Re: [Paparazzi-devel] UBX vs NMEA Protocol Inquiry

[Roman Krashanitsa]

Chris, you still sort of have to match the binary frames to the message types but you dont have to convert textual representation of numbers into binary form. Some may argue, but I think this is not the main reason why NMEA is not good compared to proprietary ublox binary protocol. NMEA is just a poor standard, it is not robust and the minimum spanning set of commands is too small. I think wiki will do a better job than me explaining this.

All,

I was wondering if someone had a technical explanation as to why the
UBX protocol is faster than NMEA parsing. I know in the past people
have said NMEA sucks and binary protocol's are faster, but I just want
to make sure I understand the technical reason. I know parsing ASCII
strings requires more CPU cycles, but don't you still have to parse
the UBX output as well?

Best,
Chris
