GPS mistakes.

The top mistake I am seeing, is the combining of geodetic and plane surveying. Think rotational error. One Point Setup. Geodetic north, at the base. (This is a RADIAL line to the north pole) All goes well, until the user MOVES the base. Now, we do ONE POINT SETUP, and once again, we are on a radial line to the north pole, once again. Also, the scale factor has changed a little. Since both setups are set up using the same protocol, the user ASSUMES that they are the same. They are not. Also, if NO POINTS are common, we ALSO have an error relating to the autonomous solution used two times. Think translation error. And, the 3rd one is not understanding scale factors, combined scale factors, and elevation factors. Anyway, I believe it is the user's responsibility to LEARN and UNDERSTAND how his equipment works. No matter the brand, or boards used inside. In our pressure to practice the 3 G's, (GET a job, GET her done, and GET on to the next one), these are often overlooked. Take time to figure out how it works? I ain't got time to figure out how it works! Seems to be a common attitude. I'll help anybody I can, with this. Happy Friday. N
