Glossary
This section defines technical terms and abbreviations used in this
manual. It includes terms from the field of GPS technology.
2-D GPS mode
A procedure of determining a 2-D position using signals
received from the best (or only) three available GPS
satellites. Altitude is assumed to be known and constant. A
2-D position solution will only be determined if signals from
three or more satellites are available.
2 dRMS
Twice the distance root mean squared. The error distance
within which 95% of the position solutions will fall.
3-D
Three Dimensional. A 3-D position is defined as latitude,
longitude, and altitude.
2-D
Two Dimensional. A 2-D position is defined as latitude,
longitude, and altitude.
3-D GPS mode
A procedure of determining a 3-D position using signals
received from the best (or only) four available GPS satellites.
A 3-D position solution will only be determined if signals
from four or more satellites are available.
almanac
A reduced-precision subset of the ephemeris parameters.
Used by the receiver to compute the elevation angle, azimuth
angle, and estimated Doppler of the satellites. Each satellite
broadcasts the almanac for all the satellites in the system.
ASCII
American Standard Code for Information Interchange. A
standard set of 128 characters, symbols and control codes
used for computer communications. ASCII characters require
7 bits of data to send, but are often sent 8 bits at a time with
the extra bit being a zero.
