Hyper-local wind now casting using drone measurements
|Compensation:||Compenation provided by NLR|
The Meteo Sensors In the Sky (METSIS) project aims to test the use of drones as a wind sensor network for hyper-local wind now casting at low altitudes. METSIS consists of three steps:
- Step 1: Airborne drones measure instantaneous wind states and transmit data to a ground station
- Step 2: Ground station uses the Meteo Particle Model to estimate the wind field in real-time.
- Step 3: The ground station communicates wind field data to drone operators via the U-space weather information service
This master assignment focuses on step 2 of the overall METSIS project. For this task, METSIS aims to extend the Meteo Particle Model (MPM) , a technique for estimation wind based on aircraft flight, to low altitude urban airspace using drone measurements.
In collaboration with NLR, the MSc assignment is expected to start in September 2020, with a maximum duration of 12 months.
METSIS plans to perform a flight test with 4 drones in April 2020 at the NLR Drone Center in Marknesse to validate the METSIS concept. This will also be an interesting part of the master project.
The main research tasks include:
- Perform a literature review on the Meteo Particle Model and other relevant assimilation approaches
- Extend MPM to take into account the vertical motion of wind near the ground
- Adapt the model to cope with the wind in the urban low-altitude environment
- Develop a data acquisition and display system to visualize the wind field measured and estimated during the flight test
- Aid with the execution of the flight test
- Test and validate the model using simulation and real data from the flight test
- Recommend improvements to the METSIS concept, and report results
