or carrier phase measurement; ideally, the number of cycles of the carrier frequency of a specific GNSS signal between the phase center of the GNSS SV and the phase center of the user's antenna, [..]

"Earth-centered, Earth-fixed"

"Airborne Laser Scanning"; a lidar system installed in an aircraft that scans ground targets in a swath beneath the airborne aircraft; see National Center for Airborne Laser Mapping - NCA [..]

"Antarctic NETwork"; network of GNSS stations in or near Antarctica; see also POLENET

(for the GNSS community:) a resonant device that detects the GHz GNSS (GPS, GLONASS, Beidou/Compass, Galileo, QZSS, or SBAS) microwave signals and converts them to electrical signals for pro [..]

a 50-ohm impedence, RF-shielded, co-axial cable used to connect the antenna to the receiver

a thin, almost microwave-transparent material placed over a GNSS antenna, often in the shape (or nearly so) of a simple geometrical surface (e.g. hemisphere, cone, paraboloid, etc.); use of an ante [..]

vertical distance from the survey point of a monument to the antenna reference point (ARP) of the antenna; this may be calculated using the geometry of the antenna and the antenna slant height

the antenna is usually rotated into a standard orientation, often so that the antenna cable connector is toward geographic north, though often in the field only the local magnetic north direction i [..]

or ARP; an established point on the antenna choke ring, ground plane, or base from which the phase centers of the GNSS carrier waves are measured (e.g. L1, L2, and L5 for Navstar GPS); for specif [..]
