Hello everyone. Im using ANN-MB-00 as my base station antenna for almost two years now and its working great but there are two issues i noticed over the two years that ive been using it.
One issue is sometimes i get random drop in quality when im in the field or on the road, quality goes from RTK to Float and even DGPS sometimes but it gets back to RTK in a couple of seconds. It happens very fast and its not really a problem but it bothers me. Also worth mentioning is that when this happens there are no trees and other things that can interfere with my tractors antenna.
Second issue is that when for example going west to east in one pass is precise, every time i go that same pass west to east is good but when going that same pass east to west it looks like the tractor is roughtly 5cm moved to one side even though AOG says its on the line. I hope this makes sense.
Note: base station antenna is located on top of a steel shed with clear view of the sky, no trees, no power lines and its mounted on a steel plate 10cmx10cm. Using ethernet connection to router. Running ESPRTK sending correction to Emlid Caster. Base station position is from a survey in that ran for four days, two years ago roughtly.
