Cine-Sextant Optical Tracking Systems


Cine Sextant

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 aluminium 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 centre platform for mounting additional payload such as a 34” aperture telescope and sensor suite.


Applications include;  Missile Launch, Ordnance Separation, Target Interception, Test Track, Take-Off and Landing.
