Azimuth (AZ)
Given in degrees. It concerns the position of a satellite relative to the South, assuming that the magnetic south, marked by the Meridian 0, says Greenwich is 0 °. By extension, the term refers to the antenna mount, allowing the dish to move in horizontal planes (azimuth) and vertical (elevation or site).
Astra
Names of satellites operated by SES (Societe Europeenne des Satellites), headquartered in Betzdorf, Luxembourg. No fewer than eight satellites are currently’co-located’ at 19.2 degrees East, combining analog and digital broadcast. SES operates a second orbital position at 28.2 degrees East, for the UK market.
ATM
English abbreviation for Asynchronous Transfer Mode. Communication protocol for high speed, creates for the transport of data and multimedia information (video, sound).
Mitigation
Expressed in decibels (dB), the opposite of gain, contrast ratio of the Hughes Satellite Internet input (voltage or current) and output in an electronic circuit or the extent of weakening of signal. The attenuation or weakening of an satellite Internet optical fiber is measured in dB per unit length (0 dB = no attenuation).
Auto-Focus (or Auto-Tracking)
Expression of English origin. Device allowing an HughesNet antenna to remain pointed at a satellite automatically, without having to make successive adjustments and adjustments, due to the change of position in the sky or the possible movement of the antenna. The most sophisticated can be used on ships or certain moving vehicles. The literal translation would be’auto tracking’.
