Detecting GPS jammers is crucial for ensuring the integrity and reliability of Global Positioning System (GPS) signals, particularly in environments where jamming devices disrupt navigation and communication systems. These jammers emit radio frequency signals that interfere with legitimate GPS signals, leading to significant disruptions. To locate these jammers, advanced techniques such as Angle of Arrival (AOA) and Time Difference of Arrival (TDOA) are utilized. AOA uses phased array antennas to determine the direction of the jamming signal, with algorithms like Multiple Signal Classification (MUSIC) and Minimum Variance Distortionless Response (MVDR) enhancing accuracy. TDOA, on the other hand, triangulates the jammer’s location by measuring the time difference between signal arrival at multiple sensors. The integration of unmanned aerial vehicles (UAVs) equipped with directional antennas and sophisticated algorithms further improves the real-time detection of GPS jammers. These UAVs can cover large areas quickly and provide precise bearing measurements, making them invaluable in both military and civilian applications.

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
