NTRIP RTCM3 message parsing fails with KeyError in `pyrtcm` with certain caster streams #10

Closed semudev2 closed 2 years ago

NTRIP RTCM3 message parsing fails with KeyError in pyrtcm with certain caster streams:

e.g. ntrip.data.gnss.ga.gov.au/CAS100ATA0

Seems to be a problem in the cell2rpn routine in rtcmhelpers.py which maps satellite and signal IDs to MSM message group attributes- possibly incorrect index range?

PyGPSClient version 1.3.7 pyrtcm version 0.2.8
