engines - Why can't Voyager 1 finally "settle down" to a stable ...
Sep 21, 2024 · The attitude thrusters on the Voyager spacecraft have a minimum on time of 15 ms (some claim 8 ms). The low-level thruster controllers are fairly high rate digital controllers. The valve that feeds the thruster is commanded to be open or closed for the duration of each fixed duration thruster controller time step.
spacecraft - Why is Voyager 1 faster than all other space probes ...
Aug 13, 2017 · Although other probes were launched first, Voyager 1 was able to achieve a higher speed and has overtaken all others. Voyager 1 overtook Voyager 2 a few months after launch, on 19 December 1977. It overtook Pioneer 11 some time in the late 1980s, and then Pioneer 10—becoming the probe farthest from Earth—on February 17, 1998.
communication - How does Voyager 1 send signals to Earth?
Source: Wikipedia on Voyager 1 - Communication system. The Voyager 1 communication is received on Earth by the Deep Space Network (DSN): NASA's Deep Space Network (DSN) has been in partnership with Voyager 1 and Voyager 2 since 1977, providing daily communications support to the two very distant spacecraft.
What are the parameters of the Voyager high-gain antenna?
Apr 8, 2024 · The Voyager spacecraft have a 3.66 m diameter parabolic high-gain antenna. I've had a nose around NASA's archives but I can't find the exact geometry of the parabola; specifically the distance from the vertex to the focus, the latus rectum or alternatively the quadratic equation of the parabola.
Does the Voyager team use a wrapper (Fortran (77?) to Python) to ...
Aug 7, 2019 · The Voyager spacecraft are still being patched as of 2023. The uplink is only 16 bits/second, just enough to send (simple) commands. How these commands are generated is irrelevant to the spacecraft. Any language that can generate a sequence of …
Why were the Voyager spacecraft numbered "out-of-order"?
From wikipedia "On November 7, 2012, Voyager 2 reached 100 AU from the sun, making it the third human-made object to reach 100 AU. Voyager 1 was 122 AU from the Sun" , "In 2013 Voyager 1 was escaping the solar system at a speed of about 3.6 AU per year, while Voyager 2 was only escaping at 3.3 AU per year.[41]
Every day, how much speed does Voyager lose due to the sun's …
Dec 5, 2024 · The Voyager spacecraft will never be pulled back into the sun because it achieved escape velocity. But it's moving away slower and slower all the time. Voyager is currently moving away from us at 31,000 mph. Every day, how many MPH does voyager slow down? Illustration: kind courtesy of NASA/JPL. It's so far away that it can't be much.
nasa - Voyager 3: what would have been its mission, and why was …
A third Voyager mission was planned, and then canceled. Apparently, Voyager 3 was cannibalized during construction: I am currently reading the book Voyager: Seeking Newer Worlds In The Third Great Age Of Discovery by Stephen J. Pyne. On the second chapter, it is listed that there were three Voyager spacecraft.
Did the Voyager spacecraft use a Golay, a Reed-Solomon and/or a …
Jul 10, 2021 · For the 1977 Voyager mission, the Jet Propulsion Laboratory (JPL) used a (255, 223, 33), 16-error-correcting RS code over $\mathbb{F}_{256}$ as an outer code, with a rate-1/2, 64-state convolutional inner code (see also Section IV-D). The RS decoder used special-purpose hardware for decoding, and was capable of running up to about 1 Mb/s [27].
How does Voyager 1 keep track of its orientation?
Dec 5, 2017 · Voyager 1 and Voyager 2 use the same Attitude and Articulation Control Subsystem (AACS) to maintain the crafts orientation; facing the antenna towards the Earth. Voyager's AACS system uses a sun sensor for yaw and pitch reference, and a star tracker trained continuously on a bright star at right angles to the sun point for a roll reference. Links:
