22.2.4î™–î™–î™–î™–Notes
• To know the allowed combinations of GNSS type for <GNSS_systems> see the corresponding GNSS
receiver documentation.
• If <GNSS_systems> type is not supported by the GNSS receiver, the set command turns on the GNSS
receiver with built-in supported type. The current <GNSS_systems> can be queried by means of the read
command or the +UUGIND URC.
• An error result code is provided in the following cases:
o
<mode>, <aid_mode> or <GNSS_systems> values are out of range
o
<mode> is set to 1 without <aid_mode> value
o Attempt to power off the GNSS when it is already off
o
The
value
of
<aid_mode>
to
be
set
is
equal
to
the
current
GNSS
aiding
mode
and
the
value
of
<GNSS_systems> to be set is equal to the last requested <GNSS_systems>
• The parameter <GNSS_systems> is displayed in the information text response of the read command only
if the connected GNSS receiver supports Multi-GNSS

22.3.1î™–î™–î™–î™–Description
Enables or disables sending of URCs from MT to TE in the case of GNSS aiding operations. The <mode>
parameter controls the processing of URCs specified within this command.
The URC returns the result of an assisted GNSS operation. This information is sent to all the interfaces. The
URC is provided only if one or more aiding modes are enabled (for more details see the +UGPS and +UGAOP
command descriptions).
There can be more than a +UUGIND URC for a single aiding operation: the +UUGIND is reported for each error.
For instance if the local aiding is enabled and there are no space left in the file system after +UGPS=0, there
will be an error for every failure writing on FFS.
The commands +UGAOS=0 and +UGAOS=1 both relate to the GNSS local aiding, so the unsolicited message
will be +UUGIND=1,x in both cases.
Local aiding and AssistNow Autonomous will produce URC both after GNSS power on and before GNSS power
off because some data are transferred from the GNSS receiver to the cellular module.
If the connected GNSS receiver is Multi-GNSS then an additional +UUGIND=0,<GNSS_systems> URC for the
currently activated GNSS systems is displayed.
