Gogo's air-to-ground (ATG) network is a cellular radio network (meaning that there is a hand-off when the aircraft moves between service areas) that has more than 200 towers in the continental U.S. and Canada. [13] The ground stations consist of original Airfone air-ground phone relay stations and newer locations, using the 850 MHz ATG band.
where = (), is the horizontal distance between the UAV and the ground node, and are the terminal heights, is the ratio of land area covered by buildings compared to the total land area, is the mean number of buildings per km 2, and is the scale parameter of building heights distribution (assumed to follow a Rayleigh distribution). In some cases ...
The network consists of dedicated tactical links, wideband air-to-air links, and ad hoc networks constructed by the Joint Tactical Radio System (JTRS) networking services. JTRS is a software-defined radio that will work with many existing military and civilian radios.
2012: Capability Set 14 to provide Universal Network Situational Awareness to help prevent air-to-ground friendly fire incidents. [ 2 ] May 2016: Harris Corp. is awarded a $405 million contract by Moroccan Army concerning SINCGARS system equipment including ancillary items, spare parts, installation kits, training and fielding support services.
Multifunctional Information Distribution System (MIDS) is the NATO name for the communication component of Link-16.. MID is an advanced command, control, communications, computing and intelligence system incorporating high-capacity, jam-resistant, digital communication links for exchange of near real-time tactical information, including both data and voice, among air, ground, and sea elements.
Example of an ACARS message. In aviation, ACARS (/ ˈ eɪ k ɑːr z /; an acronym for Aircraft Communications Addressing and Reporting System) is a digital datalink system for transmission of short messages between aircraft and ground stations via airband radio or satellite.
Air-ground radiotelephone service is a system that allows voice calls and other communication services to be made from an aircraft to either a satellite or land-based network. The service operates via a transceiver mounted in the aircraft on designated frequencies .
The earliest communication with aircraft was by visual signalling, ground-to-air only. Air-to-ground communication was first made possible by the development of two-way aerial telegraphy in 1912, soon followed by two-way radio. By the Second World War, radio had become the chief medium of air-to-ground and air-to-air communication. Since then ...
