A Viewsat Xtreme FTA receiver. A free-to-air or FTA Receiver is a satellite television receiver designed to receive unencrypted broadcasts. Modern decoders are typically compliant with the MPEG-2/DVB-S and more recently the MPEG-4/DVB-S2 standard for digital television, while older FTA receivers relied on analog satellite transmissions which have declined rapidly in recent years.
Universal Satellites Automatic Location System (USALS), also known (unofficially) as DiSEqC 1.3, Go X or Go to XX is a satellite dish motor protocol that automatically creates a list of available satellite positions in a motorised satellite dish setup. It is used in conjunction with the DiSEqC 1.2 protocol. It was developed by STAB, an Italian ...
TrackSat - Satellite tracker – can track satellites orbiting the Earth in real time and predict their passes over your specific geolocation. Includes satellites such as International Space Station (ISS), Starlink, SpaceX Crew Dragon, Terra, NOAA and many others.
Free-to-air (FTA) services are television (TV) and radio services broadcast in unencrypted form, allowing any person with the appropriate receiving equipment to receive the signal and view or listen to the content without requiring a subscription, other ongoing cost, or one-off fee (e.g., pay-per-view). In the traditional sense, this is carried ...
As of July 2023, the website UCS Satellite Database lists 6,718 known satellites. Of these, 580 are listed in the database as being at GEO. The website provides a spreadsheet containing details of all the satellites, which can be downloaded. Listings are from west to east (decreasing longitude in the Western Hemisphere and increasing longitude ...
The second time LOP is an identical measurement using a different secondary satellite, or using the same secondary satellite, but later in time. Similarly, two frequency LOPs can be used to determine a location. It can be shown that, in general, it is expected that the two LOPs intersect in two places.
A satellite minidish. This is a list of the free-to-air channels that are currently available via satellite from SES Astra satellites (Astra 2E/2F/2G) at orbital position 28.2 °E, serving Ireland and the United Kingdom. Sky and Freesat use these satellites to deliver their channels. If one was to change providers between Sky and Freesat, one ...
Pseudorange. The pseudorange (from pseudo- and range) is the pseudo distance between a satellite and a navigation satellite receiver (see GNSS positioning calculation), for instance Global Positioning System (GPS) receivers. To determine its position, a satellite navigation receiver will determine the ranges to (at least) four satellites as ...
