Aircraft radar altimeters operate within 4.2–4.4 GHz, the lower half of which falls within the C-Band—a frequency range from 3.7–4.2 GHz where the combination of the range of signal ...

Garmin has introduced its first radar altimeter, the GRA 5500, an all-digital design intended to bring extremely high altitude accuracy to general aviation aircraft.

FreeFlight Systems has completed the first round of formal testing on their new 5G friendly radar altimeter—with encouraging results, says FreeFlight Systems president Anthony Rios.

The radar altimeter was implemented to make air travel safer for both pilots and their passengers. But if the complications brought forth by the deployment of 5G technology are not dealt with, ...

Radar altimeters measure altitude above the terrain beneath an aircraft by timing how long it takes a beam of radio waves to travel to the ground, reflect, and return to the craft.

The initial C-band plan was to use signal frequencies of 3.7 to 3.98 GHz, but that’s too close for comfort to the operating radar altimeter frequency band of 4.2 to 4.4 GHz.

These radar altimeters may send out a signal and be unable to discern the reflected signal because of energy from the faraway 5G towers entering the receiver, ...

While radar altimeters made for military aircraft are sometimes built to slightly more stringent requirements — having the ability to function in extremely cold or hot environments, for instance ...

A plan to sell spectrum is generating warnings that the move may interfere with sensitive aviation instruments like radio altimeters.

New York, United States , Aug. 12, 2024 (GLOBE NEWSWIRE) -- The Global Radar Altimeter Market Size Expected to Grow from USD 36.97 Billion in 2023 to USD 55.02 Billion by 2033, at a CAGR of 4.06% ...

OSAS pointed out that the radar altimeter in question was manufactured in 2020, and that the model is widely used. Apparently, CTIA mistook the model’s authorization date for that unit’s age.
