Field Procedure, Staking a line, in the thick stuff.

Staking a line through rough, hard to RTK locations.
Using a telescoping 12' pole.
Turn on the light on the bottom of the LS, to flash with the sound.

I think of it in terms of BALLOONS. At the circus. A balloon is a "Conjunction of Satellite data, where a fix is to be had".These Balloons are 100% available, out in the open. But, the denser the woods, the fewer and farther between them they are. Some are small, some are large.
Your typical fixed height rod is simply sitting there, WAITING for a Balloon to come over the GPS antenna, on top the LS. When one comes over, it starts pecking.

What we are going to do is to GO LOOKING for a balloon. When it finds one, it will start pecking. It is a more aggressive method.

Use float, to get close. Typically, 2-5 ft.
Press start.
Slowly raise the pole, until it gets a shot. Let it stay there. Sometimes it goes all the way up to 12' before it starts pecking away. Sometimes, it has to come all the way back down, before it finds one.
This method of Raising and lowing the rod, LOOKING for a conjunction, (Balloon) is a more efficient method in the woods.
Granted, once you find one, you have to stay put... because it will be forced to JUMP FAIL if it knows you moved.

HOWEVER, this brings us to another point.... IF the LS had a method of measuring REAL TIME the Height of the Rover rod... it could avoid a jump fail, due to the changing height of the LS.

This way, you could hypothetically raise or lower the rod, to "Find a balloon", then when that balloon passes, go vertically searching again, for another balloon, without inducing a jump fail.
It really could make staking a line faster.
OF course, it means you will HAVE a bad elev, unless you edit the height of the LS, from the POINTS MENU after the shot. BTW, I really MISS the old way, which ALLOWED you to change a ROD HEIGHT before storing a shot.

Kind of like we are allowed to change the POINT DESCRIPTION before, during, and after a shot.

Anyway, it saves time marking line in the woods.

Go looking for a balloon.

BAM! we are good!

Nate...keep the info and enthusiasm coming. So far the Triumph 2 and LS have treated me good. I am over 50 and I see where a young surveyor (whippersnapper) mentioned in a recent survey magazine that his next purchase is going to be a Javad GPS......so we must be on the right track....I read the whole story..that guy can hustle thru the woods with a total station....Phil

This was a bug and epochs were not being adjusted after the antenna height was changed so that's why it was blocked.

Ahh I see... well, I am thinking... it would be (in the over all big picture) good to be able to do that... because, someday there will (I hope, I predict!) be a bluetooth device to read the Antenna height, in real time, before, DURING and after an observation. I have tried to come up with how, and have several ideas... Cheap one is a duct taped leica disto, under the LS, and a small plate near the rod bubble, with a few constants...
Anyway, it would be nice. (The duct taped disto, is just an illustration, that the tools are around already...)
Progress.
Keep up the good work.

Ahh I see... Someday, the antenna height, will be an automated part. Meanwhile, it would be nice to have the ability to change the antenna height, before storing, just like modifying the point desc.
