Dual Axes Tracker

Pan Tilt Unit

The Dual Axes Tracker is traditionally used with the Pandora Spectrometer System but is adaptable to various remote sensing applications. The tracker employs high-precision motors with absolute mechanical encoders to position the optical sensor accurately.  

The new sun tracking system is equipped with state-of-the-art motors operating in closed loop mode, capable of accurately positioning larger inertia loads. The motor controller allows easy networking and simplified multi-axis control with the RS-485 Communication protocol. The tracker is designed for continuous operation and can handle sudden load fluctuations during high winds.

It can complete a full rotation in the zenith and azimuthal directions with a precision of 0.01 and a rotation speed of up 1200 degrees/second. Programmable current and speed allow the system to handle torques up to 1.48Nm. Both axes are equipped with electromagnetic brakes to protect the system during power loss. 

The tracker is housed in a weatherized aluminum enclosure and can be equipped with an internal heating element for operation in colder environments.

An optional tripod provides a secure base to mount the tracker and is well-suited for most applications; however, custom mounting options can be accommodated.

The Field Deployable housing can be customized for more extreme climates to suit your needs. The 5U Rack Mount configuration fits in a standard 48cm (19”) computer server rack for those situations where the system is housed in a trailer or lab. The Rack Mount is thermally stabilized with easy-to-open access panels for maintenance. Both systems provide the same quality optical performance and remote access capabilities when coupled with the Pandora 1S Head Sensor and Sun Tracker.
