3-12. Initialization, Hot Start - Continued
(3) Once alignment is completed IPADS can begin survey operations.
(4) If an adjustment was not conducted prior to performing a hot start, survey operations
may continue as long as the vehicle was not moved while shutdown (i.e. hot start
succeeds or operator confirms position by pressing F8 in the UPDATE page).
e.
Post operations.
Do not move the vehicle or readjust cargo: Excessive movement will prevent IPADS
from being able to conduct a hot start
f.
IPADS position initialization.
IPADS requires position initialization if indicated by a flashing "F3-UPDT" on the
function key line. IPADS does not need to be initialized at a SCP; however, initialization
site horizontal coordinates must be accurate within 100 meters and altitude within 10
meters.
(1) When initialized with approximate coordinates, position must be updated at a SCP
after alignment is finished and before starting the survey.
(2) Use vehicle plumb bob reference for initializing IPADS. If initializing IPADS at a
SCP where survey marker is offset from the vehicle, use approximate initial
coordinates. Theodolite can be set up over marker while IPADS is aligning and a
theodolite position update performed when alignment is finished.
(3) Horizontal position and altitude are required for position initialization.
(4) Set ellipsoid, datum, and position coordinate type before entering initial position.
(5) The procedure to enter initial positions is similar for UTM and geodetic (latitude and
longitude) coordinates
a.
Perform the following steps to initialize position and altitude by selecting a point from the IPADS database,
entering coordinates for a new point, or searching for a point name:
(1) Verify position format is set correctly, paragraph 3-11e(3)
(2) From MENU, press F3. UPDATE: page is displayed with PRESS F1 FOR PLUMB BOB; F2 FOR
THEODOLITE on information line and F1-UPDT-PB, F2-UPDT- , and F9-EXIT on function key
line.
(3) Press F1. UPDATE: PLUMB BOB: UTM or geodetic page is displayed with cursor box on PNT
NAME: field. Function key line shows F2-NEW, F3-SEL PT, and F9-EXIT.
b.
Perform the following steps to select an existing point from database list:
CAUTION
If F5 (DEL ALL) is pressed, IPADS prompts PRESS Y TO DELETE
DISPLAYED POINTS; OTHER KEY TO CANCEL. Pressing Y permanently
deletes all points in displayed list.
(1) Press F3. POINT LIST page is displayed with function key lines F2-NEW, F3-SEL PT., F4-FILTER,
F5-DEL ALL, and F9-EXIT.
