    hi, video was very explanatory and in detail.
    I have a question.
    you said that bearing and distance would be varied by time for base and consequently for rover. does it mean everyday i will start the survey and will find point ‘B’ at different location (as a result of change of bearing and distance from one point to other).if it is so then how will achieve accuracy in ‘mm’?
    I am talking about the RTK.
    Waiting for reply.

      Hi,
      Firstly it was a nice question.
      I had also the same doubt and to check this I have tested it by talking two observation on a same point at alternative day. And I found a very small variation, however the variation was little big in respect of mm as I established Base point with a observation of 5 hr only. In normal min 24 hrs base observation is required before starting survey work.
