Q-par All Weather Model 300 Series positioners are designed to be operated in a wide range of environmental conditions. To achieve this performance exceptional care is taken in tailoring the design of each positioner to the particular requirements of each customer.

The positioner body is designed for the minimum weight commensurate with the strength and ruggedness required for an all-weather unit. The main body of the positioner forms a sealed enclosure, with rotating weather seals for both the elevation and azimuth motions. The positioner can be fed with dry air, or supplied with passive dehumidification devices. A heat shield covers the top of the positioner, minimising the heating effect of direct overheat solar radiation.

The azimuth and elevation drive speed may be set according to the customer's demand. The system in the configuration shown, is capable of tracking, at a range of 1 nautical mile aircraft at speeds in excess of Mach 1.2.

The positioner incorporates an automatic guidance facility that utilises a high resolution, IR capable, camera to both locate and track targets.

The internal design of the positioner is the result of many years of experience and development. High quality electrical servo motors drive through zero-backlash cycling-plate gearboxes and high quality final drive gears to give a accurate and controllable drive train in all axes. Drive motor torques and gear ratios are selected to achieve the slew rates and pointing accuracy required for each particular application.  Axis position information is detected using high quality multi-bit digital encoders of appropriate accuracy. Factory set electro-mechanical stops are used to limit the positioner travel, for example, to prevent damage to an antenna dish. Electromagnetic brakes are incorporated to lock all axes in the event of power supply failure. Stowage pins are supplied to immobilise the positioner when not in use.

The antenna yoke is usually supplied with counterbalance masses to match the antenna to be used.  

A rigid plinth can be supplied to raise the positioner to a height appropriate to the diameter of the dish being used. This is configured as a weather-proof enclosure to house the Air Drying Unit.  

All parts of the positioner and plinth are treated with protective finishes (anodising, paint finishes as appropriate) to give corrosion resistance thus ensuring a long trouble-free service life.

The positioner can be operated from a standard PC or laptop (not supplied) using our standard GUI Control; the positioner is also available with an optional handheld controller unit. Both the GUI and the handheld controller can operate the positioner up to 1 km away.
