ZED-F9T - Integration Manual
2 System description
2.1 Overview
The ZED-F9T is a multi-band GNSS module offering 5 ns (1-sigma) timing accuracy with
unparalleled low power consumption.
The ZED-F9T incorporates the u-blox F9 multi-band platform in a small surface mount device with
a form factor of 22 x 17 mm.
2.1.1 Differential timing
The u-blox ZED-F9T high accuracy timing receiver takes local timing accuracy to the next level with
its differential timing mode.
In differential timing mode correction data is exchanged with other neighboring ZED-F9T timing
receivers via a communication network. In differential timing mode the ZED-F9T can operate either
as a master reference station, or as a slave station.
When ZED-F9T acts as a master reference timing station, it sends RTCM 3.3 differential corrections
to slave receivers.
When ZED-F9T acts as a slave receiver, it receives differential corrections RTCM 3.3 messages and
aligns its time pulse to the master reference station.
2.2 Architecture
The ZED-F9T module provides all the necessary RF and baseband processing to enable multi-band,
multi-constellation operation. The block diagram below shows the key functionality implemented in
the module.
