Re: [gpsd-users] TPV Output with only GPZDA

[Andrew Yong]

Hi Gary,

This is what I get:
$PGACK,103*40
$PGACK,105*46
$PMTK011,MTKGPS*08
$PMTK010,001*2E
$PMTK010,002*2D
$GPZDA,142736.000,23,07,2016,,*50
$GPZDA,142737.000,23,07,2016,,*51
$GPZDA,142738.000,23,07,2016,,*5E
$GPZDA,142739.000,23,07,2016,,*5F
$GPZDA,142740.000,23,07,2016,,*51
$GPZDA,142741.000,23,07,2016,,*50
$GPZDA,142742.000,23,07,2016,,*53
$GPZDA,142743.000,23,07,2016,,*52
$GPZDA,142744.000,23,07,2016,,*55
$GPZDA,142745.000,23,07,2016,,*54
$GPZDA,142746.000,23,07,2016,,*57

I see, nearly everything I have found online discourages using
refclock 46. I will probably go back to using the NMEA driver or SHM
driver. Thanks.
