Relates to data being transmitted from GH-615. Activity is a
history or log of events. Activity data includes time or distance
updates.
Waypoints are sets of coordinates that identify a point in
physical space. For the purposes of terrestrial navigation,
these coordinates usually include longitude and latitude, and
sometimes altitude (particularly for air navigation).
The current moving trace.
The act of determining the course or heading of movement.
A two-dimensional GPS position fix that includes only
horizontal coordinates. It requires a minimum of three visible
satellites.
A three-dimensional GPS position fix that includes horizontal
coordinates, plus elevation. It requires a minimum of four
visible satellites.
GPS signal is weak (GPS is fixing).
Can't find GPS (GPS turned off or broken down).
Navigation Overlay Service. These are two satellite-based
systems that can be used to increase the accuracy of GPS
position fixes.
An IPX7 designation means the GPS case can withstand
accidental immersion in one meter of water for up to 30
