Yep, I get that there is no such thing as an absolute position in space, but surely regional ground based fixed points are relatively stable?
Another naive question, but why do we use satellite systems for local terrestrial tracking? I have been looking at the timing and environmental issues with satellite and the complicated corrections required to improve accuracy, so wouldn’t it be better and more reliable to triangulate from ground based base stations?
Whilst on a road unfamiliar to me, I reported an incident to the emergency services a while back and they had my phone position triangulated to within a metre within seconds simply by triangulation using phone masts and appropriate timings. Is the reason this is not available to Joe Public due to resourcing?
@m_elias, that’s my thinking. It’s what, £250 for a base station (RTK2B kit and pi), so £1,000 gets four. PPP each of these, set them up as mutual RTK stations and…. wouldn’t you effectively have your own CM accurate RTK network?
@Radmuffins, that’s exactly the plan.
