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: https://github.com/ArduSat/ArduSatSDK

Ardusat-utils

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: https://github.com/jfomhover/ArduSat-utils 

3D Printed Ardusat

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).

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 nick@nanosatisfi.com for an initial verification. Please make sure you're using the latest version of the SDK (https://github.com/ArduSat/ArduSatSDK) 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.


Update #26

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: http://www.celestrak.com/NORAD/elements/stations.txt (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 nanosatisfi@gmail.com – 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 nanosatisfi@gmail.com – 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


Update #25

New "Coding For Space" Videos and a Camera Example

Comment
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 Ardusat.org. 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: http://ardus.at/camexample

Happy Experimenting!

The ArduSat Team


Update #24

Official ISS Deployment Date / New Videos & Quizzes

Comment

Hi All,

We hope that you had a chance to watch the launch of ArduSat to the ISS last month, and continue to be as excited as we are that our satellites are at this moment in space. We have some breaking news to share that just came to us from JAXA about the date that ArduSat is thrown out of the ISS into orbit. The official date to anticipate is November 25, and we’ll be sending more information closer to the date on how you can celebrate this next milestone with us. The date is much later in the year than we expected, and we are a bit disappointed that all of our ArduSat users will have to wait a few more months before getting access to the satellite. JAXA decided on the November date so that a Japanese astronaut can be on-hand at the ISS for the deployment, and everything was pushed back to accommodate this decision. While the final deployment date is out of our hands, the good news is that it gives you slightly more time to look through our resources online at control.ardusat.org (please use Google Chrome for a complete experience) and to plan your experiment.

We are pleased to announce that we are starting to roll out a new series of video tutorials to complement the existing individual sensor videos that have been available all year. This new series of tutorials are designed to take a complete beginner from knowing absolutely nothing about Arduino or satellites to collecting data for a pre-built experiment from ArduSat. Along the way, users will be introduced to basic Arduino programming, useful space concepts around temperature, light, and the electromagnetic spectrum, and ideas for using some basic Arduino sensors for at-home experiments that can help spark ideas or create opportunities for comparison with data collected in space. The tutorials continue to be short videos with quizzes, and include related content such as definitions lists, fritz diagram and code downloads, and a curated list of other useful links.

The first few new tutorials are posted in the learning section of the ArduSat Control Center and additional videos will be added over the next month. Log in to control.ardusat.org and click on the Learn tab. Here is an overview of the new videos that we have added, in the order that we recommend watching them:

  • Educational Kit – absolute beginner video that introduces the Arduino board and identifies the basic components and sensors used in the tutorials.
  • Blinking LED – introduction to the standard first Arduino project and how to navigate the ArduSat Control Center
  • Structuring Code – a beginner primer on how Arduino code is structured and a few key commands to memorize
  • Blinking Light Revisited – walk through of the blinking LED project that focuses on the circuit set-up and line-by-line code explanations
  • Photoresistor Project 1 – introduction to photoresistors, the circuit set-up, and basic code
  • Analog vs Digital – simplified overview of the difference between analog and digital signals and why the distinction is important in Arduino programming

This new set of videos is a great way to get started if you have been putting off designing your experiment, continue to be unsure of how to get started, or just want us to walk you through exactly which data to collect and how to analyze it. Please take a look and let us know what you think. Coming soon are tutorials on temperature concepts in space, luminosity concepts in space, an introduction to serial communication, an LDR project that simulates a satellite attitude control system, and two pre-built experiments using the temperature and luminosity sensors.
