OPERATOR'S MANUAL
FOR Q-BAY PACKAGE TYPE 1
1. Q-BAY PACKAGE TYPE 1, SYSTEM DESCRIPTION
Q-bay Package Type 1 is an aerial panoramic camera system with the
mission of obtaining photographs of the earth from an airborne vehicle.
The camera system photographs the-earth transverse to the vehicle
line of flight. Two identical cameras are employed to accomplish the photo-
graphy -- a forward camera and an aft camera.
Photographic coverage of the camera system is represented in Fig-
ure 1. The forward camera scans the earth from 67 degrees to the left of nadir
to 21 degrees to the right of nadir. The aft camera scans the earth from 21
degrees to the left of nadir to 67 degrees to the right of nadir. Each mission
can provide 2500 nautical miles of flight line coverage on 1980 frames and 60
miles (or 134 degrees) total transverse coverage. The scan overlap provides
full stereo viewing of mission results for all points on each frame format.
See Figure 2,
The Q-bay Package Type 1 consists of two major assemblies -- a
stable platform and a supporting frame assembly. See Figures 3 and 4. The
stable platform is an aircraft type structure that contains both camera sys-
tems and associated subsystems, and the stabilization system. The stabilized

platform is gimbal supported at its center of gravity through a gimbal support
rod that is fixed to the frame assembly. The frame assembly is installed dir-
rectly in the Q-bay at four isolation shock mounts.
The platform is normally in either one of two conditions: caged
.or-uncaged.--In?the?caged--condition, the platform is-locked to the frame and
therefore fixed with respect to the vehicle (except for 3/8-inch isolator free- ?
dom). In the uncaged condition, the platform is freely suspended from the gim-
bal support rod and is allowed to stabilize with respect to rate and verticality.

the condition of the platform.
2. Q-BAY PACKAGE TYPE I CONTROL PANEL
The control panel for Q-bay Package Type 1 is shown in Figure 5.
The panel is located on the left side, rear portion of the vehicle cockpit con-
sole, and occupies an area approximately 6 inches by 3 inches. See Figure 6.
The Large Status selector switch, Figure 5, controls the operation
of the package. The smaller V/H option selector switch controls the V/H in-
put for camera functions. The TIMER-OFF toggle switch controls the data re-
cording on the film and the automatic exposure control programmer. Three in-
dicators are: CAGED (RED); STBY 2 (AMBER); and OPR (GREEN). Control panel
switches and indicators are listed in Table I.
Q-bay Package Type 1 failure is indicated by a Q-BAY EQUIP OUT
indicator (RED) located on the warning panel center console. This will be
discussed later.

3. STATUS SWITCH. The status switch is a 4-position selector switch. Posi-
tions and functions are:
a. STBY 1 position - The STBY 1 position energizes the forward
and aft camera scanner drives, the gyro spin motors, and all electronic sub-
systems for system warmup.
(1) The scanner cubes are exposed to heat
via the vehicle windows; as a result,
the scanner optical elements may tend to
expand. Thermal expansion of the optical
elements is evenly maintained, and possi-
ble deformation of the optical surface is
prevented by having the scanner cubes ro-
tate at a'constant idle velocity prior
to a mission-run.
(2) The STBY 1 position also energizes the
Q-bay Package data recording mechanism
stepping motors. .The stepping motors'
must be synchronized with the INS inputs
to reflect correct latitude, longitude,
and ground speed. The INS (Inertial
Navigation System) and the data recording
stepping motors are synchronized prior to
take-off. At that time the data record-
ing mechanism readouts follow INS signals.
Data information, however, is not recorded
on the film until the TIMER switch is
placed to the TIMER position.
(3) The STBY 1 position of the STATUS switch
also places critical system electronic
packages in a warmup condition. Q-bay
Package Type 1 is a critically aligned
assembly; both mechanically and electron-
ically. Thermal stabilization of all
critical components is achieved for proper
operation of the overall system by placing
the STATUS switch in the STBY 1 mode prior
to take off. STBY 1 also energizes the
gyro spin motors to allow time for them to
reach proper rpm.
b. STBY 2 position - The STBY 2 position energizes the magnetic
data flight recorder and maintains all of the conditions determined by STBY 1.

