5.2.2.9 Initiating an Auto Push List Request Transmission (as Controller Feature)
By means of softkey Auto Push List the operator of a controller radio can send an Auto Push
Configuration Request to all or to a single participant using a scheduled transmission (see
sect. 5.2.1.2 Types of GPS Transmission).
Auto Push request (APR) actions (be it request or response) can be executed only after the
GPS time signal (required for scheduling) has been received at least once. This is due to the
fact that APR transmissions are scheduled in order to avoid on-air collisions with other
(scheduled) GPS transmissions.
An APR request can be addressed to all participants (BROADCAST) or to a single partici-
pant. The selection process of the addressed participant(s) is described in
sect. 5.2.1.3 Addressing of GPS Transmissions.
The auto push time interval [in seconds] of the addressed participants is entered by using a
numerical editor. A default interval of 60 seconds is pre-configured but this can be adapted
to operational requirements. Due to the scheduling constraints (see sect. 5.2.1.2 Types of
GPS Transmission), the time interval can only be set as integer multiple of the scheduling
round time. Thus, the value entered will be adjusted automatically to match an integer mul-
tiple of the scheduling round time. Selecting a time interval of zero disables a previously con-
figured (via APR on-air command or R&S RNMS3000 config) auto push time interval.
