I've corrected a program which I understand may have been referred to in the GPS distribution. Previously I was only looping on satellites, but only up to the number used. I should have been looking at all the visible satellites and measuring those which were used. I recall Gary noting that my SNR values were lower than expected. This change resolves that issue.

      for(i=0;i<=used;i++) {

      for(i=0;i<visible;i++) {

The update has been added to my Web page at:

I'm unsure what else I may need to do.

I tested on a number of Raspberry Pi versions, but some other updates outside gpsd mean that gcc can't find lgps, and running install libgps-dev didn't resolve the error, and on another the installer couldn't find libgps-dev as the OS was too different. I've not chased these issues any further.
