Hello. I just got a Magellan Promark3 (2 receiver set) and have used it in a couple of surveys. I am having problems getting all my points 'fixed'. Usually 50% or so end up 'floating'.
Does anybody have experience with this and how might I overcome the problem?

Also, in uploading my surveys to the "GNSS Solutions" and exporting to a DXF looks to be fine and all, but when I import the DXF file into Autocad, the plan view looks to be alright, but scale is way off and when I view the points in 3d or in a different view orientation, the points look to be all in the Z axis, or all stacked on top of each other in a line up and down. It doesn't make any sense.

Thanks.

i have countless hrs of training on the promark 3's i would love to help. my email is [email protected]. it would help if you would post the sequence of your setups, one base and 2 recievers leap frogging or all 3 leap frogging using a cors station. (out of the box, i know but it works)
are you "holding" your base in ashech solutions when processing? etc. alot of questions but we will get you fixed up

Good morning Ty.
Right off the bat, I've got you confused. Sorry. I have two receivers, one I use as the base, one I use as the rover.
Ā I set up the base using a tripod, tribrach, Kinimatic bar, Ashtech antenna and one receiver set at 'static' survey mode.
The rover I have set up on a rover pole, Ashtech antenna and the second receiver set to 'stop and go'. The antenna is initialized on the kinimatic bar and then transfered to the rover pole after the 5 min initialization and then I start moving to my points. Ā I set the raw data interval to 1 second and data acquisition to 15 seconds.
Points are recorded by logging for 15 seconds. etc etc.
The data imported into GNSS Solutions usually comes out approx 50% fixed and 50% floating. I don't know if I should be increasing the 15 second data acquisition to more, or if there is something else I'm missing.
Any help is appreciated.
Cheers, Sid
Sid,

How often during your session do you lose "lock" I must say the Promarks "RTK" wasnt the most favorable, but i think i can get you going.

when you lose "lock" are you re init on a known point collected previously?
