Wondering since I hadn’t seen anyone mention…how well is Galileo helping? I’ve noticed a pretty good bump in performance in our R10s. Checked a newly updated set against one that had year-old firmware and there was a noticable uptick in speed and ability to fix. It seemed to make better use of the Galileo SVs in the solution.

Although the Javad Triumph-LS is equipped to use Galileo signals, I think most of the systems sold to date use a Triumph-2 base station, which doesn’t have Galileo capability. I believe that a T1M or Triumph-3 (not yet released?) — or another Triumph-LS — at the base is required to use the E signals, so a good chunk of Javad users (including me) can’t answer your question.

Javad has not released an update to allow the receivers to utilize Galileo yet, its reportedly still being tested. I have a Triumph-LS and a T1m base, but it will require a fee to be paid to utilize Galileo.

Looks like one could try a GPS/Galileo solution if the receiver tracks both. I still haven’t actually come across a positive statement from any manufactures about using it in a solution. Some seem to imply, but not direct statements. Being able to use the signals is still pretty new. FCC finally approved use of all but E6 in the US end of November, and the EU contractor below only got this beta going end of October.

Maybe all we need is a smartphone:

In the last 12 months I have upgraded my gear, now using a pair of Topcon Hiper VR’s and pair of Sokkia GCX3 that all access Galileo. My backsight checks with Robotics vs GNSS has gone from ?ñ0.04′ to ?ñ0.01′, using the same procedures, just different gear. I now see an average of 15-20 SV’s all day. The Topcon Hiper VR’s are supposed to get BDS, but I have yet track a single BDS satellite. According to mission planning, there should be a few out there. When I tested the Hiper HR over a year, I was tracking upto 3 BDS satellites.

It’s worth noting that a receiver’s the ability to track SVs from a given constellation doesn’t mean that they’re being used effectively in the solution.

“access” This is the same sort of language I can find from manufacturers. I don’t know seems like they would spell it out if they had the capability. I think all of the new stuff is getting better with or without Galileo. So I’m still anxious to see someone come out and claim unequivocally that they are using it in the solution, and then be able to test against not using it. There’s more GPS L5 for instance now, so might be seeing improvements in position from that as well as updated algorithms for dealing with Glonass. I’m seeing 15-20 or more but still times when only 7-9 are usuable (can only use 8 best), so seems room for improvement with galileo if they show up at the right time.

I haven’t tracked Galileo with an R10 yet, but as a general rule the RTK rover only displays the satellites that are being used in the solution once you start a survey. For instance, if I start an RTK rover while tracking 8 GPS and 6 GLONASS, it will display 14 SV, but if the base isn’t tracking GLONASS it will drop to 8 as soon as I start the survey.

Jim, Good point – Most vendors say they ‘track’ but are silent on what they use in their RT solutions.

That would be very deceiving and useless if “most” vendors did that.
Topcon Magnet Field identifies SV’s as Visible, Tracked and Used in the Status area. On the Topo and Stake Out screen, it shows Tracked and Used.

Our RTK gear purchased in 2013 came ready for multi, but at that time running SurvCE 3, only used GPS and GLONASS. A couple of years ago via firmware upgrade of the base and rover, plus upgrade to SurvCE 5.0 (to get RTCM V3.2), we are now running on 3:

I know without a doubt that my R10s are “able” to track Galileo and Beidou and “are making use of” the SVs in the solution. There’s no guessing to it, Access shows a “–” next to SVs being tracked but not used and a “check mark” next to those in the solution. Even the older R10s make use of it, but their firmware is older and doesn’t see quite as much an uptick in improvement over the units I updated with the newer firmware tweaked to (seemingly) be a little more “modern signal centric”. Which is to be expected because the last several versions of firmware release notes say “GNSS signal tracking & processing enhancements”.
I can also tell you from head-to-head comparison that more Galileo is more better. This was determined using one R10 rover directly compared to another in which I purposely disabled Galileo.
