[21:17] <jcoxon> is it wrong to put a pnp transitor on the ground pin of a gps?
[21:17] <jcoxon> to turn it on and off?
[21:19] <Laurenceb_> on the gnd pin?
[21:20] <Laurenceb_> you mean power surely?
[21:20] <jcoxon> thats the thing
[21:20] <jcoxon> i've seen example circuits where the transistor is 'connecting' the load to ground
[21:25] <Randomskk> basically you ideally want NPN between load and ground
[21:25] <Randomskk> and PNP between +V and load
[21:26] <Randomskk> but uhm, it may work fine the other way
[21:26] <Randomskk> and if you test it and it works, fine
[21:31] <jcoxon> it seems to work
[21:43] <jcoxon> its a p2n2222ag and it seems to be working okay :-)
[21:44] <fsphil> what's the voltage drop across the transistor?
[21:44] <jcoxon> whats teh best way of measuring that?
[21:45] <fsphil> a multimeter on the emitter and collector when it's on I think
[21:45] <jcoxon> will do that in a bit
[21:51] <jcoxon> hehe http://www.youtube.com/watch?v=OkQkeKbTP_w
[22:01] <jcoxon> okay i've got my GPS powering on and off as required
[22:02] <jcoxon> is it worth me once i get a lock letting it settle down or can i take the first proper lock to be correct
[22:02] <Laurenceb_> i just use the vreg EN pin
[22:02] <Laurenceb_> as that has softstart as well
[22:03] <fsphil> I've never seen the first fixes be any more inaccurate as the others
[22:03] <jcoxon> thats what i suspected
[22:04] <Laurenceb_> i have, but not vastly
[22:05] <Laurenceb_> is this an fsa03?
[22:05] <jcoxon> gpsbee
[22:05] <jcoxon> so ublox 5
[22:05] <SpeedEvil> jcoxon: On most GPSs I've seen they will be some meters more inaccurate on first position
[22:05] <SpeedEvil> ~10-20
[22:06] <SpeedEvil> they settle down lots after 10-30s
[22:06] <Laurenceb_> yeah - its the way the filter works
[22:06] <Laurenceb_> ublox5 has a shutdown option
[22:07] <jcoxon> Laurenceb_ yeah i've used that before
[22:07] <Laurenceb_> but aiui its not going to get you down to tiny current draw
[22:07] <jcoxon> goes to about 10mA
[22:07] <Laurenceb_> ah thats hardly amazing
[22:07] <jcoxon> but this will be off for long periods of time
[22:07] <SpeedEvil> If it's keeping all of the filter state, and not looking at the satellites - you're still going to get a large spike in inaccuracy as you slew massively
[22:07] <jcoxon> so i think just switching it off is better
[22:07] <SpeedEvil> It can't both determine the position and velocity well after large jumps.
[22:11] <Laurenceb_> keeping the backup bat supply will help a lot
