Super Radot Tracking Mount


The original RADOT Tracking Systems were developed by Photo-Sonics, Inc. for the United States Army Kwajalein Missile Range (USAKMR) approximately 10 to 15 years ago.  The RADOTs in use are capable of collecting TSI component data to a very high degree of accuracy using a multiple-station solution technique.   

The basic design requirement for the Super Radot includes a base assembly which contains the azimuth drive motor, tape cables, and the azimuth carriage assembly.  The elevation axis is comprised of the elevation drive motors and the payload carrying platforms.  A separate control console is located adjacent to the mount.  The Super Radot provides smooth, vibration-free tracking within the range of  ±540° in azimuth and -10° to +95° in elevation.  The pedestal is enclosed in an Astrodome shelter.  Electrical and electronic facilities required to operate the mount are incorporated into a local console within the Astrodome and a remote console located in a control room which also houses a computer and Tracking Error Detector System (TEDS) that automatically maintains target tracking once a target is acquired.  In addition to TEDS, the system also operates in manual tracking mode, controlled by a stick controller located in the control room and also in computer mode, which uses pedestal position data and external target data to produce a tracking error signal.

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.
