[gpsd-users] Changing the GPS update rate with gpsd

[Deven Hickingbotham]

Is there a way using one of the gpsd tools to set the GPS update rate? 
Can this be done while gpsd is running?

By update rate, I mean once per second, 5 times a seconds, etc.  IOW, I 
want to send a command like $PMTK220,100*2F/r/n.

Details:  Using a Raspberry Pi with an Adafruit Ultimate GPS Hat 
(GlobalTop FGPMMOPA6H chipset).  Under Wheezie (Debian 7.8) and gpsd 
3.6, I was able to use a script to change the update rate of the GPS and 
this rate was retained when restarting gpsd.

Under Jessie (Debian 8.0) and gpsd 3.11-3, while I can still change the 
update rate of the GPS, when restarting gpsd the update rate is reset to 
once per second.

So I'm looking for a way to have the update rate retained when 
restarting gpsd or a way to change the update rate while gpsd is 
running.  If there is a way to do this with Python code, and example 
would be appreciated!
