GPSD reporting wrong Longitude was created by Bruce Morrell

GPSD seems to be reporting the wrong longitude 256 on all three piers that I operate. Any ideas???... Bruce

It's not wrong, this is how INDI represents longitudes.

I believe the values it reports are all positive values, as if you measured your longitude east of Greenwich. For those of us located in North America, west of Greenwich, the values mean the same thing, e.g. -104 W is the same as 256 E. or =360-104

This explanation makes sense of course assuming your longitude is 104º W :)

Ok I get that now, what through me is, I believe my system had been reporting negative numbers before. Like I am -96 long being west of the meridian, Thanks for the responses,,,, Bruce

Well if you're at -96, ... then the value of 256 looks suspiciously like the max value of an 8 bit number rather than your longitude measured east of the prime meridian.
