My employers are looking into a partnership with a company that provides RTK base stations (they specialize in Topcon equipment) and are planning to replace our old total station with a Topcon HiPer SR receiver, controller as yet undecided. I'm being asked to research base stations/GNSS receivers but I learned nearly nothing about base stations besides that they are useful things during my GIS training and my Google skills have been failing me. I work in a N-S running valley in the Canadian Rockies that's full of gentle hills and am mostly looking to collect accurate data points from urban infrastructure (utility networks, roads, etc), and my questions are:
- Will an RTK base station still provide accurate (within a few cm) data collection if the area in question is not very flat?
- Do certain brands of RTK base stations perform better than others or are they all about on par?
- Are there any features I should specifically be looking for/avoiding in a base station set-up?
- Are there other options for high-accuracy data collection that would work equally well/better than a base station/GNSS receiver in my situation?
(I'm new here so I apologize if this question is no good or needs work)
