GNSS receivers – why precise positioning will not be coming to your phone any time soon

GNSS receivers – why precise positioning will not be coming to your phone any time soon


Igor is the CEO and cofounder of a company that started out making high-precision GNSS receivers in his kitchen and crowd-funded the first batch on Kickstarter. 


But that was over ten years ago so today on the podcast Igor is going to tell us about the innovations that made this possible, give a great explanation of RTK and PPP and explain why we should expect to see high precision positioning on your phone any time soon.