The flight recorder tapes critical system functions for post flight evaluation
of overall system operation. The STB? 2 position thus maintains the magnetic
data flight recorder in operation during intermittent operation of the Type 1
equipment.
c. OPR position - The OPR (operate) position of the STATUS
switch places the package into the photography mode. When the STATUS switch
is placed in OPR, the following events normally occur:
(1) The system "starts up". The GREEN indicator
lights. Film is transported through each
camera, all phasing and synchronism of com-
ponents occurs, and photography takes place.
Time from initial start-up to normal oper-
ating speed requires approximately 1-1/2
minutes.
(2) The system will uncage if the vehicle atti-
tude is within discrete attitude limits.
The RED caged indicator will not light. - or
(3)
The system will remain caged if the vehicle
attitude is not within discrete attitude
limits. The RED caged indicator will light.
d. OFF position - The OFF position of the STATUS switch shuts
down the entire Q-bay Package Type 1 equipment.
CAUTION
The OFF position is equipped with a special
detent to prevent accidental placement of the
STATUS switch to the OFF position. The STATUS
switch must be simultaneously pushed in and
turned,to place switch from STBY 1 to OFF posi-
tion.
4. V/H OPTION SWITCH. The V/H option switch controls the V/H inputs to the
camera system. Three types of V/H inputs are provided for three different
flight conditions. These are:

a. SENSOR position. The SENSOR position is the normal position
11 for the V/H OPTION switch. This position is selected during normal flight con-
ditions and cloudless weather conditions.

b. CL (Clouds) position. The CL (Clouds) position-iS?Selected)
during normal flight conditions where partial cloud cover intermittently ob-
structs the ground scene.
C. EMER (emergency) position. The EMER (emergency) position
is selected during abnormal flight conditions when one vehicle engine is out
and an emergency vehicle altitude is necessary.
5. TIMER SWITCH. The timer toggle switch controls the data flasher and the
camera exposure programmer. The main purpose of the timer is to permit the
operator to control the operation of the exposure programmer during a mission,
and thus assure that camera operation during preflight checks will not in-
advertently cause the data chamber to record the operational base coordinates
on the film.
NOTE
II,
., Data flasher can operate only when
the TIMER switch is in the TIMER
:I position and the STATUS switch is
in the OPR position. Exposure
Programmer will operate when the
TIMER switch is in the TIMER post-
7.]
tion and the STATUS switch is in STBY 1,
STBY 21 or OPERATE position.

6? Q-BAY PACKAGE TYPE 1 AND VEHICLE RELATIONSHIPS
Q-bay Package Type 1 is dynamically influenced by the vehicle under
normal conditions in two ways:
a. Power Inputs
b. Vehicle Attitude
7. POWER. Q-bay Package Type 1 normally derives its power from vehicle in-
verter number 2. Power requirements and input configurations are such that
operation of the package should not be affected by the loss of one engine or
by switching inverters.
8. ATTITUDE. 'Photographic performa:nce of Q-bay Package Type 1 depends upon
platform attitude. Platform attitude should be level: in pitch and roll and
parallel in azimuth with the vehicle line of flight.
The Q-bay Package Type 1 is installed in the vehicle such that in
the caged condition the platform is level in pitch and roll when the vehicle
is at a nominal cruise .attitude of +7 degrees in pitch and 0 degree in roll.
See Figure 7.
Q-bay Package Type I will uncage in the operate mode only when the
platform is coarse level -- within ?2 degrees on true vertical. The vehicle
must be within ?2 degrees in pitch and roll of its nominal cruise attitude as
shown in Figure 8.
In the uncaged condition, the Q-bay Package will stabilize with
respect to rate and verticality and will automatically align itself with

The Q-bay Package frame physically prevents the stabilized platform from ex-
ceeding the above limits. When any limit has been reached, a corresponding
clearance switch will close and cage the platform.
In the caged condition, the Q-bay Package is fixed with respect
to the vehicle and is level in pitch and roll only when the vehicle attitude
is:
Pitch +7?
Roll 0?
Yaw
During a normal mission-run, the Q-bay Package is expected to un-
cage and cage possibly more than once due to vehicle attitude perturbations
that exceed the platform caging limits. Uncaging is accomplished by a com-
pressed helium supply of limited quantity. When the supply is exhausted, the
platform will not uncage.
It is possible for the platform to experience at lease 25 uncaging
and caging cycles during one mission. Should the number of caging cycles ex-
ceed 25 at any time during the mission, then the possibility exists that the
platform will remain caged for the remainder of the mission.

