How Does Starlink's Phased Array Antenna Track Satellites …
Nov 25, 2020 · In summary, Starlink has entered its public beta phase and people are more interested in the electronics than fast internet access. The satellite receiver uses a phased array antenna with hundreds of small antennas synchronized with precision to track satellites without mechanical movement. The receiver is sold for $499, possibly at a loss, and ...
What Happens When Using Long-Wave Frequencies with Starlink …
Jan 3, 2021 · The antenna elements in a Starlink phased array are connected to a central controller, which can adjust the phase and amplitude of each element. This allows the antenna to steer its beam towards a specific satellite in space, enabling two-way communication between the ground station and the satellite.
What makes antenna grounding "good"? - Physics Forums
May 22, 2021 · Push the ground rod in as far as you can so a lightning strike will go to ground, rather than through the power adapter, radio or computer. Keep lightning out of the house mains wiring.A "Rule-of-Thumb" for a "good" ground is an 8ft. (2.5M) Copper rod driven fully into the soil. This is adequate for power line grounding, and lightning rod ...
Basic phased array radar questions - Physics Forums
Jan 29, 2017 · A phased array radar is a type of radar system that uses multiple antennas to transmit and receive radio waves in a specific direction. By controlling the timing and phase of the signals transmitted by each antenna, the radar can steer and focus the beam of radio waves in a desired direction without physically moving the antenna. 2.
Help Identifying AESA Antenna Structure Type found in the F-35 …
Apr 30, 2018 · An AESA (Active Electronically Scanned Array) Antenna Structure Type is a type of radar antenna used in modern fighter aircraft, including the F-35. It is a flat array of transmit/receive elements that can electronically steer and shape the radar beam, providing improved performance and flexibility compared to traditional mechanical antennas.
TV antenna dish: depth, f/D, or focal distance - Physics Forums
Aug 28, 2021 · The focal length is the distance from the focus to the vertex. An offset dish is designed so the shadow of the LNA at the focus, and LNA support do not fall on the dish surface, so the vertex can be hard to find or missing. The approximate vertex is probably the surface of the dish that is closest to the focus support.
How to locate source of radio signal? - Physics Forums
Nov 1, 2011 · What equipment is needed to locate the source of a radio signal? The equipment needed to locate the source of a radio signal varies depending on the frequency and strength of the signal. Some common tools include a radio receiver, an antenna, a directional antenna, a spectrum analyzer, and a signal strength meter. 2.
Star like object travels in a zigzagging pattern relative to other stars
Jul 14, 2024 · Object was zigzagging relative to other stars. Only object that can zigzag would be a drone, but no drone can zigzag instantly like that. It looked like it was jumping. I have seen StarLink, ISS, and other satellites that “appear” to do that. Look up autokinesis.
Factors affecting the resonating frequency of wire - Physics Forums
Aug 30, 2005 · The wire will then be attached to a wheel of some sort that will allow weights to be attached in order to keep the wire tight. Regarding the factors, I have 3 so far, they are:-. 1) Length of wire used. 2) thickness. 3) tension the wire is under, varied by increasing the mass of the attached weights.
