11.0 Glossary and acronyms
2dRMS:
twice-distance Root Mean Square
A horizontal measure of accuracy representing the radius of a circle within which the true value
lies at least 95% of the time.
Almanac
A set of orbital parameters that allows calculation of approximate GPS satellite positions and
velocities. The almanac is used by a GPS receiver to determine satellite visibility and as an aid
during acquisition of GPS satellite signals. The almanac is a subset of satellite ephemeris data
and is updated weekly by GPS Control.
C/A code:
Coarse Acquisition code
A spread spectrum direct sequence code that is used primarily by commercial GPS receivers to
determine the range to the transmitting GPS satellite.
CEP:
Circular Error Probable
The radius of a circle, centred at the user’s true location, that contains 50% or the individual
position measurements made using a particular navigation system.
EGNOS:
Euro Geostationary Navigation Overlay Service
The system of geostationary satellites and ground stations developed in Europe to improve the
position and time calculation performed by the GPS receiver.
Ephemeris
A set of satellite orbital parameters that is used by a GPS receiver to calculate precise GPS
satellite positions and velocities. The ephemeris is used to determine the navigation solution and
is updated frequently to maintain the accuracy of GPS receivers.
GPS:
Global Positioning System
A space-based radio positioning system that provides accurate position, velocity, and time data.
I/O:
Input/output
MIPS:
Millions of Instructions Per Second
OEM:
Original Equipment Manufacturer
Re-acquisition
The time taken for a position to be obtained after all satellites have been made invisible to the
receiver.
SEP:
Spherical Error Probable
The radius of a sphere, centred at the user’s true location, that contains 50% of the individual
three-dimensional position measurements made using a particular navigation system.
SRAM:
Static Random Access Memory
WAAS:
Wide Area Augmentation System
The system of satellites and ground stations developed by the FAA (Federal Aviation
Administration) that provides GPS signal corrections. WAAS satellite coverage is currently only
available in North America.
