Always a fun one to try to explain the trespass laws to people who just don't get it.

Hi Garry, you are right about the repeatability being the true indicator. I'll link our repeatability video again here: kzbin.info/www/bejne/e5i9pqqBqN2AiKc. You can check out my comment to Niko, I am planning to do a more in depth repeatability video. It is logistically a bit of a chore, so there are some things I need to figure out first. (It is near the top of my list I promise, I am just very busy behind the scenes on a lot of other projects this year. We have completely revamped our support site at Survey-Assistant.com and that has been a lot of my time). For your Carlson unit (you are correct, Carlson takes the S631 and paints it blue) you can try enabling Hemisphere SureFix (if you have not already). This should eliminate any blown shots as it runs two units in parallel. (There should be an option in the Receiver tab in Carlson if I remember correctly, you can enable it like this in FieldGenius: kzbin.info/www/bejne/fGnZkmyubMumgsk) As for the other receivers, eSurvey, Unistrong and Stonex (I have not dealt with Qianxun, probably a similar story from my reading) they are all owned by the Unistrong parent company. Unistrong used to own Hemisphere, and these receivers all (about 2-3 years ago now) used a Hemisphere board. However with the CHIP act in the USA, Hemisphere was forced to be sold and is now owned by Case New Holland. The enclosure is the same, but eSurvey, Unistrong and Stonex do not have access to the Hemisphere RTK board anymore and use a Chinese board. They all use a Chinese Unicor board. I have done some limited testing on this board, it seems to be decent but I cannot comment on any repeatability (not enough time on the receiver, and some interesting results in my admittedly limited testing) or reliability (simply have not used and do not have any customers with those units). Let me know if you have anymore questions, Nolan

Hi Iztoniolo, the Hemisphere S631 does have a tilt sensor, check out my video on it! kzbin.info/www/bejne/rYSQhX9tnrKon68feature=shared

Often surveyors perform legal work when they are doing things like registering property boundaries, or submitting real property reports. At least that is what we want you to think.

Hi David, that sounds like a Message Type Issue. What is the Message Type you are using at the base? I typically recommend RTCM 3 MSM, but it may vary if you are using a different type of receiver.

Hi Andrei, We do have a video on repeatability: kzbin.info/www/bejne/e5i9pqqBqN2AiKcfeature=shared. However, we are starting to lay the ground work to create a new repeatability video as well!

Hi Letang, that is another great option (and works very similar to the known point setup!).

Hi Nikouer, we have lots of customers who have taken the S631 against the R12i and more receivers and had equal if not better repeatability in heavy canopy on the West Coast and SE US. We are always trying to get more receivers in, so I will add that to the list! The locations we selected for the repeatability test look less daunting on camera than they actually are but we have moved to these new locations in this video to increase the difficulty on the receivers. As for the repeatability tests, we have done a lot of independent testing that we didn't show in the video as it would be pretty dry (I'm not sure anyway wants to watch me sit in a lawn chair for a couple of hours). However, it has been on my list for a while to create a more comprehensive repeatability video based on lots of requests just like yours. It is a super time intensive video with a lot of data processing (and unfortunately I don't always have as much time as I would like for these videos as I do a lot of other behind the scenes work on support and sales). We do have a new video guy and I have started talking to him about how we can film this to make it both entertaining and provide all the information you want. As for the repeatability test, we are hoping to do as you suggest, see how repeatability is over time with shots compared to total station shots. The difficulty is finding suitable locations that are difficult enough near our office and that our practical to return to over various time lengths and are in locations that are actually difficult. The locations shown in this video are about 30 minutes from our office as we have to hike in. We are working on a more comprehensive video on repeatability so keep your eyes out. Let me know if you have any questions or ideas! - Nolan

Hi NSLRA, we should be able to get you that file. I will check and see if I can get the file for you.

Hi Luiz, we can definitely get this receiver in your hands, shoot me an email at [email protected]!

Hi Furio, we have actually tested the repeatability of the solutions: kzbin.info/www/bejne/e5i9pqqBqN2AiKc I am unaware of any RTK receiver that can get a fix indoors, but you are correct there is a lot of noise under canopy. That is why it is important to have a receiver that can filter out that noise. The latest RTK, whether it be Trimble or Hemisphere is definitely capable of achieving accurate and reliable results under canopy. That being said taking proper control measurements and checking your data is always recommended.

