Radar Systems

A radar is a system that uses radio waves to detect the presence, location, and movement of objects. When an object is present, radio waves will reflect and be picked up by a receiver. With multiple pulses, the velocity of the target is determined by comparing the change in distance over a period of time. Lidar (Light Detection and Ranging) works with the same principle but uses light instead of radio signals. Typical use cases for radar include air traffic control, ship tracking, weather monitoring, and military object detection.

Communication and Datalinks

Communication systems involve transmitting information from one person or system to another. The technology is often radio-based, sending and receiving radio signals by communication systems. Communications can also use wired transmission, laser-based, or other forms of datalink. Datalinks operate between the onboard sensors (e.g., airspeed) and a computer for processing. Typical requirements include security, high reliability, and high data rates, which are most commonly used in air traffic control, ground-to-air, air-to-ground, air-to-air, satellite, ship communications, and datalinks.

GNSS is the most often used method for aircraft navigation. This includes UAV/drone guidance, flight control systems, and autopilots. Ground navigation GNSS systems use “trilateration,” where the distances to three or more known reference points are used to determine the position. An alternative to GNSS, aircrafts can use an Inertial Navigation System (INS). These use multiple motion sensors such as accelerometers and rotation sensors to recognize the position relative to an initial reference point. The INS systems are immune to GNSS jamming, making them suitable for defense aircraft and equipment in GNSS-denied operations. Applications include Flight control systems, Flight Control computers (FCC), UAV/drone guidance, navigation instruments, and autopilot systems.
