Things that J-field needs

John Rosco asked about things the Triumph LS Needs.

Well, I have found a bug in intersections.

P1 is inside the radius.
P2 is the radius point.
and it refuses to perform a proper BRG DIST INT.

That needs fixed. I worked it out via trial and error, in the field. Because of a bug in the software.

Your product is unfinished, if B/D int does not work.

Also, I need acreage to work around curves. Multiple Curves. and Reverse Curves.

And, I need it to allow MANUAL point number entry.

And, allow me to STORE these sequences, for staking polylines.

OK,

OK, until it's fixed, you can:
Use CoGo Basic, to MAKE a new coord, that is OUTSIDE the radius, (On the correct Brg. , for the B/D int) then do the B/D int, using as a direction the point that is outside. Now, it seems to work fine.
I did not know this yesterday in the field. IF I had, it would have improved things greatly. I banged my head on a tree, until I gave up and used Trial and Error, and got it within 0.02', and set the corner. Stuff like this should be fixed.... Now, if I knew enough, I'd do it. But, I don't.

I checked the Bearing-Distance CoGo function and agree it does now properly.

And, I need it to allow MANUAL point number entry.
If you are referring to manual point number entry for staking points this is done with the Target white box.

And, allow me to STORE these sequences, for staking polylines.
You can select a list of points to stake by using the "Select Points to Stake" in the "Stake Points Mode" screen.

It fails IF the Bearing Origin point is inside the radius. It works if the Bearing Origin point is OUTSIDE the radius.
Thanks
Nate
It does not produce a solution in this case but I also found the bearing is calculated from calculated point (P3) to the P1. The diagram shows the bearing being from P1 to P3 so it is wrong by 180 degrees.

It did that too. But, reversing the direction had no effect, in the field recently. (I actually tried that). I wound up using trial and error, and got it... close enough, to set a corner. But, in the office, the only way I could get it to compute the right coord, was to use a P1 outside the radius.
Thanks

Another thing that would be nice to see improved in JField if possible. I realize that surface staking does work with a small file. Like less than a half of 1MB. For instance, today I have an XML file of 3.3 MB (not that large) and uploaded to J Field to stake out a couple of points on the surface. It took at least 5 min. to upload before I could use it. Once I get it to work you had darn better not back out to do something else because it will take you the same 5 mins. or more to get it going again an then it drags like a snail. When I put that same file in my Mesa 2 (5 or 6 years old) running Microsurvey Fieldgenius it came in within 30 seconds and I could stakeout points with the Robot within seconds. It must be a memory issue with RAM allocation or something. Is it a hardware or a software issue. You tell me. I like how it works when it is working smoothly with a very small file, just needs improvment handling bigger files because all surfaces are not a 1/2 Acre site.

What I'd LIKE is a full duplexing radio repeater.
It can Listen on Channel A, and broadcast on Channel B. The LS is modified, to LISTEN on several channels at the same time. So, you can daisy chain several repeaters, and get all the range you want.
We work in MOUNTAINS. We tend to move our base around. But, if we had a repeater, that was around 4-15 watts, and could drive those signals down in the holes we work, it would be VERY much used.
How to use? Just go to a hill, where you get loud and clear base signals. Set up the repeater, and it is as though you had moved your base.
But, the LS receives on another channel, than the base is set on.

Nate,
We've done something similar to what you're asking. John Evers helped getting the settings correct.
You can use the internal radio to send the signals at 1 watt.
You can then set up the 35 watt radio to receive and repeat that signal at 35 watts on a different frequency.

I got it to work a couple of times, but sometimes it wouldn't work. I was sure I had the set up exactly the same, but it was inconsistent.
We normally just try to move the base now.

If you have cell at the base, you can use a Jlink radio to receive the cell (TCP) corrections and repeat those to UHF.
We have that and use it often where some of the site has cell and some doesn't.

Ok... IF you can use the 35 Watt, as a REPEATER, on another channel, Then.... Can you use a 35 watt radio, on the base, and set another 35 watt radio up as a repeater?

Are you using the 1 watt on base, just because you HAVE one, and you don't have two 35 watt ones?

Or is this for some other reason?

This kind of advancement is integral to us country surveyors....

Thanks

Nate,
We used the 1 watt internal base radio with an external antenna on a 15 ft pole. I do have 2 35 watt radios, but if I remember correctly you couldn't set the parameters for repeating the signals in the 35 watt radio at the base.
Maybe one of the Javad guys can confirm.
When it works with the 1 watt base radio it was awesome in the mountains. The external antenna on the pole would actually reach a long way. Then the external antenna on the 35 watt repeater would receive signal stronger than the LS.
The last project we used it on worked great on our initial field work. Then when we returned to stake lines etc. It wouldn't work and luckily we could set another base to reach some trouble areas.

Hi guys,

Please remember that for the 'base' to send UHF RTCM RTK corrections, the RTK correction messages take a several hundreds milliseconds to be transmitted over the selected UHF channel.
Thus, any 'UHF Repeater' radio modem ( in 'listening mode' ) needs to receive the 'base' UHF RTK RTCM correction data,
then turn itself around and 'transmit' the same RTK RTCM correction data to the 'rover',
then switch back to 'listening mode'.

Thus the 'base' TCPO RTCM RTK correction transmission interval needs to account for the entire data transfer period.

Thus when using a HPT435 repeater: Set the 'base' TCPO RTCM RTK correction transmission interval to be 2 seconds or more so as to allow for complete 'base' to 'repeater' to 'rover' UHF radio transmission of RTK RTCM data to complete.

(Using a 'base' TCPO RTCM RTK correction transmission interval of 1-second, can result in 'loss of complete RTCM corrections)

Finally: Do be aware of the UHF radio signal travels as 'line of sight' and that the 'radio viewshed' and 'obstructions' will be in effect.

Matt, I have heard that you are IN PERSON a really nice guy.
BUT, on the internet... you are a trolling hateful guy....
BECAUSE you don't say enough!!!

And, you expect US peanut eating morons to know more than we do!

TALK! TALK TA... I mean tell us MORE!!
That's the NUMBER one problem with RTK - RTPK GPS... Base Rover coms.

PLEASE tell us perzactly what you mean. (you have set my imagination aflame) God knows, My 'magination goes all the time.
So, you bait me, and leave me hanging.......

I'm shaking.... and holding my check book. .... er credit Debit card...

Where can I get FULL cell corrections, anytime, anyplace......

BAM! I'm in!

If you are ever in Arkansas.... I will buy you a meal, to get to hear what goes on in your head.....

Cause this sounds like a great idea.

Ha I will work on saying more. Starlink data service is expected to start next year in 2025 and it be exclusive to T-Mobile customers the first year. T-Mobile customers will have texting and voice and data service anywhere on Earth. For surveyors this should mean that you can setup cellular corrections anywhere on earth if you T-Mobile hotspots or SIM cards.

I plan to be posting updates about this on my LinkedIn page. I'll let you know if I'm ever Arkansas!

Let me know if you make it to AR to and I'll show up. My 435BT radio is the Achilles heal of my system and has been since day 1. My brother has a unit with a little internal 5w and works circles around me in the mountains. It's quite embarrassing.
