Set to launch in Q2 of 2019, FossaSat-1 will be Spain’s first satellite launch by a non-government led organization or company. FossaSat-1 is the next advancement in picosatellite technology, sized at only 5x5x5cm and weighing only 250g, it will be one of the smallest satellites ever launched into space.

This new pocketqube form factor allowed by the recent development in smartphone electronics will create a new satellite market never seen before, where satellites such as FossaSat-1 are being developed and launched into orbit for under EUR 30000, truly democratizing access to space for individuals, educational institutes and companies worldwide.

FossaSat-1 will provide free and open source IoT communications for the globe using inexpensive LoRa modules, where anyone will be able to communicate with a satellite fusing modules found online for under 5€ and basic wire mono-pole antennas.

The satellite is being developed by Fossa Systems, a non-profit juvenile association based in Madrid. The satellite is set to launch in Q2 of 2019 and will transmit LoRa and RTTY signals for anyone to receive using inexpensive LoRa modules, information on how to build these receivers will soon be published.

Specific information on each subsystem is explained in the github, a blog is maintained here.

All contributions are welcome and we are currently looking for software developers and machinists!

The satellite is based on an Atmega 328P-AU micro-controller, it uses an SX1278 transceiver as its main means of telecommunications. The EPS system is based on 3 SPV1040 MPPT chips.

  • Going forward!

    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!

Do You think about to use efficiency JT65 or FT8 modulation and Hoffman table tree alphabet code to boost and speed communication? Do You already develop some communication protocol according to best using power and efficiency of this satellite?

  Are you sure? yes | no

Hi Julian!

did you already choose the frequencies?

  Are you sure? yes | no

Hey Claudio, we are working in the UHF Amateur Satellite band (435-438 MHz) and are currently coordinating with the IARU.

  Are you sure? yes | no
