multiplied with DOP to calculate positional accuracy
Default: "'bout three meters-ish" :)

getter/setter pair

Sensor ID - in case multiple positioning sensors are being used
getter/setter pair
- seqNumber ↔ int
-
A sequence number, incremented with each Position message to help
detect lost updates if needed
getter/setter pair
- time ↔ int
-
This is usually not sent over the mesh (to save space), but it is sent
from the phone so that the local device can set its time if it is sent over
the mesh (because there are devices on the mesh without GPS or RTC).
