Final answer:
DME operates at 960 - 1215 MHz, VOR at 108 - 117.95 MHz, Glidepath at 328.6 - 335.4 MHz, and LOC at 108 - 111.95 MHz. These frequencies are chosen for aviation navigation aids for their reliable propagation and minimal interference with structures.
Step-by-step explanation:
The frequencies of various navigation aids used in aviation, which include Distance Measuring Equipment (DME), VHF Omnidirectional Range (VOR), Glidepath, and Localizer (LOC), are part of the radio communication spectrum. Specifically:
- DME operates at frequencies between 960 MHz and 1215 MHz.
- VOR operates within the 108 to 117.95 MHz band.
- The Glidepath component of an Instrument Landing System (ILS) works within the 328.6 to 335.4 MHz frequency range.
- LOC, which is also a component of the ILS, operates on frequencies between 108 to 111.95 MHz, just like the VOR but uses a different subset of frequencies within this range for aviation navigation.
Each of these systems is designed to operate on specific frequencies to ensure reliable navigation and communication for aircraft. The selection of these frequencies takes into account factors such as signal propagation and the minimization of interference from buildings and natural obstacles. Aviation navigation aids are required to be precise and reliable, and therefore emit continuous signals that can be easily detected by aircraft navigation systems.
