  2. AN/FPS-16 Instrumentation Radar - Wikipedia

    en.wikipedia.org/wiki/AN/FPS-16_Instrumentation...

    The accuracy of Radar Set AN/FPS-16 is such that the position data obtained from point-source targets has azimuth and elevation angular errors of less than 0.1 milliradian (approximately 0.006 degree) and range errors of less than 5 yards (5 m) with a signal-to-noise ratio of 20 decibels or greater.

  3. Horizontal coordinate system - Wikipedia

    en.wikipedia.org/wiki/Horizontal_coordinate_system

    Azimuth is measured eastward from the north point (sometimes from the south point) of the horizon; altitude is the angle above the horizon. The horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane to define two angles of a spherical coordinate system : altitude and azimuth .

  4. Direction finding - Wikipedia

    en.wikipedia.org/wiki/Direction_finding

    The DF receiver enjoys a detection range advantage [35] over that of the radar receiver. This is because the signal strength at the DF receiver, due to a radar transmission, is proportional to 1/R 2 whereas that at the radar receiver from the reflected return is proportional to σ/R 4 , where R is the range and σ is the radar cross-section of ...

  5. Azimuth - Wikipedia

    en.wikipedia.org/wiki/Azimuth

    The azimuth is the angle formed between a reference direction (in this example north) and a line from the observer to a point of interest projected on the same plane as the reference direction orthogonal to the zenith. An azimuth (/ ˈ æ z ə m ə θ / ⓘ; from Arabic: اَلسُّمُوت, romanized: as-sumūt, lit.

  6. Bearing (navigation) - Wikipedia

    en.wikipedia.org/wiki/Bearing_(navigation)

    In satellite broadcasting, a bearing is the combination of antenna azimuth and elevation required to point (aim) a satellite dish antenna in a given direction. The bearing for geostationary satellites is constant. The bearing for polar-orbiting satellites varies continuously.

  9. DirecTV satellite fleet - Wikipedia

    en.wikipedia.org/wiki/DirecTV_satellite_fleet

    The DirecTV satellite fleet is a group of communications satellites located at various geostationary orbits that DirecTV uses for their satellite television service and HughesNet (formerly known as DirecWAY and DirecPC) internet service. The "DirecTV" prefix in their names has been changed to "T".
