A transmission frequency of 2390 megahertz was selected, as this was the planned frequency band for future satellite experiments. East-to-west transmissions were sent from Crawford Hill using a 18 m (59 ft) diameter parabolic antenna and received at Goldstone using the existing Pioneer program antenna.
After KABC lost its signal transmission, the station provided digital streams of its morning newscasts directly to cable and satellite TV operators, Disney-owned Hulu Live TV and other streaming apps.
A Sun outage, Sun transit, or Sun fade is an interruption in or distortion of geostationary satellite signals caused by interference (background noise) of the Sun when it falls directly behind a satellite which an Earth station is trying to receive data from or transmit data to. It usually occurs briefly to such satellites twice per year and ...
The forerunner of the DSN was established in January 1958, when JPL, then under contract to the U.S. Army, deployed portable radio tracking stations in Nigeria, Singapore, and California to receive telemetry and plot the orbit of the Army-launched Explorer 1, the first successful U.S. satellite.

Patrols noticed water “bubbling up in the adjacent farmland” at 11 p.m., the first sign there was a problem. Pajaro, a farming town of about 3,000 residents, saw hundreds displaced by flooding ...
As four fires grew in Southern California, new satellite images show their scale and the amount of smoke pouring east. The Line, Bridge, Airport and Roblar fires , all of which began in the past ...
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military ...
