GSR2700 IS Operations Manual 61
A
Ambiguity— The unknown integer number of cycles of the
reconstructed carrier phase. The carrier phase ambiguity is inherent
in an unbroken set of measurements from a single satellite pass at a
single receiver. Also known as integer ambiguity and integer bias.
Antenna— The antenna is the component of a GPS system that
collects the analog signal from the GPS satellite and sends this signal
to the GPS receiver for processing.
B
Base station— In differential positioning, a base station is the end of
the baseline that is assumed known and its position fixed. It is the
GPS receiver which is acting as the stationary reference. It has a
known position and transmits messages for the rover receiver, which
uses the information to calculate its position. Sometimes referred to
as a reference station.
Bluetooth— Wireless personal area network (PAN) standard that
enables data connections between electronic devices such as desktop
computers, wireless phones, electronic organizers, and printers in the
2.4 GHz range at 240 Kbps within a 30-foot range. Bluetooth depends
on mobile devices being equipped with a chip for sending and
receiving information.
C
C/A Code— See Coarse/Acquisition (C/A) Code .
Carrier phase— The phase of either the L1 or L2 carrier of a GPS
signal, measured by a receiver while locked onto the signal (also
known as integrated Doppler).
Circular Error Probable (CEP)— The radius of a circle, centered at
your true location, that contains 50% of the individual position
measurements made.
