Acess TSC7 -R8i slow?

  • 1.  Acess TSC7 -R8i slow?

    Posted 09-20-2023 08:05

    Hi, here again with a bit of moaning..

    the other day I borrowed a Lecia GPS(the tilt version) and a cs20 handheld, what a difference to the access/r8i in terms of time to register a measurment. So how can the TSC7/access be so incredebly slow to register a measurement, even set to quick measure within access it still takes 2-3s to register, something is not right I think. The cs20 is a almost 10year old handheld(?), the TSC7 2years max? the cs20 registers as you press the buttom, instantly, the TSC7 as said 2-3s, how can this be? so equipment is slowing me down, is there anything one can do to the access/TSC7 to make it register measurements faster/instantly ?

    Cheers!

    I don't know that I have the answer, but keep in mind, the TSC-7 / Access combination is taking several shots during that 2-3 second period, and averaging them out to minimize any motion or leveling errors occurring during the shot.  I don't know what the Leica is doing but perhaps it's only taking a single shot?  That would make it faster, but not necessarily more accurate.

    I believe there are averaging settings in Access you can adjust.  Also the TSC-7 tends to slow down as your hard drive fills up.  Try to backup and archive project files as often as possible to a network drive, USB drive, or portable hard drive.  You can always put them back if you need them.

    I understand your frustration.  Please let us know if you find a solution. :)

    The fact that Access takes 2-3 seconds to store a point is related to fully configurable Access settings.

    In Access you can set up MINIUM amout of epochs you want to capture with predefined accuracy (from 1 to 9999) and MINIUMUM amount of seconds you want to observe a point (1 to 9999).

    Set it all to 1 and enjoy your fraction of a second, no double checking, no confidence, immiedetly saved point (apparently default Leica settings).

    i would like to agree with the first post. i think there is something funny and slow going on with access. 

    we are running tsc 5 with access 2023 latest version and sp80/85 heads. i have the settings down to one second and use rapid point where i don t think it asks for an epoch setting. not sure there. but topo point with 1 epoch is even slower for sure. 

    so i noticed the slowness when first switching to access but also sort of put it aside as the software getting better solutions. but last week i worked side by side with a colleague using tsc3 and survey pro and the same head same of a common base. he could collect almost twice as many points than i could. it is pretty much instantaneous when you press the button. 

    to marian s point about quality. sure when you are shooting a hard surface, it is nice to have higher quality. but when topoing rough terrain it is rare that mm or even and inch is going to matter. the issue here is that we are not finding a way to drop access to the fastest collection speed and forgo the quality a little when the tech is out there to do it. 

    on a slight side note. we run rtk and logging and have to have logging at 1 sec in order to collect 1 sec epoch data on control point shots. for a regular rtk shot. with survey pro you can have the head record at 5 sec intervals and still shoot rtk at 1sec. so we get large data files for no reason off the head. 

    thanks.

    BC, yes I think the amount of free space in the RAM/storage is a factor aswell, my device was fairly "packed", cleaned some out and yes, its a bit more responsive now, as far as poking around in the GUI goes. It does not however change that "slowness" of GPS measures to any greater extent unfortunately. 

    Marian, I did have a look at the settings for the GPS, cant duplicate what your saying, the quick measure(the detail measure has some PDOP etc one can fiddle around with, but nothing for the quickmeasure, which isn't all that quick....) has no setting to adjust within the measurement profile(not that I can find anyway), where is that setting within the access? Have you done this with a TCS7 & access??

    Ian, I totally agree, does not have to be all that "accurate" for just about anything I'd say(even with quility check of this and that, how precise could it be? +-50mm, 100mm?). If one does want some better quality from the GPS, a average point of say 20-30 measurements is what I mostly do. If precision is required then use the total station. The GPS is not really to be trusted with better accuracy than +-50mm if you ask me. I also agree that as things are now, a Leica or a older Trimble would be about twice as fast for the type of work I do, would really like to hear what the developers has to say about this?

    Cheers!

    Yes, Access.

    Edit Survey Style.

    We are using 4-5 years old TSC7 v1 with Access 2022 or 2023

    Thanks Marian, I did just had a look at the settings/measurement profiles/GNSS R12i/settings for rover/ (I have a swedish language GUI...)

    in the first pic is the settings for rover, cant see anything about minimum epochs seconds in there ?

    second pic, if in measuring GPS mode and choose "rapidpoint" method and option at bottom screen, this is what I get, no epoch 1-9999 (?)

    third pic, in measuring GPS mode and choose "detailpoint" method, and option at bottom screen, no epoch 1-9999 there either (?), have tried setting this to 1 way back when I first got this equipm, and it has no real effect on measure time/registration

    3rd screen is the one you're after.

    Detalij punkt. Set QC to QC1 only.

