L26-DR GNSS - $PSTMDRMMFB command (Dead reckoning)

[jg_spitfire]

Hi, what is the function of this command?, the L26-DR GNSS Protocol Specification says “Input map match data�? but I don’t know when could be useful

Thanks

To establish the speed/location into the DR/IMU at some known starting point. Could be stationary if you want to clear sensor drift.

For example outside an ambulance barn, exiting a parking garage, or a pit box with known location.

MMFB stands for Map Matching FeedBack.

It can be used when the platform take data from a Map provider (i.e.: TomTom Map or other....) this map-information can be provided to the TeseoIII to improve the accuracy.

And when should I send a validity flag as valid or not valid?

Sorry but this isn't a Quectel customer support.

Sorry, as this is a ST command I thought I could post this question here, thanks
