The WiNRADiO WR-ARP-ELAZ-100 rotator/positioner system is a versatile and robust system primarily developed for automated satellite tracking, but it may be useful in many other applications. A complete functional system, combined with the WR-RCU-100 rotator controller, contains the following items:

 WR-ARP-ELAZ-100 Rotator/Positioner
 WR-RCU-100 Rotator Control Unit
 Power supply, USB cable, application software, user's manual

Whatever is fitted onto the rotator is entirely a matter for the user, be it a Yagi, log periodic or a satellite dish antenna, or, on the other hand, a telescope, heliostat or a security camera. The software provides the user with the ability to manually or automatically position the rotator in a specified direction, with an accuracy of ±0.5 degree in each of the vertical and horizontal axes.

The operation of the supplied control software is very simple. Manual positioning of the rotator is achieved by using the four keyboard arrow keys, or by spin control mouse clicks. Automatic positioning is effected by entering the desired bearing or elevation into a numeric edit field.

Development support is available for experienced users who want to write their own software control application. The API to the Rotator Control Unit is via a set of function calls provided through a DLL file. This support is available at no cost in the form of a Software Development Kit.

WR-RCU-100-ATC Automatic Tracking Controller Software Option

The WiNRADiO WR-RCU-100-ATC Automatic Tracking Controller software option provides the following additional features:

 Fully automated real-time satellite tracking
 Fully automated task scheduler
 Flexible task definition system

What makes the system exceptionally powerful is the ease with which this software automatically tracks orbiting satellites in real time. To enable automatic tracking, simply select the satellite(s) of interest from the presented list, add them to the scheduler, and the scheduler will then position the antenna automatically, to follow the selected satellites as they pass.

The integrated world map also shows the specified satellites orbiting the Earth in real time, and the times of the satellite overhead passes are calculated and displayed.

The user can also program tasks for the scheduler by specifying the action to be performed, its duration, start time and date. Fully unattended, automatic satellite tracking can therefore be planned a long time in advance.

The intuitive and user-friendly interface will plot the various satellite positions in real time, as well as show their transmission beam footprints superimposed on a world map.