9. Q-BAY PACKAGE TYPE 1 OPERATION
Q-Bay Package Type 1 does not operate continuously throughout the
entire mission. The package may be operated continuously for a portion of the
mission, or it may be operated intermittently for an extended portion of the
mission. The flight plan will normally indicate the exact operating procedure.
--------The-package-will _operate properly and should be operated when re-
quired either in a caged condition or an uncaged condition. Best photographic
performance, however, can be expected in the uncaged, self-stabilized mode.
When the package is being operated in the caged condition, vehicle attitude
rates directly affect the photographic performance. Vehicle flight' should be
keptas smooth as possible and changes in vehicle attitude should be accomp-
lished as smoothly as possible. This will minimize photographic degradation.
10. TYPICAL MISSION PROFILES OF Q-BAY PACKAGE TYPE 1. Two typical Q-Bay
Package Type 1 mission profiles are shown in Figure 9. Mission 1 shows con-
tinuous operation of the package for a segment of the entire mission. Mission
2 shows intermittent operation of the package for arbitrary portions of the
mission. In practice, the package will always be placed in the standby 1 mode
at. sometime during the final pre-flight check. The package will always start
the mission in the standby I mode. Specific flight instructions will state
the exact sequence of operation of the status switch for the standby 2 and
operate modes, as shown in Figure 10.
11. Q-BAY PACKAGE TYPE 1 FAILURE. The Q-BAY EQUIP OUT indicator (RED) on
the warning panel will light in the event of the Q-bay Package Type 1 failure.
The Q-BAY EQUIP OUT indication on the warning panel can occur only when the

status switch is in the OPR position. When a Q-BAY EQUIP OUT indication occurs,
the package will automatically switch from the operate mode to the standby 2
mode; the green OPR indicator will go out and the amber STBY 2 will light.
12. FAILURE PROCEDURE. Should the Q-bay Package fail during normal operation,
the following procedure is recommended:
a, Place the STATUS switch from the OPR position to the STBY 2
positibn. The Q-BAY EQUIP OUT light on the warning panel will go out. On the
control panel, the amber STBY 2 light will continue to light.
b. Wait 15 seconds.
c. Place STATUS switch to OPR position. One of three possible
indications will occur:
(1) If the Q-BAY EQUIP OUT light lights immed-
iately, place the STATUS switch to the OFF
position.
(2) If the Q-BAY EQUIP OUT light does not light
immediately, but does light after a notice-
able time (approximately 3 to 30 seconds)
return the STATUS switch to the STBY 2 posi-
tion and wait 15 seconds. Then place the
STATUS switch to the OPR position and ob-
serve the Q-BAY EQUIP OUT indicator. If
the Q-BAY EQUIP OUT indicator lights, then
the STATUS switch should be placed to the
OFF position.

(3) If the Q-BAY EQUIP OUT light does not light
within 30 seconds, then the package can be
, considered operational.
13. CONTROL PANEL INDICATORS, PRE-FLIGHT CHECK. All three control panel in-
dicators are of the press-to-test type. All three indicators should be checked
during the pre-flight checkout.
14. CONTROL PANEL EMERGENCY IN-FLIGHT CHECKOUT. Any indicator on the control
panel that is suspected of malfunction during system operation should be pressed-
to-test. If indicator fails to light when pressed, lamps should be changed if
possible.
15. MISSION OBJECTIVES
Ideally, a mission-run will be flown in a great circle route; the
Q-bay Package will operate in an uncaged condition all of the way; the mission
flight path will be exactly as expected; and the photographic results will in-
clude the area of earth desired.
However, circumstances may be during a mission-run that the flight
path is not as expected, or the Q-bay Package has been operating caged most of
the way.
Caged operation requires the utmost attention. Vehicle attitude
rates must be kept low -- the vehicle must be flown as smoothly as possible
to minimize photographic degradation. If flight path correction is necessary
during a mission run, again, vehicle attitude rates should be minimized during
flight path correction,

16. PHOTOGRAPHY WITH AID OF PERISCOPE WIDE FIELD
System operation, in most cases, will be programmed according to
,time and earth coordinates. However, circumstances could be that the operator
is responsible for determining photographic coverage through use of the peri-
scope.
If an object to be photographed appears on the periscope wide
field at a time when the Q-bay Package is in the STBY 2 mode, the package must
be placed into the OPERATE mode within 20 seconds after the object's first
appearance on the periscope wide field. If the STATUS switch is not placed
to the OPR position within the object's first 20 seconds of visibility on the
periscope, then the object will probably not be within the photographic field
of view during the time of photography.
17. MISSION RESULTS
Q-bay Package Type 1 provides matched sets of panoramic photographs
in the format shown in Figure 11. Paired photographs, one forward scan and the
corresponding aft scan, appear with the associated data information recorded in
? an area between them. Approximately 990 such paired photographs with recorded
data can be expected from a full film supply of 5000 feet. Film width is 6.6
inches. Individual frame dimensions are 6.4 inches by 27.8 inches.
18. DATA RECORDING
Vehicle ground speed, latitude, longitude, Greenwich Mean Time,
and the mission flight number are recorded for each frame. See Figure 12. A
CAGED Status indication is also provided, indicating whether the Q-bay Package
was caged or uncaged for any particular frame.
