Satellite technology is a fascinating field that makes use of some very clever engineering to overcome the challenges of designing for the space environment. This video explores the seven subsystems - the structure, the on-board computer, the electrical power system, the attitude determination and control system, the propulsion system, the communications system and the thermal control system - that make up a typical satellite bus.

@sethwhite4155 4 месяца назад

Nice video! I used to work in rad-hard electronics and its crazy how important it is to rad-hard your components, sub-system, and once you have that put together test the whole computer system. Looking at you starlink 👀. In my basic understanding, satellite design is not to design to prevent complete failure from radiation, its to design around it. The electronics degrade over time and normally designers will put multiple circuits in and will rotate them out after a defined amount of time. Semiconductors degrade much faster when they are energised vs when turned off in rad environments.

@stuartgray5877 4 месяца назад

Did you know that all of SpaceX's original electronics came from Digikey? That is UNTIL they started flying payloads for NASA. Then they were required to use rad-hard parts. I wonder WHY the astronauts onboard the ISS can still use iPods and Apple Laptops?

@stuartgray5877 4 месяца назад

And how many of SpaceX's initial flights failed due to radiation effects? ZERO.

@Snookers_ 4 месяца назад

@@stuartgray5877 Digikey sells rad-hard components too. Also, the ISS exterior already has significant radiation shielding. If it can protect humans, it can probably protect your electronics too. I'm guessing any critical devices will be hardened, but someone's iPod failing is far from mission-critical. It's also a whole lot cheaper to replace a non-critical (or backed-up) iPod or laptop than it is to have a team of engineers design a rad-hard version.

@stuartgray5877 4 месяца назад

@@Snookers_ I know all that. SpaceX was using non-rad hard parts at first. They even asked me what I thought of that when they interviewed me for a job on Dragon Avionics. I said the the same thing I said above: NASA won't let you you Keep doing that for manned missions. I was correct. They offered me the job but I turned it down. I'm too expensive for them I'll be kicking myself once they go public as the signing bonus was a LOT of shares. I was told by a colleague that went there they work a LOT of OT without pay. I'm too old for that.

@Snookers_ 4 месяца назад

@@stuartgray5877 Ahh, I definitely misinterpreted your original comment. I've heard a lot of people talk about their experiences working at SpaceX and it all seems to be pretty similar - lots of unpaid overtime, and lots of half-regrets from people leaving when they did. I've also heard a few other very interesting stories regarding SpaceX that I probably wouldn't have believed if I didn't have absolute trust in the person they came from...

This video reminded me of my first internship where I got to built a cubesat and really provides a basic overview about the main things about satellites. However, I would like to add one thing at 12:12 . When reaction wheels reach their saturation, it does not mean they cannot be used anymore. If they are played in a coil, their rotational energy can be converted into electrical energy which will slow the reaction wheels down, while also providing power to the satellite.

"articulated solar arrays" -- how does that affect the attitude/orientation of the satellite? if the solar panels change position, that must have an effect on the satellite right? because if velocity is constant and it's at orbital velocity, there's nothing except that mass of the satellite for the motors orienting the panels to react against? i think?! i'd never thought about this till the video mentioned it

The real chore is to fling that satellite fast enough, so that it not only gets into the vacuum of space, but also angled that as it falls back, it misses the ground. This works with a spherical Earth, as the physics for a flat Earth makes it a tad harder.
