🔢 Actually resolve integers

[sammmlow]

Current LEOGPS basically performs pseudorange double differencing. Should eventually move towards carrier double differencing with IAR.

Hi, can I understand what this issue is about? Does the current LEOGPS resolve for N_float?

[sammmlow]

Currently LEOGPS estimates float ambiguities only (no fixing) and does not exploit carrier phase information to do it. It only does pseudorange double differencing. If carrier phase is exploited we can bring the nav accuracy down to cm or mm level. Likely will be a very big change to ambest.py to do batch IAR instead of sequential epoch-by-epoch FAR as it is trying to do now; will take a large time commitment from me but leaving it open as an issue so I can get to it when I have the bandwidth to do so
