Dropsonde System for Unmanned Aerial Vehicles
Project Description
A small, modular dropsonde launcher is being developed for Unmanned Aerial Vehicles (UAVs). Some critical measurement needs can only be satisfied by in-situ measurements. Key examples of such measurements include detailed atmospheric profiles, point meteorological conditions on the surface, and in-situ measurements for calibration and validation of remote sensing systems. Phase I work saw the design and fabrication of a new type of dropsonde with a novel form factor and the associated launcher. The system was installed in a representative UAV nose. System components were successfully tested. Phase II will involve finalizing the launcher and dropsonde designs, developing the associated control and data handling system, building and testing the integrated system, and finally conducting test flights on a UAV. The ultimate result of the project will be a dropsonde system that can be fitted to many NASA UAVs, including small UAVs, and enable them to gather in-situ atmospheric profiles and surface measurements using dropsondes. The Phase II entry TRL is 5; the expected exit TRL is 8.

Anticipated Benefits
Other agencies engaged in the use of UAVs for atmospheric research or operational meteorology measurements (e.g., NOAA and the Department of Defense) would be able to use this dropsonde system on their UAVs. Elements of the system, such as the dropsondes themselves, may be applied in other dropsonde launchers deployed on other platforms as well. A radiosonde derived from the dropsonde will potentially meet the needs of the very large radiosonde market.
Several areas of NASA research will be able to make use of dropsonde-equipped UAVs. One prominent area that will benefit is hurricane research: dropsondes would bring a new dimension to the data gathered by UAVs flying into hurricanes, making their measurements more comparable to those of manned aircraft. A second area is wildland firefighting operations: dropsondes would allow the UAV to return local meteorological profiles that could be used to improve the point weather forecasts developed by fire meteorologists. Atmospheric and polar research are two more generic areas of research which will benefit from a dropsonde system for UAVs. More »
