Re: [gpsd-dev] capturing raw logging output for Garmin USB devices

Sorry, no.  We have support for extracting pseudoranges in some of the device 
drivers, but it isn't exported as a JSON report to clients yet.  A major reason
for this is that test hardware that ships the raw data is expensive - lots
of GPS vendors, including SiRF, treat the capability as an extra-cost firmware
option.

Another is that we don't have a way to check that the decoding is correct.
What we'd need for this is test pairs - that is, sentences containing
pseudorange data paired with a decode of it done by known-good software.

If you can supply test pairs we'd love to implement this feature. We've
wanted to for years.
