Compact Tracking Mount (CTM)


Compact Tracking Mount (CTM)

The Photo-Sonics Compact Tracking Mount (CTM) provides a high performance TSPI, vibration-free data gathering system in a rugged, portable configuration.  A primary goal was to design a system that could be transported, set up and operated by one individual, while retaining features of the typically larger tracking mounts.  With over 30 years of experience in designing and manufacturing tracking systems, Photo-Sonics has incorporated the same high performance and quality engineering found in the field-proven Cine-Sextant Tracking Mount.

The CTM utilizes three custom, direct-drive torque motors which provide 1500 foot-pounds of torque in the azimuth axis and 750 foot-pounds of torque in the elevation axis. This high level of torque is provided to maintain maximum dynamic tracking accuracy when the CTM
is moved in close to the target and when high acceleration is required. It is also essential for maintaining consistent tracking performance with heavy or unbalanced payloads.
All major structural members including the base casting, azimuth carriage, and instrumentation platforms are cast of high strength aluminum alloy.  The overall dimensions and weight of the CTM allow for air transportation in a C-130 and attachment hardware on the trailer is provided for lifting the system by crane or helicopter. Four motorized jacks, located at the extreme corners of the trailer, provide a wide footprint for a stable tracking base. The CTM is offered in both man-in-the-mount configuration and/or an unmanned remote control console configuration.

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.
