CopterSonde Legacy

The CopterSonde is an uncrewed aerial system (UAS) developed at the Univeristy of Oklahoma for the observation of lower atmospheric conditions. Dr. Tony Segales (OU-CIWRO) is the main developer of the system, and continuous to work in the BLISS group as the engineer improving and supporting this system and expanding capaibilities generally. You can read about the detailed technical background of the CopterSonde in Tony’s AMT article and in the US Patent documentation. NOAA/NSSL has supported continued R&D on the platform, leading to a new version of the system — the CopterSonde SWX. See CopterSonde Versions for platform details. The CopterSonde has undergone NOAA Airworthiness tests, and is cleared to fly on NOAA projects. You can check out this story for history and information about the construction of the Coptersonde.

Jan 2019

Winter Wx

Deployments to KAEFS for winter weather. One of the most impactful datasets to date.

Jul 2018

LAPSE-RATE

Scoop refined. CopterSonde 2.5 developed and validated.

ISOBAR

First appearance of the “scoop” and the wind-vane flight mode. Campaign on Arctic sea ice. Record altitude reached (1.8 km).

Jun 2016

EPIC

NOAA UxS funded/led by NSSL. Octocopter design with sensors aspirated by the propellers. Ultimately did not perform to expectations and was impractical due to its size and weight. Led to Koch et al. 2018.

Jan 2015

CASS Established

Center for Autonomous Sensing & Sampling (CASS) was established, leading to the CopterSonde concept.
