1.10 Data logging
The u-blox NEO-M8P receivers can be used in data logging applications. The data logging feature enables
continuous storage of position, velocity and time information to an onboard SQI flash memory. It can also log
distance from an odometer function. The logged data can be downloaded from the receiver later for further
analysis or for conversion to a mapping tool. For more information see the u-blox 8 / u-blox M8 Receiver
Description Including Protocol Specification [2].
Note that the location information stored is standard precision only
1.11 Host Interface Signature
The host interface signature mechanism provides protection against unauthorized tampering of the message
data sent from the receiver to its host. This increases the robustness of the system against alteration of position
and/or time information sent from the receiver (i.e. UART). Nominated messages are effectively ‘signed’ by the
receiver using a hashing algorithm to generate a signature message for subsequent checking at the host. A
