Hey nice video! as an option you can also consider LoRa as a transceiver. This is pretty cheap and some companies use it as a redundant communication module
Iridium data is really expensive. I would go with an SDR transceiver. There are a fair number of open source designs out there. A LimeSDR could act as both a GPS receiver and radio transceiver, I believe simultaneously. Having one or more reconfigurable radios would give you an incredible amount of utility. Standard Lion chemistries are destroyed when charged below freezing so I don't think you can use normal ones.
Hey Alex! Thanks for the feedback. You are right, Iridium data is expensive. The benefit of using that service is that I wouldn't need my own groundstation setup to receive data. To put it another way, I can bypass all sorts of radio related challenges (which are interesting, but are beyond the scope of this project) by simply relying on iridium. As for li-ion charging while code, you are right again. The simple work-around is to add some heating elements to the batteries, and only charge when some ammount above freezing.
Really like what you have done, I like Lora as a comms system as there are already ground stations world wide that you can use and check on them over the internet for free. When it comes to geeks there are many of us and we like to help each other.
OK, the components has a great temperature range for earth. But the temperature in space is much lower, about -270°C. Will it survive these freezy conditions?
Deep space may be that cold, but Low Earth Orbit isn't! It depends on your orbit & how much you rotate, but I'm not too concerned about temperature. space.stackexchange.com/questions/35547/temperature-of-a-satellite-orbiting-in-low-earth-orbit
@@RGSAT Is lower power better than high speed? I know for quadcopters they try to use the fastest MPUs available for a smoother ride. But they draw a lot of current.
Can save you a bunch on the power management system. Which is configured for 3ea. 18650s which will also save you $6 for one less $18650. But given this video is so old no sence posting part sources

bro ive been wanting to build a cube sat for a some time so this is grait help thanks defo helping alot keep it up!
Glad I could help!
Great work. Any more updates ?
Working on it! I'll have another video up soon

Nice work man
Just put lora tranceiver, and use the tinygs network to communicate.
Great explanation.
Look at something like the 2020 Ali extrusion for the structure. Could do it for like $50-70
Please help can you tell me the measurements for all parts because it's not clear
Many thx for sharing.
What new innovations can be for power subsystem?
How will you launch the sattelite

How to build a command and control system
Can you not use Carbon Fibre for the frame?
Are you planning on launching this and if so what company
Bro I want to contact you
Helo brother i want help
Sir Can i use STM32 F4 INSTEAD OF L4 CUS ITS NOT AVAILABLE IN AMAZON INDIA
You can use any microcontroller you'd like! I simply chose the L4 series because I'm familiar with it, and it is intended for low-power applications.

will you also build a remote radio dish to track it?
A remote dish and a computer to track and control it
Dude wouldn't a cell phone work
There has been a phone launched in a cubesat! www.nasa.gov/directorates/spacetech/small_spacecraft/phonesat.html
