ZED-F9R-Integration manual
Only the last rising and falling edge detected between two epochs is reported since the
output rate of the UBX-TIM-TM2 message corresponds to the measurement rate configured
with CFG-RATE-MEAS (see Figure 26 below).

3.11 Security
The security concept of ZED-F9R covers the air interface between the receiver and the GNSS
satellites and the integrity of the receiver itself.
There are functions to monitor/detect certain security threats and report it to the host system.
Other functions try to mitigate the threat and allow the receiver to operate normally.
The table below gives an overview about possible threats and which functionality is available to
detect and/or mitigate it.
