The Photo-Sonics
Cine-Sextant Tracking system provides a high performance, TSPI data
gathering system in a rugged, mobile configuration.
The
Cine-Sextant utilizes three custom, direct-drive torque motors: one 1800 foot-pound torque
motor in the azimuth axis and two 550 foot-pound motors providing
1100 foot pounds of torque in the elevation axis. This high level of torque is provided to maintain maximum dynamic tracking accuracy
and performance with heavy or unbalanced
payloads. Four motorized jacks provide a wide footprint for a stable tracking base.
All major structural members including the base casting, azimuth carriage, and
instrumentation platforms are cast of high strength aluminum alloy. The attachment
hardware on the trailer is provided for lifting the system by crane or helicopter.
The Cine-Sextant is offered in both a man-in-the-mount and/or an
unmanned configuration with complete remote control operation. In
the unmanned configuration the customer has the option of
configuring a center platform for mounting additional payload such
as a 34” aperture telescope and sensor suite. |

Mobile and Fixed-Site Cine-Sextant Systems |
The Photo-Sonics
Mobile and Fixed-Site Cine-Sextant tracking systems provide
smooth, high-dynamic performance TSPI tracking of a target anywhere in the
celestial hemisphere that begins 8 degrees below the
horizontal.
The Cine-Sextant serves as a support system mounting of
cameras or any electro-optical devices used in target
tracking and data acquisition. This mount requires only one
man for set-up, alignment and operation. Its four platform
mounting surfaces can carry up to 250 pounds each with no
loss in performance.
The basic design requirements of the tracking mount are the
same in both mobile and fixed installation systems. The
tracking mount consists of a base assembly that contains
three leveling screws, azimuth drive motor, tape cables, and
azimuth carriage assembly. The azimuth carriage carries the
control stick and the operator seat, and also supports the
elevation axis assembly, comprised of the elevation drive
motors and the elevation payload carrying platforms.
Encoders of any desired accuracy up to 23 bits can be
incorporated.
Complete power and control systems are located in the
trailer of the mobile unit; in the fixed site installation,
a separate control console is located adjacent to the mount.
In this configuration, a working platform is erected around
the tracking mount, whereas in the mobile version, this is
naturally provided by the trailer deck.

Control Software — The ARGUS control
software
provides all the functionality the user
would expect of
an advanced TSPI tracking system. It provides a
single interface for the tracking pedestal,
sensors,
auto-tracking, radar, calibration, target simulation
and
diagnostics of the complete tracking system. Control of
the
system is simplified via an intuitive touch screen
GUI. The standard ARGUS application can control up to
10
sensor stations, in addition to radar and lasers,
allowing
a
single-operator complete control of all
aspects of a complex
and highly capable system from
a remote location. It also
provides the control of single
and dual-gate auto trackers
and fixed focal length and
zoom lenses and focus tables.
Automated Star
Calibration are incorporated to yield the
highest TSPI
accuracy of any optical tracking system
manufactured today.

Refurbishment |
|
Photo-Sonics suggests replacing outdated hydraulic elevation
actuators with DC torque motors to provide higher performance.
The original configuration included hydraulic actuators to
drive the elevation axis. These elevation actuators
required a host of support equipment, including servo
valves, rotary joints, hydraulic plumbing and hoses, crank
assembly as well as several units on the trailer assembly
If you do not
currently own an old style Cine-Sextant, please let us know
and we will provide a unit for refurbishment.
The conversion will effect five major subsystems of the
Cine-Sextant:
● Replaces the hydraulic elevation actuators with
direct-drive DC torque motors.
● Replaces the electronic drawer and power amplifier with an
all new electronic control and pulse-width-modulated
power amplifier integrated into a single package.
● Replaces the crank and single power tracking scope with a
dual power sighting scope with lighted reticule and open
acquisition aid with lighted lines.
● Replaces old style elevation tachometer with new style,
making it a more reliable system.
The upgrade of the Cine-Sextant will provide the following
benefits:
● Higher performance and bandwidth resulting from new style
pulse-width modulated electronics.
● Dumping capabilities to determine systematic accuracies.
● Higher reliability with the removal of the hydraulics.
● No non-linearity's associated with the hydraulic system.
● No elevation stiction inherent with elevation actuators.
● No hydraulic contamination.
● No leakage associated with the hydraulic equipment.
● Lower maintenance costs. |
