N
Network Real Time Kinematic (RTK)—a satellite navigation technique used to enhance the
precision of position data derived from satellite-based positioning systems such as GPS,
GLONASS, Galileo and BeiDou systems.
O
Option Authorization File (OAF)—This enables the specific features that a customer purchases.
P
Phase Center of Antenna—The point from which the electromagnetic radiation spreads spherically
outward, with the phase of the signal being equal at any point on the sphere.
Pocket 3D—Field controller software (made by Topcon) that supports both GNSS and Total Station
measurements.
R
Real Time Kinematic (RTK)—A precise method of real-time surveying. RTK enables you to check
the measurement quality without having to process the data.
Rover—A mobile GNSS receiver and data collector used for determining field location.
S
Satellite Based Augmentation Systems (SBAS)—SBAS transmits differential corrections and
messages for navigation satellites that are within sight of a network or a reference station in a wide
area—such as a continent.
Static Survey—Typically uses a network or multiple baseline for positioning. The static survey
method provides the highest accuracy and requires the longest observation times.
T
Topcon Receiver Utility (TRU)—Hardware configuration software designed for GNSS receivers and
peripheral devices. TRU software is normally included on the GPS+ Software CD that accompanied
your receiver.
U
Universal Serial Bus (USB)—An industry connection standard used by devices, such as a receiver,
or controller to connect to a computer.
