Question about
undermutt
Posts: 22
I have a PMB-688. It is currently feeding a routine that reads date, time, lat and long and uses the information to calculate local sidereal time and load it to a clock.
I have this code snippet...
GPS : "GPS_Str_NMEA_Lite"
GPS.StartCOGs(_RX_FM_GPS,_TX_TO_GPS,_GPS_SER_MODE,_GPS_SER_BAUD)
repeat
dbg.home
dbgMWD(gps.Str_Course_Over_Ground, false, false)
time.pause(400)
dbgMWD puts a string or two to the serial terminal
My question is, should I expect the reading to change as I rotate the gps?
When I attempt to do this I get erratic results.
Granted, I'm sitting at my nice warm desk doing this because its 15 degrees outside, but my phone is sitting right next to the gps and it is using 15+ satellites.
When it warms up a bit tomorrow I'll try again outside and see what happens.
In the mean time, If the answer to the question is yes then a few hints pointing me in the right direction towards the random results would be helpful. However, if the answer is no, then a brief explanation as to why or pointers to info that will help me along my way.
Thanks,
Rick.
