Linux collects weather data at an altitude of 20 kilometres

Summary

A Gumstix computer logs GPS data, controls two cameras and sends position fixes by SMS from a high-altitude balloon. Pegasus 1 reached 66,585 feet. The mission took more than 600 pictures.

Ideas

  • Gumstix runs the mission logic under Linux.
  • GPS data documents the flight path and landing site.
  • Two cameras take pictures sideways and downwards.

Insights

  • Regular position reports increase the chance of a successful recovery.
  • Small Linux boards combine sensors, communication and storage flexibly.

Recommendations

  • Use redundant position storage and radio reports.
  • Test batteries at the low temperatures you expect.

Several Linux kernels run without a hypervisor

Hackaday presents Multikernel Linux, in which a host kernel divides up the hardware and starts further independent Linux kernels directly on bare metal. The project is called Multikernel Linux. It is not the historical microkernel-based MkLinux.
