Ephemeris plural ephemerides
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.
ESD: Electro-Static Discharge
large momentary unwanted currents that cause damage to electronic equipment.
GPS: Global Positioning System
A space-based radio positioning system that provides accurate position, velocity, and time data.
LGA: Land Grid Array
A physical interface for microprocessors. There are no pins on the chip; in place of the pins are
pads of bare gold-plated copper that touch pins on the motherboard.
NMEA: National Marine Electronics Association
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.
SBAS: Satellite Based Augmentation System
Any system that uses a network of geostationary satellites and ground stations to improve the
performance of a Global Navigation Satellite System (GNSS). Current examples are EGNOS
and WAAS.
SiRFInstantFix
Eliminates the initial delay of obtaining GPS satellite location data from the satellites themselves
by using algorithms to predict seven days of satellite location data.
SiRFLoc
Allows a GPS receiver in a wireless device to intelligently switch between several different
modes, ranging from a stand alone mode through various aided modes to determine a position
based on the application and signal strength environment. This technology optimizes the use of
airtime and flexibility depending on the situation.
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.
