Miscellaneous
Specifies the general signal and measurement settings.
●
Ignore time after 3D fix : the time when the coordinates calculated by receivers
are ignored in the test case for some time after the first 3D fix is attained. Some
receivers make a fix far away the true location and converge to that point after cou-
ple of seconds. This setting can bias the error statistics and can be increased for
more stability of the results.
●
Timeout acquisition mode : maximum time duration after that the IVS has to
acquire satellite signals
●
GNSS signal logging : If enabled, the results with NMEA sentence are stored in
log file in the instrument directory
/hdd/Gnss_Gen/Log
.
●
SMx/IVS configuration :
– "Parallel": the configurations of the instrument and IVS are started in parallel
– "SMx first": the instrument is configured first, afterwards the IVS is configured
●
GNSS signal logging rate : sets the rate for GNSS signal logging at
R&S CMWrun.
●
Tolerate position fix lost, maximum tolerance time : allows the 3D fix to be lost
and sets its maximum time duration
●
Timeout tracking mode : maximum total time duration for the tracking sensitivity
search iterations
●
NMEA format compliance : if enabled, the strict format compliance of the DUTs
messages with NMEA standard is required to pass the test
●
Select NMEA version :
– NMEA version 4.10 uses system ID to distinguish between GPS and Galileo
satellites
– NMEA 4.00 and older: No specified Galileo support by NMEA specification.
Galileo ID offset is necessary to distinguish GPS and Galileo.
●
Galileo SVID offset : offset useful to distinguish between GPS and Galileo satel-
lites in NMEA versions < 4.10
Set to Default
Resets all settings in the dialog to the values required by the test specification.
