(max).
The value 7 represents an accuracy estimate of worse than 256m.
Note: If there is no GNSS fix (see sensor status), the Lat. and Lon. fields contain the last values reported by the
GNSS receiver. If there has never been a GNSS fix acquired, the values may both be 0.
*Note2: little-endian format.
