A system for automatically preselecting an aircraft voice radio communication frequency when operating on or near the airport surface. An extension of this invention can also be used in flight. A sensor input m
High Frequency radio data link has been found to provide better availability than HF voice on trans-Polar routes beyond the 80-degree North/South limit of Inmarsat satellite coverage. The HFDL capacity is only limited by the frequencies available in the HF band. The allocation of HF frequencies ...
reception of status information for a radio-frequency communication of said radio-frequency transceiver (<B>2, 3, 4</B>) and a first man/machine interface (<B>5</B>) which displays at least one set of configuration information for said radio-frequency transceiver device (<B>2, 3, 4</...
Every country has a governing authority that allocates a specific operating frequency for a small satellite mission. The International Telecommunication Union (ITU) Radio Regulations regulate the utilization of radio frequencies and the law of nations scale radio-communication services. However, the proces...
The microphone is a primary input to the Communication Transceiver and its job is to convert sound into an electrical signal. Sound is caused by a disturbance in air molecules and produces waves with frequencies of 20 to 20,000 cycles per second. As a person speaks, air molecules are c...
Very high-frequency radio communications are the most abundant example of pilot communications, accounting for nearly every pilot/controller interaction on the ground and in the air. VHF radio frequencies are allocated to multiple industries, with aviation and marine navigation being two of the most ...
The present invention relates to a device 1 for allowing the use in a aircraft A of at least one radio communication apparatus (R), such as mobile telephones. According to the invention, the radio communication apparatus (R) includes a first connection switch (MC1) between an information ...
Frequencydetermines the line of communication between a receiver and transmitter. The transmitter and receiver must both be on the same frequency so the plane can be controlled. Reserved frequencies Many countries reserve specific frequency bands (ranges) for radio control use. Due to the longer rang...
With its ability to receive FM, AM, SW, VHF, and CB frequencies, this radio is a one-stop solution for all your radio needs. Whether you're an aviation buff, a trucker, or a radio hobbyist, this radio has got you covered. The inclusion of the air band reception (118-138MHZ) and...
Although specific portions of the frequency spectrum (i.e., all the values of f to be used) must be allocated to prevent different systems from interfering with each other, for many years and by general agreement, radio transmission frequencies have been designated in the following “bands” (...
