We know from Can we detect the cell phone, satellite phone, or walkie talkie of someone walking on Mars from Earth? that cell phone signals on Mars are potentially observable on Earth. I am not an ...

I just saw some footage of the ISS in which a dish antenna could be seen, constantly rotating. The dish looked more-or-less parabolic, meaning that it is presumably sending/receiving along a fairly ...

I guess that everyone is familiar with the problem of aligning a TV satellite dish: some degrees off and the signal you desire is gone. How sensitive is communication with deep space probes to this ...

I've read the following passage in the answer to the Quora question How can Voyager send a signal strong enough for us to receive, in spite of its enormous distance from us? And how can it have the ...

Whenever communications to/from a space vehicle are described or discussed, there is inevitably a reference to the vehicle's "high gain" antenna. What is it about such an antenna (specific technical ...

What is the main function of high and low gain antennas? Do all satellites and space probes have high and low gain antennas?

According to The Pioneer Missions, my emphasis, The Pioneer 11 Mission ended on 30 September 1995, when the last transmission from the spacecraft was received. There have been no communications ...

I assume (but I may be wrong) that in a communication satellite constellation such as the one spaceX plan to put into service: each full duplex link requires a dedicated antenna each satellite ...

Suppose Mars Odyssey (ODY) and the Mars Reconnaissance Orbiter (MRO) are being tracked by antenna A (just for example) at the Goldstone Deep Space Network complex in MSPA mode. Is it possible for ...

above: from Facebook, then annotated. There is an excellent review of the design of the TESS spacecraft in G. R. Richter et al. Journal of Astronomical Telescopes, ...

This question is inspired by an answer to this question, where it is stated that: The real power of phased arrays is their ability to be steered electronically. This set me wondering about the ...

Can a cubesat in orbit be operated like a R/C airplane in real time? edit: if the link here and the end aren't clear, I'm interested in the ease and convenience of access, the frequency of possible ...

I spotted this tiny, articulated dish antenna-like thing on the Zvezda module of the ISS while looking around for images for here. It looks like it's associated with and/or pointing in the same ...

Supposing I wanted to connect to the ISS's WiFi network from the ground, how large of an antenna would I need to do so, and what kind? Would they need to increase the power on their end or use a ...

I learned about the Kurs docking system in this answer, then found out what they looked like in this and in this answer. Those images show several tiny dish antenna structures sticking out from ...
