I believe the gpsd package in Raspbian sets up GSPD to autostart. With the  
default configuration, however, GPSD dies at startup, but systemd is  
"helpfully" listening on its port, ready to pass data on (but GPSD is  
dead). As a result, when you run GPSD from a console, it will find the  
default port already occupied, and cgps with the default port will get a  
connection (systemd init is listening), but no data (init isn't doing  
anything with the port, other than notionally forwarding it to GPSD). If  
systemd has tried to start GSPD, then whether GSPD is currently running or  
not, you can't use the default port to start it from a terminal. You have  
to use the -S option to specify an alternate port, then point cgps at that  
port when you run it.
