Antenna Positioner Systems

Date: 23.03.2016 Category: Aviation

Government facilities, international and commercial customers have deployed thousands of Antenna-Positioner Systems for a variety of reasons such as: range telemetry, flight termination, airborne and ground segment data link, target tracking, jamming, signal intelligence, and GPS. They cover both commercial and military frequencies and are available in omnidirectional for wide area coverage essential for tracking targets and locking in on directions for vehicles. These positioning systems can be placed on vehicles, can be portable for quick access or positioned strategically on base stations and can enhance any already existing antenna to work at maximum capacity.

Aerial Antenna Positioner

Similar to the antennas on all other military vehicles, they can be manipulated and specially formulated to fit the particular needs of those who use it. They can add or deduct capabilities to ensure the antenna itself is operating at maximum efficiency for the intended purpose. Positioners are no different, and it is not surprising they have a special positioner designed to detect and track unmanned aircrafts, manned helicopters and airplanes, but more importantly for fixed wing aircraft both for the defense and civilian industry. These are adaptable to the various weather conditions and various antenna types. These models have a mini sensor pack that includes magnetometer, accelerometer and GPS to ensure correct antenna position and pointing accuracy allowing for quick calibration and setup.

Size and Strength

Most positioners are 1.5 to 4.0 meters in size and gives the user optimal accuracy, flexible operation and reliability that gives the user peace of mind knowing their mission is being done correctly and unhindered by the various earthly interferences that may arise.

Equipment

Most positioners are equipped with mounting poles, depending on its intension can be mounted on vehicles, base stations or land bases. Positioners need a control unit, maintenance kit, AC and DC power, 100BASE-T Ethernet fiber optics and multi-bandwidth channels. They operate on 0.5-5.0MHz and can accommodate any antenna size or strength making this piece of technology adaptable to the rapidly changing military technological landscape.

Positioner Revolution

Like any piece of technology, whether it is a typical laptop or a complex spaceship, they all go through what I call “technological revolutions”.  What this means is that engineers and inventors are always coming up with new ways to improve already existing devices. We see it in everyday life as it is, think of your televisions; what was once a black and white bulky box that sits on a table in the corner of your room has morphed into a sleek, bright and vibrant wall ornament. Positioners are not the exception to the rule, they too are being transformed and improved upon. Engineers are putting in a single motor drive system resulting in far less than 0.01 degrees of backlash resulting in a much greater pointing accuracy making previous models obsolete. Using a single motor improves operation and reliability without the worry of exceeding already tight budgets. The control unit is also getting a makeover by using LINUX and COTS computer chassis providing the most power and performance at a reasonable cost.
