Sirius Rocketry - For the Serious Rocketeer!

Altimeter Three


  • Model: JL ALT3
  • Manufactured by: Jolly Logic

The Jolly Logic AltimeterThree is a flight altitude recorder that is controlled by your smartphone or tablet. If you would like to collect and share flight data, then this is the altimeter for you. It is small enough to go almost anywhere, and it can used for almost any flying activity; rocketry, model airplanes, model helicopters and quadcopters, gliders, kites, raptors and more.

It captures your notes and observations on each flight. You can view an interactive graph of altitude (and for certain sports, 3-axis acceleration) and produce a Microsoft Excel™ spreadsheet of flight data for further analysis. If GPS is enabled on your phone, the location of each flight is saved, and can be viewed on a map. Integration with Facebook, Instagram, Twitter, and Flickr allow you to share your flights with just a tap.

The AltimeterThree includes a recharging cable, and can be recharged from any USB port. We suggest you install and test the app before purchasing the altimeter, to make sure your device is compatible.

  1. AltimeterThree requires a compatible smartphone or tablet with Bluetooth (you cannot use the altimeter by itself)
  2. Before purchasing the Altimeter Three, download the free mobile app from Apple, Google, or Amazon and try it before buying (to make sure that they are compatible; app download links below)
  3. This is a great altimeter for science projects and research! (In addition to pretty screens, it produces real Excel spreadsheets for data analysis.)
  4. This is the ONLY altimeter approved by Apple as an accessory, and the first to feature social media integration (Facebook, Twitter, Flickr, Instagram)
  5. The optional Snap Mount fits all Jolly Logic altimeters for mounting.
  6. With the lastest release of the Altimeter Three mobile app, Altimeter Three now performs the "Altimeter Two" flight analyses for rocket flights (including existing flights already flown) and labels them on the graph. It also adds a second descent rate labeled on the graph so that you can the descent rate before and after dual deployment. So it’s now “Chute Release aware.”
