Data logging

Data logging allows the Teseo-LIV3F receiver to locally save the resolved GNSS position to

the flash in order to be retrieved on demand from the host.

Teseo-LIV3F supports only one datalog at a time.

Datalogging can be enabled, disabled and erased using proprietary NMEA runtime

commands.

Datalogging subsystem supports both:



Circular buffer



Standard buffer

The recorded data is configurable; datalogging supports three types of data logged.

Each type has a different size and different data logged. All the data logged types have:

timestamp, latitude and longitude while other fields depend by the type. See Table 5. for

details.

Teseo-LIV3F can support until 12 hours logging using log-type 1 and fix rate at 1 Hz.

Detailed information is available on Teseo-LIV3F software user manual.
