Hello,
My understanding from the sometimes poorly translated Geochron pdf manual is that the following settings should provide me with a log containing three lines of text at one second intervals.
Mode = 1
Log What = RMC;GGA;GSA
Time Between Logs = 00:00:01
Holdoff = 0
WAAS = 0
Instead I get the three lines somewhere between 5-7 seconds apart. After a lot of trials it seems that the following will give me logs of between 1-2 seconds apart.
Mode = 1
Log What = RMC;GGA;GSA
Time Between Logs = 00:00:00
Holdoff = 1
WAAS = 0
What bothers me is that this doesn't correspond at all to what I would expect after reading through the manual. I had, perhaps erroneously, assumed that the time between logs is a setting for the logging interval, and that the hold off was a setting to discard a certain number of position estimations since initial fix information is usually sketchy. What I also do not understand is why the logger can't actually log positions every second (not 1 or 2 seconds).
We have 110 of these loggers that we're using with accelerometers for a study and I've found this to be the case in 6 of them so far.
Any one else had any issues with the GLOGCON settings or can someone explain this behaviour (and possibly how to rectify it)?
Thanks,
Daniel
