We love Arduino and we love space exploration. So we decided to combine them and let people run their own space experiments!

New Ardusat Website Launched!

We're excited to let you know that today we've launched a brand new website for Ardusat! Over the last several months, we've been working to build our site and resources to better equip classrooms, clubs, and makers to create their own experiment to run in space. 

On, you'll now see free learning resources that cover topics from just understanding space in general, to lessons that help you understand various sensors on satellites and what they can measure. 

We plan to continuously build out this suite of learning resources and also would love the community to contribute back by sharing resources that you've built or used in the past. 

If you are a teacher and want more than just to use the free learning resources, contact us about our Classroom Space Kit. We'll send you hands-on materials for your students, provide first-class support, and provide additional opportunities for you and your students to engage in STEM topics like never before. 

This is a new milestone for Ardusat and we're thrilled to have you join us in expanding STEM innovation in space! For any questions, please send an email to

Mission Patches, SDK and Community Updates


Mission Patches for Ardusat-2

Today is the day that Ardusat-2 gets released from the ISS. If anyone has an idea for a mission patch, we'd love to see it. Our favorite design will get a mission patch with their design!

SDK Updates

Hi Everyone! We've made some great changes to the ArdusatSDK. Those updates include: 

  • Added Gyroscope library
  • Modified Accelerometer library to be compatible with I2C 
  • Improved overall handling of I2C communication 

Get the SDK:


Thanks to J.F. Omhover, there's also some great new tools for you to try out while you're working on your experiment. They include: 

  • AppStorage “emulators” : two libraries (SAT_AppStorageEMU, SAT_AppStorageEMUSD) to smoothly replace SAT_AppStorage during the development of your experiment, they divert all the output data to the Serial port or to a SD file
  • SamplingLib : series sampling for data reduction
  • DataLib : formatting scheme and decoder to send/read binary data from AppStorage
  • HeatShrinkLib (experimental) : a library to compress data 
  • I2C Scanner (sketch) : an I2C scanner that scans for available sensors connected to your Arduino’s I2C port, and outputs a comprehensive list 

 You can find Ardusat-utils at:

Finally, if you're a 3D printing aficionado, check out this thingiverse project to print your own Ardusat look-a-like (okay, it's a little more colorful than the real thing).

New Videos & Ardusat-1/X Experiments


Hey Everyone!

It's a been whirlwind adventure ever since Ardusat-1/X were deployed. We have to thank the Ham Radio community for helping track our satellites and download our beacons. They've been a great help tracking the health of our satellites!

We're hard at work getting ready to test and run your experiments. On that note, please start getting your experiments in. If you've already written code, you can email it to for an initial verification. Please make sure you're using the latest version of the SDK ( and that it compiles locally.

We've also added two new videos for you to use to learn more about Ardusat. Both cover orbits! The videos are both on Youtube and in the Ardusat Control Center. Don't be alarmed if the Control Center starts to change a bit in the coming month or so, we'll be doing a large update to it soon.

Ardusat-1 and Ardusat-X Deployed from ISS!


Very early yesterday morning, Ardusat-1 and Ardusat-X were deployed from the International Space Station. Shortly thereafter, they began transmitting their beacons! If you're a ham radio operator and you'd like to help track the beacons, we've added the details to the bottom this update. The Ardusat team is also hard at work running through an exhaustive number of system checks. Meanwhile, we have a number of great pictures to show you (courtesy of NASA/JAXA)! You'll notice that there are 3 satellites in the photos. The third is Pico Dragon - a cubesat from Vietnam!

The initial TLE for AS-1 and AS-X will be the same as the ISS until they put some distance between each other and are assigned their own Noad IDs. TLE for ISS: (What is a TLE?)

Both satellites will have a Morse beacon (FM-modulated 800Hz tones) that is transmitted at 20 WPM every two or three minutes on 437.000 MHz. The beacon will be structured in the following format:

ArduSat-1 beacon: Battery voltage (uint16_t), RX_counter (number of received valid data packets, uint32_t), TX_counter (number of sent valid data packets, uint32_t), “WG9XFC-1″

ArduSat-X beacon: Battery voltage (uint16_t), RX_counter (number of received valid data packets, uint32_t), TX_counter (number of sent valid data packets, uint32_t), “WG9XFC-X” Submitting a beacon packet:

You can submit a beacon as plain text to – be sure to put the word “packet” in the subject line so that we can parse it quickly. Submitting audio:

You can submit audio as an email attachment. Send an email to – with the audio file as an attachment.

* IARU recently reported the frequency of Ardusat as 437.325 MHz. The correct frequency is 437.000 MHz

New "Coding For Space" Videos and a Camera Example

1 like

Hello everyone,

Ardusat is still on track for release from the ISS at the end of November. That means the first experiments will be uploaded by the end of December or early January. We recently sent a survey to Kickstarter backers with experiment time. If you have a moment, please make sure you take the survey. It helps us plan out scheduling of the experiment uploads.

We've added four new videos to the Learn area of The new videos are a part of our "Coding For Space" series designed to teach space concepts and some basic Arduino programming. The videos are Serial Communications, Satellite Basics, Temperature Concepts, and Luminosity Concepts. We've also added quizzes and notes for each video.

On top of all that, we've added a camera example to the SDK. The way the camera is connected on the ArduSat (shared amongst all the components), it has to be told to take a picture in a unique way that's much different from just hooking it up to an Arduino on your desk. You can view the example at:

Happy Experimenting!
