Elevation Mask
Elevation Mask is the minimum angle between a satellite and
the horizon for the receiver to use that satellite in the solution.
Satellites near the horizon often provide noisy signals and
should be avoided.
Firmware
Firmware is the software loaded into the receiver that controls
the functionality of the receiver and runs the GNSS engine.
GALILEO
Galileo is a global navigation satellite system implemented by
the European Union and European Space Agency. Global
coverage is available, and the full constellation is expected by
2020.
GAGAN
GPS Aided Geo Augmented Navigation is a satellite-based
augmentation system (SBAS) that provides free differential
corrections over satellite in India.
GLONASS
Global Orbiting Navigation Satellite System (GLONASS) is a
Global Navigation Satellite System (GLONASS) deployed,
and maintained, by Russia. It is comparable to the United
States’ GPS system.
GNSS
Global Navigation Satellite System (GNSS) is a system that
provides autonomous 3D position (latitude, longitude, and
altitude) along with very accurate timing globally by using
satellites. Current GNSS providers are: GPS, GLONASS and
Galileo. BeiDou is expected to have global coverage by 2020.
GPS
Global Positioning System (GPS) is a global navigation
satellite system implemented by the United States.
Heading
Heading is the angle between true north and the vector
calculated from the primary to secondary antenna.
Heading Bias
Heading Bias is an offset applied to the heading value the
receiver calculates.
Mountpoint
Mountpoints are the specified data streams in Ntrip. Multiple
base stations may send data to an Ntrip caster. Each base
station has a unique Mountpoint.
Multipath
Multipath occurs when the GNSS signal reaches the antenna
by two or more paths. This causes incorrect pseudo-range
measurements and leads to less precise GNSS solutions.
NMEA
National Marine Electronics Association (NMEA) is a marine
electronics organization that sets standards for
communication between marine electronics.
