Über diese Lernkartei

Diese Lernkarten vermitteln die Grundlagen der Funknavigation für Piloten, wobei Frequenzen, Wellenlängen und technische Details wie MHz, Hz oder km im Mittelpunkt stehen. Es werden ILS-Kategorien, VOR- und NDB-Systeme sowie Signalausbreitung, Modulation und Reichweiten behandelt, inklusive typischer Fehlerquellen wie Refraktion oder Quadrantaleffekte. Ideal für Flugschüler und Piloten, die ihr Wissen zu Navigationssystemen vertiefen oder sich auf Prüfungen vorbereiten möchten.

Definition: Attenuation

Attenuation is the reduction of signal strength due to absorbtion, scattering and geometrical dispersion.

Amplitude Modulation (AM)

carrier wave is changed in the length of its amplitude. The frequency remains constant.

Frequency Modulation (FM)

The frequency is modulated and the amplitude remains constant.

Phase Modulation

This type of modulation is used by transmissions of digital signals and codes (00010110011011)

Pulse Modulation

Switching on and of the carrier wave. Morsing by transmitting the carrier wave pulses.
