Electromagnetic Solutions for Unmanned Aerial Vehicles

UAV-Resource-Page-2Electromagnetic Interference (EMI) is an electromagnetic emission that causes interference in another electronic device. EMI can be from intentional or unintentional sources, continuous or intermittent, at a single frequency or across a broad range of frequencies. EMI solutions are a crucial element in the design and manufacture of military defense products such as unmanned aerial vehicles (UAV). If a mission-critical system is not protected from EMI, it could malfunction or completely fail, input coordinates can be corrupted, and the communicated information may not be accurate.

Unmanned Aerial Systems (UAS) are air vehicles that do not carry a human pilot and are frequently used by the military. These remotely piloted systems are built with electronics susceptible to EMI, including ground control stations, guidance displays, sensors, flight controls, and communication signal translators. APITech has over five decades of experience in the design of mission-critical systems to suppress or eliminate EMI.

Filtered Circular Connectors for UAVs

CircularConnector72Filtered Circular Connectors: incorporate ceramic capacitors to strip unwanted electromagnetic interference (EMI) or transient voltages from signal lines. This type of connector provides an effective filtering device reducing the amount of real estate required within a product enclosure. Filtered circular connectors are most frequently used in Military and Aerospace applications, including unmanned applications.

  • Application description: commonly known as a drone, without a human pilot aboard consisting of UAV, ground controller, and a system of communications between the two, operating either under remote control by a human operator or autonomously with onboard computers.
  • APITech product: series of custom, circular filtered connectors designed to ensure the system functions accurately.
  • Why APITech? APITech has the EMC capability to test and design products specific to UAV requirements.