It looks like that pole emits gps coordinate where you’ll be able to locate exactly where that pole is. Think it’s to locate stuff that’s in the middle of nowhere

Hi Ahmed, they are GNSS receivers for land surveying. Will give you a position accurate to within a cm.

@@benchmarkequipment that’s so cool

Hi Tim, The Auto uses a uBlox chip (from what I can tell it is the same unit as the Mavic 3 RTK).

We can always help you establish your own network. Shoot us an email at [email protected].

Definitely the way to go, but there are still way too many guys using 12V batteries out there.

Hi William, always happy to hear from you! We are working on some more long form content and explanation videos. We will be trying some new stuff out, so make sure you let us know what you like. - Nolan

We showed it to Rene's daughters and they had the same comment and wanted us to name it the nail polish!

Hi Dingla, we do not use Carlson as often these days, but I believe that is the case. You can always enable and disable Grid to Ground and make sure the export changes.

Hi Jrr, not sure I completely agree with this comment. We do our best to provide the same conditions for the receivers. To do this we place our pole stand in the same location and place the receiver in the same hole on the stand. We do the tests back to back to ensure that this is the case and that any satellite change is minimized. We also use a base and rover setup with the same make and model as the base to give the receiver the best possible conditions. Both bases are set next to each other so there is no advantage there. Software has almost nothing to do with the fix time of the receivers. All RTK receivers compute a position on board the receiver, and transmit (in most cases over bluetooth) the position. The software does no computation towards the fix. It simply takes the reported lat and long position and translates it to the relevant coordinate system. On top of this, FieldGenius is not OEM software by Hemisphere. It is a third party company, much in the same way Carlson is a third party software company. As for accuracy and RMS values, in an effort to keep this videos shorter (I would love to make them longer and more in depth, but people don't watch that content and they are extremely time intensive to create) so we don't dive into the values here. However we did film a separate video on the accuracy and repeatability where we did do more of that: kzbin.info/www/bejne/e5i9pqqBqN2AiKcsi=DD4lx8Wq7pOnad9g. We have also done this test with many other receivers! Take a look here: kzbin.info/aero/PL-OAlKspUpSOWzetK0tAvypK6fOP_YuPb Let me know if you have anymore questions, or have any suggestions on how you think we can change the test! It can be a little hard to show the background work we do before the video to make the tests as fair as possible, and we have found most people simply aren't interested. Also feel free to email me at [email protected] if you have any questions.

This is also why we have a 30 day money back guarantee with all of our RTK systems. We stand behind our equipment and will more than happily put it up against any other system on the market, whether we do the test or not.

Hi Dan, no kidding when I started with the S320s we had to be really careful with where we set the base up! You can get away with the base in a questionable location these days, but it makes a big difference in performance if you set it in a good location.

Hi Tim, At the end of the day any receiver is capable of producing faulty fixes, including Trimble and Javad. This is why at the end of the day, the best tool a surveyor has is their own brain. As good as the modern receivers are, just like any instrument or technology you have to know the short comings and how to mitigate them (Might be a video we are starting to work on...). Javad and Hemisphere (others do as well), allow you to use multiple independent and unique RTK engines to significantly reduce the odds of a false fix occurring and is something I would personally recommend in a receiver. We have done some testing of receivers from China, including Unicor boarded receivers, CHC, Emlid and Stonex units. A lot of these units will use older Trimble or NovaTel (Leica) boards, and perform as you'd expect. The new Chinese boards can definitely perform well in certain conditions, but we have seen some odd results. I haven't done enough testing myself to conclusively say one way or the other if they are bullet proof or suspect, your mileage may vary. I won't name any manufacturers directly, but I would personally recommend staying away from the ultra low cost units, at least for the time being, especially for legal applications (if you are going to use them at least ensure you do take care and double check your results). I won't claim people haven't been able to achieve great results with units like this, they most certainly have, but really look into who is backing up and guaranteeing the technology behind the board. As for Trimble, we have done some comparison videos to both the R12i and R10. I haven't had a Javad come through the shop, although we have had some of our customers swap their Javad's for Hemisphere units. I haven't heard any complaints about performance when comparing the Javad and Hemisphere units, with the general consensus being the Hemisphere is easier to use for their crews.

