Chapter 4 PQ3198 GPS Positioning and Time Correction

Position the GPS antenna so that it has a clear view of the overhead sky, with no obstruc-
tions nearby.
See:
When turning on the PW9005 for the first time, or when the device has not been used for a
certain period of time (about 1 to 2 weeks, with the power turned off the entire time), it may
take some time after connecting the device to the PQ3198 and configuring it for it to
acquire satellites and calculate its position. (Depending on the environment in which the
antenna has been installed, this process may take anywhere from several minutes to sev-
eral dozen minutes (p.16).)
Once the PW9005 has calculated its position, the PQ3198 will begin time correction.
When starting recording with the PQ3198, be sure to verify that the GPS mark (p.14) is blue.

Note that if PQ3198 recording is started while time correction is disabled,
GPS time will not be used to record times and event times on time series
graphs.

The PW9005 is unable to acquire satel-
lites or calculate its position.
*If the GPS mark is red, it is possible that
the PW9005 and PQ3198 have not been
connected properly.(p.7)
