Interpolate across GPS gaps

The figures below show:

1) profile times since launch (top) and distance to the closest
good position on either side of a missing position (bottom);

2) time series of longitude and latitude (top two panels) and average
float speed between fixes (third panel)

3) a simple map with interpolated positions as red circles;

4:6) T and S profiles, and TS relation, with time in color.
Profiles for interpolated positions are marked as heavier lines.
A "time line" at the bottom marks interpolated fixes as black +.

The floats were ordered by GPS gap size, with largest contiguous gaps
shon first.




Cycle times (top) and gap distance (botm) lon/lat time series, and float speed map T profiles, interpolated as thick lines S profiles, interpolated as thick lines TS diagram, interpolated as thick lines
Most of the profiles from 3900758 were sent nearly 2.5 years
after the last GPS fix; IR positions from the submission were
too far for interpolation:
