proefballontrajecten

Proefballontrajecten are planned balloon flights used to study the atmosphere, validate instruments, or test aeronautical concepts by observing the path a balloon follows as it ascends. The term is common in Dutch-language contexts for controlled experiments with weather or research balloons, whose trajectories depend on atmospheric winds at different altitudes.

Planning focuses on selecting a target altitude, anticipated flight duration, and safe landing zone. Operators use weather forecasts and wind profiles to predict the trajectory and coordinate with airspace managers. Risk assessments and permits or NOTAMs are typically required to minimize disruption to other traffic and people on the ground.

During the flight, payloads carry instruments measuring temperature, pressure, humidity, and sometimes ozone or particulate matter, along with GPS and telemetry to track position. Data are used to improve atmospheric models, calibrate remote sensing equipment, and evaluate new materials or payload systems.

Tracking is done via ground stations, radar, or satellite links, enabling real-time monitoring of altitude and location. Balloons often carry parachutes or recovery mechanisms for payload retrieval after burst, though some missions are designed as non-recoverable.

Regulatory aspects involve aviation safety: coordination with national authorities, airspace usage, and compliance with local rules for flights over land or water. Proefballontrajecten are typically planned to minimize hazards to people and property and to ensure accurate data collection and instrument testing.
