Automated Radiosonde Tracking Via Open Source

Filed under
OSS

Meteorological organisations across the world launch weather balloons on a regular basis as a part of their work in predicting whether or not it will rain on the weekend. Their payloads are called radiosondes, and these balloons deliver both telemetry and location data throughout their flightpath. Hobbyists around the globe have devoted time and effort to tracking and decoding these signals, and now it’s possible to do it all automatically, thanks to Radiosonde Auto RX.

The basis of the project is the RTL-SDR, everyone’s favourite low-cost software defined radio receiver. In this case, software is used to first hunt for potential radiosonde signals, before then decoding them and uploading the results to a variety of online services. Some of these are designed for simple tracking, while others are designed for live chase and recovery operations. Currently, the software only covers 3 varieties of radiosonde, but the team are eager to expand the project and have requested donations of other radiosondes for research purposes.

  • Intel Iris Gallium3D Picks Up Conservative Rasterization Support
    On top of Intel's new open-source OpenGL driver seeing some hefty performance optimizations, the Iris Gallium3D driver has picked up another OpenGL extension ahead of the Mesa 19.1 branching.  Iris Gallium3D now supports INTEL_conservative_rasterization alongside the existing support in the i965 driver. INTEL_conservative_rasterization is the several year old Intel extension for seeing if all fragments are at least partially covered by a polygon rather than the default rasterization mode of including fragments with at least one sample covered by a polygon.
