Roles of Radios Supporting GPS Reporting
The role of a radio participating in GPS (Global Positioning System) reporting can be pre-
selected via R&S RNMS3000 or dynamically selected via MMI (Man-Machine Interface) /
REMOTE interfaces.
Provider
A GPS provider is a radio providing GPS positioning data to other GPS participants. It does
so by
•
manually or automatically pushing its current GPS position information onto the network,
•
responding to GPS control / configuration requests being received over the air from an-
other, dedicated radio GPS participant called GPS controller.
Controller
A GPS controller is a dedicated radio GPS participant being able to
•
request (pull) GPS positioning information from other participants and
•
control / configure the automatic GPS transmission of other participants.
The controller commands other GPS participants over the air by using the radio dedicated
GPS control commands. The transmission of these commands can be initiated manually via
the MMI or via the radio REMOTE interface by an external application.
There can be one or multiple GPS controllers in a waveform specific network. It is an orga-
nizational challenge to ensure that control requests of multiple controllers do not conflict.
Controller Acting as Provider
In order to ensure that the GPS positioning information of a controller radio remains “hidden”,
by default a controller does not respond to pull and control / configuration messages received
from another controller. Also, it does by default not take part in automatic GPS reporting (see
sect. 5.2.1.2 Types of GPS Transmission). If a controller shall exceptionally support the
above actions, the mode "Controller Reports Position (CRP)", needs to be enabled. The CRP
state (enabled or disabled) can be pre-selected via R&S RNMS3000 or dynamically enabled
/ disabled via the MMI / REMOTE interfaces. When CRP is enabled, a controller also auto-
matically transmits its own GPS positioning information when pulling or configuring other
GPS participants.
