That page shows some failure to understand what is going on.

"I have played with a Python script for this, but the snag is that
you need to wait for the gpsd to emit a message with the required
information.  I therefore also tried writing my own two programs to
retrieve the information directly from gpsd,

gpsd emits the SKY JSON whenever it receives skyview data.  Going
'directly' to gpsd does not change this.  If the client wants more
frequent SKY JSON, then the GPS must be set to output skyview data
more often.

Gary,

Thanks for your notes.

All I need is a value every 5 minutes (for MRTG) so the default rate of one 
per second appears to be quite adequate.  As far as I know, my software 
doesn't use JSON at all, just gpsd API calls.

Cheers,
David
