

I had the same problem about 3 weeks ago.

Connect it one more time, please, I missed you connection.
