The range from 108 to 117.975 is for aeronautical radionavigation.
2.
Code division multiple access ( CDMA ) networks tend to use handset-based radiolocation technologies, which are technically more similar to radionavigation.
3.
CDMA networks such as Verizon Wireless and Sprint PCS tend to use handset-based radiolocation technologies, which are technically more similar to radionavigation.
4.
At the beginning of the 20th century, some ships communicated by underwater bells, the system being competitive with the primitive Maritime radionavigation service of the time.
5.
Using hyperbolic geometry and radionavigation principles, a position fix with an accuracy on the order of was realizable over the entire globe at any time of the day.
6.
For example, in the United States, signal leakage from cable television systems is regulated by the FCC, since cable signals use the same frequencies as aeronautical and radionavigation bands.
7.
"' Radio navigation "'or "'radionavigation "'is the application of radio frequencies to determine a position of an object on the Earth.
8.
The most significant projected vulnerabilities are those associated with the modernization of the National Airspace System and the plan to adopt the Global Positioning System as the sole basis for radionavigation in the United States by 2010.
9.
Radionavigation aids located on the ground, such as VORs, are also checked and updated to keep them aligned with magnetic north to allow pilots to use their magnetic compasses for accurate and reliable in-plane navigation.
10.
An en-route ( also known as en route or enroute ) chart provides detailed information useful for instrument flight, including information on radionavigation aids ( navaids ) such as airways, airport locations, minimum altitudes, and so on.
