What Antenna Attitude Sensors Do

What Antenna Attitude Sensors Do

As technology moves at a fast pace, many innovative devices are being developed for a number of applications. In recent years, some of the most important advances have been made with antenna attitude sensors. Used in a variety of areas including space exploration and satellite communication, antenna attitude sensors play a pivotal role in ensuring all signals and transmissions are able to be completed without any problems. However, despite their importance in so many critical areas, many people are still unclear as to why these sensors are so vital in today’s world.

Antenna Positions
With many high-tech devices being relied on to record accurate measurements, antenna attitude sensors make sure the antenna position stays where it needs to be for this to happen. Usually a permanently mounted, fully-integrated monitoring system, the sensors take measurements daily to ensure the antenna’s alignment does not change from its designated position. Updating measurements instantly, the sensors are then able to transmit data regarding the azimuth, tilt, and roll of the antenna to virtually anywhere in the world, allowing technicians to make any necessary adjustments.

Optimization Analysis and Investigation
In situations where antenna positioning may be the cause of poor performance, antenna attitude sensors allow for optimization analysis and investigation. In doing so, current antenna alignment can be reported to Remote Electrical Tilt controllers, who can then perform various troubleshooting techniques. In doing so, the sensors can relay specific latitude and longitude specifications to measure the antenna’s azimuth within one degree of accuracy.

Absolute Attitude Sensors
One of the most important uses of antenna attitude sensors involves their use with the nation’s space program. Using the position of the sun, the sensors are able to sense the position of objects located outside a spacecraft. For example, horizon sensors rely on thermal infrared sensing to measure the warmth of the atmosphere, allowing the spacecraft to determine its orientation to Earth. Another use of the sensors is to sense magnetic field strength, which is critical as a navigational aid for the spacecraft. Very popular due to their low cost and reliability, they allow attitude to be determined when the spacecraft’s position is compared to a map of the Earth’s magnetic field, which is usually stored in an onboard computer.

Motion Referencing
In addition to being used for space exploration, antenna attitude sensors are also used in many other applications. These can include:
–Ocean wave measurements
–Ship motion monitoring
–Antenna motion compensation and stabilization
–High-speed craft motion control
These applications, which have proved useful to various industries, have led to numerous advances in safety and efficiency.
While technology continues to advance in this area, it’s clear antenna attitude sensors will play a pivotal role in many industries in the years ahead. As more discoveries are made, there’s little doubt that everything from satellite communication to oceanography will be greatly impacted by these sensors.