Hi Reyar, do you have any suggestions? It is tough to get them where I am.

@@benchmarkequipment try it with chcnav,tersus,and comnav/sinognss

@@benchmarkequipment I love how you do comparison!

I will see what I can do!

Hi FranJaurro, it depends on the receiver (I believe they marked the Hemisphere boarded receivers as S900A etc.). Stonex can no longer use the Hemisphere board (due to the CHIPS Act in the US, as Hemisphere is an American entity) and are using Unicore boards moving forward.

Hi Boss, In these tests we generally use Normal Fix mode.

Thanks!

Hi Gold, Unfortunately, that feature has not been brought into the Android version yet. Your best bet is the Traverse tool for now. You can compute the angle between two points and use the X..Y notation to fill it in FieldGenius. I'll let the guys at MicroSurvey know you are looking for this feature.

@@nolanbetzner5313 Hi, thanks for getting back to me. I just read my comment again and I noticed something doesn't make sense: "i can't find this option" should be "I can't find some options". Sorry for that, I hope you can feel how frustrated I am, i didn't notice my mistake. There are many options missing, the above is one of them. I got in touch with the company we bought the controller from, they said they will look it up. I've sent an email to MicroSurvey, waiting for a response. What really bothers me the most is that we were supposed to upgrade, not to downgrade our tools and I read somewhere that the new android version has all the core features of older versions. Thanks again for your effort. I really appreciate your help.

Hi Gold, Not sure if you purchased from us, but I typically don't recommend upgrading from Windows at this time especially for full blown land surveying. Android is definitely the future, but it is still (extremely optimistic estimation as of 06/24) a year away from being "feature complete". It is tough, as there a lot of awesome android data collectors out there. The good news is they are updating it quickly but I don't have a timeline on that feature. I know they are working on adding math operations in fields (X..Y - 90 etc.) but I have no timeline.

@@benchmarkequipment unfortunately for me, we didn't get it from you. I live in Greece and my company bought it from a shop that have business with. I asked for upgrade because I use an old Foif controller that, among other problems, had all it's batteries bulged, I was afraid that someday they will explode. Couldn't find replacement batteries, equipment was old so I asked them to get a new one.

Hi Gold, unfortunately for the time being you'll have to hang on, or find another Windows tablet. Let us know if we can help with anything.

Hi Hando, you may be able to use the arc tool to place a center point however, you may need to use a method similar to the one described here: www.instructables.com/How-to-find-the-center-of-a-circle/. You can use the intersection tool to find the middle. studio.kzbin.infoCyWEPo6QVl4/edit?c=UCADMr1fMZsUMGw1HEGcQwiw Nolan

Hi Boats, the biggest difference is the Athena RTK engine. It is what is filtering out the good and bad signals to give you the best performance. You should check out the video comparing the S321 to the S631: kzbin.info/www/bejne/fp-3lWSDr6pkbrM!

Hi William, glad to hear from you again! I have some more stuff planned this summer (just need to find the time). Keep your eye out!

Hi Kailey, do you mean over UHF or an averaged position? I am not sure what you mean by a here solution.

@@benchmarkequipment exactly! The average position

Hi Kailey, and this is with a software like FieldGenius or the Desktop software? Sorry for the late reply, KZbin hid this in already replied.

@@benchmarkequipment I use fieldgenius for android. I know how to log raw data, I've used this video to configure the rover for broadcasting. I guess the missing part of the equation is to setup on the average position and post process the data. Thanks for your reply and thanks for your videos :)

Hi Hando, how did you create the line? When I have a line drawn in FieldGenius between two points, it has no issue staking the elevation of the line. Also what version are you running?

Hi Mule, what receiver is this for? We have a similar video for the S321 and S631.

Hi Orenadler, that is dependent on the network you are using. Try looking for one transmitting RTCM corrections. Preferably RTCM 3.2 or RTCM 3 MSM.

Hi Nate, You should be able to set the antenna height option in the WebUI (that is how it is for the S631). If no option exists, it should be until the bottom of the antenna mount.

Thank you for the reply - I used a measurement to bottom of antenna mount and it seems to be working correctly when checked.

@@nate866 Glad to hear it! I believe the Rinex convertor automatically adjusts any elevation to the bottom of antenna mount measurement.
