a trusted source. Location reports are accepted only from authorized Individual Short Subscriber
Identities (ISSI) or IPs, depending on the configured transport layer of SDS or Packet Data.
NOTE:
The Current GPS Cycle ends between 6th and 7th April 2019 at midnight Coordinated Universal
Time (UTC). After this date, your service provider must reconfigure the Current GPS Cycle
codeplug value to avoid malfunctions in GPS location reporting.
Ensure that the application receiving location messages uses valid addresses which are set up
on radio as an authorized ISSI range. Otherwise the radio rejects all system position requests.
You can enable or disable the GPS Location Service through the radio interface. If this feature is
disabled, the Location Service Configuration can be programmed to the following parameters:
Receiver
GPS Receiver is disabled. The radio responds to location requests by informing that location
reporting is disabled.
Receiver and Location Protocol
GPS Receiver and Location Protocol are disabled. The radio does not respond to any location
requests.
Once the GPS Location Service is re-enabled, the radio restores its location service.
The radio supports GNSS triggers functions, using LIP or LRRP, to report GNSS positions when the
radio meets a set of criteria. Your service provider can set up the following triggers, together with their
specific parameters:
