[chbot] Differential GPS

[Charles Manning]

Hi Robin

As the old saying goes.... it depends.

Some solutions are designed for static positioning (ie a person standing
holding a pole still for n seconds while the position converges) and some
are for dynamic positioning (ie your walnut harvester bumping along at a
metre or so per second).

Some GNSS information (eg. velocity/heading) are only reliable at more than
a certain speed - maybe 1 or 2 metres/sec.

A lot will depend on antenna quality and various other factors.

There are heaps of satellites up now, so good multi-constellation receivers
are giving very good results these days.