    Mattid set to 1 second or 0 seconds if possible.

    Antal matningar (epochs) set to 1.

    Automatically save the points, do not prompt for attributes, do not see before storing.

    Turn off tilt corrections in R12i.

    It will be instantaneous.

    P.S. You guys are still running on SBG Geo in Sweden? Leica Icon software reminds me of it big time.

    I used to service my jiggers at Trimtec in Kista when I worked in Stockholm in 2011.

    thanks, Marian, will have a look into this monday morning. So one difference btw Leica/Trimble right there is that Leica stores with tilt active. By Leica I mean Leica hardware, and running SBG Geopad(the feild computer software from SBG) or Leica captivate(which I've never used properly) software for feild computer. Yes, many ppl here using SBG's software, most projects I've been in has been SBG Geo oriented. Will try monday and see if these settings speed things up,

    Edit, Ok, so it took a few more days for the test, I can confirm that it's faster the way you describe it, but not instant joy, at least not for me.

    I'll call the local support and ask(did that several times when I first got this setup, but of sorts gotten used to the "slowness")

    Btw, about using third party software on Trimble, that would be a real advantage, using access when that software has advantage over for ex Sbg geopad and vice versa. How come Trimble isn't open for 3rd party software?

    i notice that on ours for rapid point you don t have too many options. just QC choices. 
    but for topo you can chose how many epochs which i tried to put to 0 but it does not allow that. but there is also a time option. i had it at 1 second. but with marion s advice i see that it can drop to 0 seconds. i will try this and see if it makes a difference for us next time i am out. 
    also in our case we are running sp85 or sp80 at the base and sp85 usually at the rover. and like mentioned before survey pro is instantaneous side by side on the same survey with same base access is way slower. but sure hope this 0 seconds will make the difference. thanks.

    so i changed my topo point settings to as low as they will go. 0 seconds and 1 epoch. no tilt. QC1 only. this is still taking about 2 seconds to shoot. ironically you can watch the timer count up to two seconds when it is set to store on 0 seconds. i believe there is something wrong and we should have the option for instantaneous shot.
    rapid point is slightly faster than this but still not as fast(instantaneous) as survey pro with the same sp80/85 heads and likely the liecas brought up in the post.

    i will reiterate again that i got used to it being slow and do like the tsc5 data collector. but then happened to work side by side with someone running surveypro and was blown away by the speed difference. for those thinking: who cares about a second here and there, we are talking about a difference at the end of the day of maybe 750 points compared to 1000 points collected. this is a significant difference. i know i used to collect over 1000 points often on a topo day with survey pro. but can not remember doing that with tsc5. this is a serious problem.
    thanks

    Ok, did have a talk with the local Trimble support, they are going to investigate this slowness phenomena a bit, so I guess it's going to be alright in the end, whatever solution is doable. Also mentioned the 3rd party solution: -not going to happen, was the short answer to that. Personally I dont see why not(?), Topcon/Sokkia/Lecia/ etc etc, are all open to use with SBG Geopad. I'll get back with the verdict from the support,

    thanks kare, it occurred to me that some people might read my posts and not understand why i keep talking about survey pro and spectra precision heads. trimble owns spectra and is phasing our survey pro. the trimble team should have this gear available to them and can easily reproduce what i was seeing, and run some quality control tests down some pavement too, if they are so inclined. i have a feeling that the slowness translates over to the r12 as well, from what kare is saying. we had some r12s a bit last year and i do not remember them recording a point any faster. we were on the fence to buy them so i think i would have been attuned to anything that was significantly better with them.

    Ok, so Trimble tech support says that nomatter what you do you will not get instant point registration, it will take around 1 second(support tech talked about 0.2-0.5 sec), so yeah, no real joy whatever you're settings are, you will not get instant registration. I guess the other solution(Leica etc/Geopad) & Trimble of older versions(?)) just dumps whatever the current GPS position/solution is at hand onto memory storage, ie instant registration, whereas TCS7/R12i in it's current setup does require user to do a measure by pressing enter. So... it is what it is I guess. Access has a lot of nice features, and a few thats very much missing for the type of work I'm doing at the moment.  I'll probably switch to Sbg geopad & compatible hardware when the chance to do so arise,

    Cheers!

    Logging data rate for RTK + logging does not need to be at 1 second. I assume you are logging in your base only and  not in the rover?  Just today I was logging 10s at the base while observing RTK with my rover.  Logging rate is purely for static processing and doesn't need to be 1s just because you're using your rover RTK.  Logging data at the base is an extra function that doesn't affect RTK functionality.

    thanks robert.
    not sure i agree about pressing the button and moving without confirmation. but it should be easy to test. i might try today. likely can get a meter away on a rapid point shot. and don t really think a 1 sec(epoch) shot on topo mode will even store with me walking away. but i will give it a try.

    so for the other comment. i guess i did not lay it all out. we record 5 sec on the base head. and i would like to have the rover head record 5 sec as well, but if i do that, then in an rtk shot it only records every 5 second epoch skipping over the epochs between. a regular 30 second shot becomes 150 seconds or something in rtk. so to get around this i drop it to 1 sec. this is a flaw in access because the head should be able to record what ever and rtk record normally.
    we record on the rtk head because we are often far in difficult terrain and sometimes questionable tree cover. on challenging corners even when we have rtk radio and a fix solution we will sometimes record for 5-15 minutes. having then the option to also run a post processing solution on the shot. although i do not fully grasp the math behind rtk vs post processing, my understanding is that it is a different solution and so it can be used to validate the shot. but please fell free to me know if this is not the case.
    also just to be clear, from what i have seen, a static shot with poor sky view will not always give a good solution, even if it is run for a long time. sometimes it will work, but not always.

    What is a R8i from Trimble?

    From my experience, once you press the "store" button (be it robot or GNSS) the observation is finished and I move on.  I don't wait for the audio telling me observation stored. It's more of a data communication of data to get the "observation stored".  You can use a "rapid point" which is faster but it's said about a 1 in 10 chance the data will be bad because it's all singular observations with no redundancy.

    A topo point in Trimble Access with a R12i will take about 2 seconds to measure. If you want something faster that that try measuring a rapid point.

    thanks James, but as mentioned in first post the measure mode is at the fast/quick/rapid mode (whatever that means, it's anything but quick..), still takes about 2sec to register a measure with the GPS. I did ask about this about 2 years ago when I first got this equip, both at the local support and here at this forum, all saying,: -its great just use it as it is. Someone(here at this forum) brought up that old Trimble handheld/GPS eqipm was way faster to register a GPS measure. How can this be? Users just go: yeah, this is new equipment is just great, it takes a long time to register a quick measure but it goes: BING afterwards! If someone has some instructions to make this R12i/Access fast, and by that I mean instant registration, please post that here, thank you.

    Kåre, Rapid measure with the IMU on (tilt compensation) takes slightly longer to measure than with IMU off. So a 1sec rapid shot really becomes more like a 2sec shot, Its the price you pay for not having to hold plumb!

    Ok, thanks Michael, makes sense somewhat, but then again Leica equip(also tilt) does register GPS measures instantly, with tilt active. So what's going on with the Trimble software/hardware then? What is the Lecia software doing that Trimble can't?

    robert. i had a chance to test what you mention about pushing the measure button and then moving. i was using rapid point and tsc5 and sp85 head. took one shot on the ground and waited for the confirmation sound. for the second shot i pushed the button then lifted the pole, lets say at a medium speed, not erratic but not real slow, as if moving to the next shot, but i went vertical for simplicity. got 0.5 m difference in elevation on the shots. there is a chance you can get away with push and move with total station, but again not something i would trust.

    some side notes to this. i think i have QC1 selected. i have not played around with changing these options to see if it stores faster. but from the help portal, these refer to what quality stats are stored with the point. in theory the coordinate could be stored right away and this info could follow without slowing down the work. if this is the problem?
    also i notice that sometimes when storing in rapid mode under canopy i will get a warning that position quality is not great. so there is some quality control happening in rapid point.

    Another thing to consider is the "Solution Latency". If you are using the same reference station and radio, this shouldn't be much of a difference between the 2 receivers. If you are using an RTN for the Trimble, and a radio for the Leica, then you will definitely see a difference. Radio correction latency is usually under 1 second, while an RTN latency can be several seconds. Trimble Access can display its correction latency if you tap the correction icon (I think).

    Another aspect of solution latency is the measurement mode of the RTK receiver itself. Typically, we are roving in "Low-Latency" mode, where the receiver is using its last correction almost instantaneously. When we start an observation, it goes into "Synchronous" mode and the position solution waits for the same epoch correction to arrive. This allows for smooth response when roving, and more accurate positioning when "static" and observing a point, but will cause a 'lag' which can be a couple of seconds depending on the 'age' of the correction.

    I don't know the specifics of your settings or Leica's, but I suspect that solution latency is your issue. If you are using a different correction source between the 2 systems, then a comparison isn't valid. I don't recall if a Continuous or Rapid point is "Low Latency" or "Synchronous" by default. If the Leica receiver is using whatever they call "Low Latency" mode when the Trimble receiver is in "Synchronous" mode, you will see at about a 1 second difference in when the position is computed. If you are

    O, thanks Dave, in this case both Leica/Trimble are using  network RTK, no radio on either. Not sure what solution latency either Leica or Trimble are using, is this something that you can change as a user? I cant see any such options for the quick measure mode options, there is quality control & precision options, have fiddled a bit with those but no real sucess with that.
