LS Trajectory Settings for use on a Quad

I am performing a survey on 250 acres for contours. Please provide recommended LS settings for using Trajectory on a Quad. My general questions are:

1. Setup of the LS
2. Radio Configuration
3. Acceptable Speed of Quad to collect data
4. Making sure the LS will accept an point when out of level.

Thank you,

Brett

Hi Brett, I mount the LS to the ATV, you can connect via rams on a tablet if you need to see the display or use an external antenna. I just set mine up and let it run with no real need to see the display.

2. Radio Configuration

Beast mode.


3. Acceptable Speed of Quad to collect data

I LIKE 2 to 4 mph depending on terrain, terraces, and what not.


4. Making sure the LS will accept an point when out of level.

I don't worry to much about the level of the LS. If the pole is leaning when on a slope that means the ground is lower too.

Thank you,

Brett

Adam,
Thanks for the reply. Does the LS accept a shot when out of level while using trajectory? I hope so.


If there is a lot of slope you may want use the option to adjust for the plumb being out. Most of what I have done was lightly sloping or flat. My LS is in the shop in San Jose so I don't have it in front of me for reference.
 
Thanks for the advice. I am on fairly flat land for this project. I wasn't too concerned about elevation due to slope. I am concerned about
taking a shot when out of level. When using Point Collect, the LS wont start when it is out of level by a certain amount.

Yes, it does. When collecting a point without Correct for Tilts, the LS has to be level within 5 degrees but this limitation is not imposed when collecting a trajectory.

I think that when u use trajectory you have to be level to begin, Then after that it doesn't. Trajectory stores all the shots under the trajectory so u don't have to start for each shot taken. I wish I had mine with me, I could be a little more certain. By the way, topo with A TV is the way to go. You will like it. I set the trajectory to store every 10 to 20 feet. Another thing I find useful was mounting the LS to do trajectory and store ground shots and leave it running. I mount another receiver and use a data collector to shot ground breaks and other features simultaneously. One receiver all ground, one receiver for detail. It provides nice topography. I use a gator and put the LS on the passenger side, and the other receiver on the driver side.

Brett, Set tracking loops to fast when using the atv. I think the setting can be found under Set up, then Advanced. I have noticed i get a few bad shots every now and then when riding along. I've seen this with all brands of recievers that I have used, It happpens. Speed and bumpiness play into it. It's more likely to happen when you are up against the edge of the woods. You can catch these few bad shots by contouring at a 0.1' contour interval, that undesirable shot will stand out. This is another reason I run two receivers on my rig. You get two shots the width of the atv apart as checks. Good luck, set back and enjoy the ride man!

Now that is the first time I have head about anyone running two receivers. Very interesting concept. I assume you are running 2 data collectors also. You should post up a pic sometime, seems interesting. You must do a bunch of ATV topo to go through the trouble of a setup like that.

I set the LS up on the mount on the passenger side, start trajectory and just let it collect ground shots. On the driver side I use a data collector mounted near my left hand to be able to quickly change codes when detail such as groundbreaks, swales, top of banks. I don't have any pictures, next time I am out with it I will snap a few. Also I like to have the LS using the T2 base for corrections and the reciever on the driver side operating on a network VRS. Two independent means of getting a solution.
