> I wrote my MS thesis on gps under canopy. Give me your email and I'll send you a copy if you're interested.
Oooo ooooo.... (waving hand franticly) .... send me a copy too. 😀 Please.

That's a common belief among non-Surveyors ...
LOL ... I had a Sokkia Salesman tell me the same thing about 10 years ago ... but I knew better at the time ...
Me too please!:-)

You got that right. I was waiting for you to chime in. I would like to put on an all day seminar at Myrtle Beach State Park. You think we could come up with one? I would like to run a conventional traverse with total station with all but a couple of points under canopy. Let me know what you think. It would probably generate some good data for comparison.

It was a good read.
It was a good read, and confirms in a much more formal way what we have experienced.
We have taken shots under canopy and then traversed in to check the shots. They have never been good enough; and were off in the same ranges you report. Hopefully time, more satellites, and better antennas will make it possible.
Thanks for sharing your paper.
Stealth technology
One of the hands remarked the other day that if they could cover an airplane with cedar branches they'd have the best "stealth" ever. No radio signals can ever get through them..
Yeppers, that sounds like a good read, include a copy to my mailbox too....
I saw this post this morning and figured he would get the replies he did...be nice is trees were not an issue, thats when a person really needs it..
I am in Search and Rescue and one of our members sends me links to interesting things...here is one on GPS indoors????
Interesting. I've always wondered if it were possible to make ground based transmitters that work like GPS on wooded sites. Like you set 3 or 4 transmitters up on control points around your site, then you could walk the site with a rover, getting your position from the ground stations. It would likely only be good for X,Y, though ... no elevations.
