Vertical Error with Conventional Total Station
I have been using trimble robotics for the past 10 years where you can close out traverses with very little error. I recently started my own buisness and could not afford the 30k price tag that comes with robots these days so I purchased a Nikon N 5″ conventional gun which is the new version of the NPL 322. Horizontal error is pretty small but I have noticed that I usually have a decent amount of vertical error after setting a traverse point and setting up on it/backsighting the point that I set it from. Usually 5 hundredths at 300′ and sometimes 8 hundredths at around 600′. Ive used conventional total stations early in my career but do not remember how good the vertical was. Is this common or is there something going on with my gun? My rod height and instrument height are always correct and I am running survey pro. Maybe there is some kind of collumation that could be done? Thanks for your input.
