RTK Point Movement
So I was taking RTK shots for some corners and MH. I am taking RTK readings with duration of 1-2 minutes at 1 second intervals. I am just using a rod with bubble for level. Since I am a strong coffee drinker, I can't seem to hold the rod steady. I can see it moving as I try to place the bubble in the center of the levelling vial. But after processing the RTK shots, I see that the deviation of repeated points are in the <0.01m.
Anyone care to give their take on this?
Correct me if I am wrong, but it doesn’t sound like you are using a bipod to hold your rod on the point. For critical shots such as the ones you are describing I always use a bipod to hold my rod steady. I also make two observations on corners and control points, 3- minutes each with the rod rotated 180° in between shots. Also, take care when shooting MH’s with GNSS. I shoot them with the robot or run levels through them if I need vertical.
I use the bipod even with the robot, partly because it's usually windy, partly cause like you I'm not the most steady sometimes and I'm just OCD and want to he sure everything I set is dead on.
Under a centimeter sounds good enough to me but I can not relate to trying to hold a rod for two minutes without a bi-pod or better.
Some corners and a manhole can be very different things depending on which corners and manhole.
Skip the coffee!;)
