5.2.2.5
Initiating a GPS Position Information Transmission (Push, Immediately)
By means of softkey 'Immediate PUSH' the operator can immediately transmit (push) its cur-
rent GPS positioning information (see sect. 5.2.2.1 Display of the GPS Position) to other par-
ticipants operating in the same network.
Softkey
If a GPS participant has currently only limited or no GPS satellite visibility, it will push empty
GPS positioning information to the network. Also, immediate push actions can be executed
even if the GPS time signal (required for scheduling) has never been received.
Immediate GPS data are transmitted unscheduled (see sect. 5.2.1.2 Types of GPS Trans-
mission). Hence, there is some potential that any unscheduled transmission conflicts on-air
with other (scheduled or unscheduled) GPS transmissions and hence cannot be received by
other GPS participants.
On the other hand, an immediate transmission is executed without any scheduling delay.
Therefore immediate push transmissions should be used in situations when a delay in trans-
mitting the GPS push data cannot be accepted or in case the GPS time signal (required for
scheduling) has never been received yet.
The reception of the immediately pushed GPS position information by other GPS participants
is described in sect. 5.2.2.10 List of Received GPS Position Information.
