Back with another update after several weeks! FossaSat-1 progress is coming along nicely and I am proud to announce we have started construction of the flight models. Final thermovacuum and vibration testing is being carried out the 17th of July and integration of the satellite is being done in early September for a launch in October.
SInce pictures are worth more than 1000 words, i'll leave it up to them to tell the story and current state of the project :)
- Satellite Holder for assembly (starting next week)
- LACADIO URJC Cleanroom where FossaSat-1 is being built by 16 year-old Julian Fernandez.
Network analyzer testing of FossaSat-1, VSWR of 1.04 Achieved!
28% efficient gallium arsenide cells, a total of 233 here totalling 7.8W and being just enough for 2 FossSat-1 flight models
Alumnium Shakerbox for random and sinusoidal vibration of FossaSat-1
Finished electronics of FossaSat-1. Seen below are the EPS and COMMs/OBC boards. The EPS is based on the SPV1040 MPPT controller and the TC1262 LDO. OBC/Comms is based on the Atmega 328P-AU as CPU, SX1268T with TCXO as transciever, TMP100 Temperature sensor, INA 226 Current and voltage sensor, MAX6369 Watchdog for SEU protection, TPS2553 for SEL protection and various mosfets for deployment of solar panels and antennas.

Hello Everyone, @EA4HCD here!
Just wanted to inform everyone on Hackaday that the project is progressing as planned, we will be starting to assemble the final Flight models in the clean room in a couple of weeks and have just received our IARU frequency spectrum allocation for LoRa of 125kHz. We will soon be publishing extensive guides on how to decode from FossaSat-1!
A shoutout to Jan Gromes for developing SX1262 support for RadioLib which will fly into space!
Excuse the lack of updates, have not had much time!
We post weekly updates on our twitter @FossaSys
Here a are some pictures of our progress so far, more to come!
