Surveillance Data North Sea sensors
Air Traffic Control the Netherlands (LVNL) wants to receive signals from aircraft and helicopters above the sea, so that they can inform their air traffic controllers about the identification, flight altitude and location of air traffic. The Surveillance Data North Sea (SDNS) sensors are used for this.
The transponder on board an aircraft or helicopter is part of the avionics (the electronics used in aviation) and is an important part of air traffic control. This transponder receives and sends signals. An antenna receives signals from all aircraft and helicopters within range. These signals are made available to LVNL. By calculating the difference between the time of transmitting and receiving the signal, the distance to the antenna can be determined. By doing this for multiple antennas, the precise location of air traffic can be determined.
Data
For security reasons, it is not possible to request data from the SDNS sensors. LVNL is the only customer of the data.
