Backward Bearing & Distance,
height excluded
Point A - GPS point towards which
bearing
α is measured.
Bearing - Bearing Angle to Point A
in units configured.
Distance - Horizontal distance from
the Hidden Point to Point A in units
configured.
Use ABORT (F1) to abort the
procedure. When Point A is high-
lighted, use NEWOC (F5) to occupy
that point.
Go to the Hidden Point. When Bear-
ing is highlighted, the BRNG (F6) key
is available. This function may be
used if you do not know or have no
device for determining the bearing.
Select a point that lies on the line HA
(see diagram). Occupy the point and
press BRNG (F6).
Input a Point Id and the Direction
(Toward or Away from Point A).
Then press OCUPY (F1) and STOP
(F1), STORE (F1) according to the
Occupation Settings. The Bearing
towards Point A will be calculated
using the auxiliary point and Point A.
A - GPS point towards which
bearing
α
is measured
B -Measured Distance from H to A
C -Auxiliary Point (optional)
H -Hidden point
α αα αα
- Measured Bearing from H to A
