Table 4-6. CODE 63 DISPLAYS FOR 3D POSITION
Enter code 63 to display the most recent computed 3D (point) position. The 30
(point) position computation is based on accumulated data from all pass data
c o l l e c t e d.
The 3D (point) position is displayed in a sequence of 15 displays.
Press the enter (E) key to erase one display and view the next. The initial display
shows the following information:
1.
3D (point) position code mnemonic (PT).
2. When this position is blank, the point position was computed using data from
t h e l a s t s a t e l l i t e p a s s . A o n e - l e t t er
pass data was not used. The following
from the last pass.
O - No 20 fix could be computed.

codes signify the reason for not using data
C - Less than e
D - More than 1
ight doppler counts used in 2D computation.
km (0.62 miles) between 2D position and reference position.

E - Maximum elevation angle of satellite less than 15 degrees.
H - Maximum elevation angle greater than 70 degrees immediately after 3D
position was reset.
I - More than six iterations occurred in 2D computation.
R - Only one of two satellite receiver channels was used to calculate 2D position
due to insufficient data on other channel.
