Field:
GPS Modul/GPS accuracy
Description
4..12 satellites / …ns
The GPS signal is received from 4 to 12 satellites,
i.e. the GPS data is very precise. In addition the accu-
racy of the GPS time is displayed.
3 satellites / …ns
The GPS signal is received from 3 satellites,
i.e. the GPS data is just usable. In addition the accu-
racy of the GPS time is displayed
0..2 satellites / …ns
The GPS signal is received from 0 to 2 satellites,
i.e. the GPS data is not usable. In addition the accura-
cy of the GPS time is displayed.
Bad accuracy
The GPS time pulse (time reference) is inaccurate.
This can be for the following reasons:
 Too few visible satellites
 Unsuitable satellite position
 Shortly after the ITC was switched on
Timeout / …ns
Das GPS time pulse is no longer being received (e.g.
due to a thunder storm). Under certain circumstances
it is possible that the S-com card or the GPS antenna
has not been inserted.
Invalid data
The GPS time pulse is (still) not usable (normally 2 to
10 min. after the base station has been switched on).
No access/ 0xFFFFFFFF ns
GPS module is enabled, but access to the COM port
is not possible.
GPS Modul disabled
GPS module is disabled, therefore synchronised mess
age transmission from the Master is not possible. In
the menu "Configuration" under the link "Optional base
station" the field "GPS receiver" is set to "Disabled"
(this field is visible when being configured as Master
ITC or when the ITC is in standby mode).
