Yes, thank you for outlining your solution!
I am not sure that I fully understand the ins and outs of it, but I am curious if this approach would also allow for a seamless and accurate moving between a “real”-GPS (outdoors) and a “fake”-GPS (indoors), essentially fusing the two environments?
What are your thoughts to achieve this?
P.S.: (We had another discussion in a similar vein here, but it has not come to full fruition yet)
