✘NTRIP and RTCM

[Gary E. Miller]

Yo All!

Anyone wathcing git head, or issue 175, will notice that I have been
workong on NTRIP.  Still a lot of rough edges, but progrees.

See attached one one plots, all from the same ZED-F9P and antenna.

Plain3600.png      -- no corrections
23Single3600.png   -- RTCM 2.3 corrections (1 mile away)
3Single3600.png    -- RTCM 3 corrections (1 mile away)
MAX3600.png        -- "MAX" synthetic RTCM 3 correction.

All from the Oregon ORGN network.  Many thanks to them for allowing
me cess.

The CEP(50)s:

0.764m   Plain3600.png
1.149m   23Single3600.png
0.719m   3Single3600.png
0,044m   MAX3600.png

Things to note.

a) RTCM 2.3 made the CEP(50) worse!
b) RTCM 3 was barely better than no corrections
c) The synthetic corrections are just WOW.

u-blox just announced a commercial sat based correcton service that will
beam corrections to any paying customer.  TBD if their corrections are
useful, or if normal people can afford them.
