from its last location).
Vertical Line
The short line which is silk-screened vertically on the LCD panel symbolizing user's heading.
Warm Start
Power-on sequence when a receiver already has valid almanac data, but must download ephemeris
data for each of the satellites used to establish a position fix.
Waypoints
Waypoints are locations saved in user's GPS unit. These are locations user may later want to return
to or review.
