RPIL:
RAIM Predict Ignore List. List of expected satellite
outages.
S
Second:
1/60th of a minute of a degree.
Seed Position:
A latitude and longitude position fix
approximately equal to the current position that the NMC
uses to determine the location of available satellites from
which signals may be received.
Selective Availability (SA):
The degradation of accuracy of
GPS position fix data by the United States Department of
Defense for civilian use.
SID:
Standard Instrument Departure: A predefined sequence
of waypoints used during departure procedures.
Space Vehicle (SV):
A GPS satellite.
STAR:
Standard Terminal Arrival Route. A predefined
sequence of waypoints used before arrival procedures.
Statute Mile:
A distance measurement equal to 5,280 feet or
0.87 of a nautical mile.
T
Terminal EPE:
Loran EPE limit of 1.7 nm.
Terminal Operations:
The phase of flight within 30 nm of the
departure airport or the destination airport when approach is not
enabled. During terminal operations, terminal RAIM integrity is
used. For Loran, terminal EPE applies.
Terminal RAIM Integrity:
1.0 nm RAIM alarm limit.
Three-dimensional (3D) Position Fix:
A position fix
defined by latitude, longitude, and altitude.
Track (TRK):
The imaginary line that the flight path of an
airplane makes over the earth.
Track Angle Error (TAE):
the absolute value of the DTK
minus the TRK.
TRU:
True outside air temperature.
True North:
Geographic north, at the earth’s north pole.
