I am driving a car and I would like to get the trajectory of the car with positions at every second.
The positions should not be less accurate than 1.5-2m.
I can not use RTK because in some places I do not have phone signal and will not receive corrections.
Ideally would be not to use base-rover configuration but I am open to any suggestions.
Well, if you don’t have cellular coverage, and the distances are big, PPK might be the only way. The problem is, you will need to move the base as you go from one part of your journey to another. The only solution I can see is using RINEX from a CORS network(or any local analog). That means your whole route must be covered.
