5.1 Definitions
GPS/GNSS
GNSS stands for Global Navigation Satellite System. GNSS
covers all the different satellite
systems in use worldwide, such as GPS (USA), GLONASS
(Russia), Galileo (Europe), Beidou (China).
RTK
(Real time kinematic)
RTK (Real-Time Kinematic) positioning is a method used by
an RTK-enabled GNSS receiver (called a Rover, in this case
the RD8200SG) to obtain extremely precise positions by
using data from an RTK base station that is transmitted over
the internet (NTRIP).
NTRIP
NTRIP stands for Networked Transport of RTCM via Internet
Protocol. The NTRIP protocol enables the mobile GNSS
receiver (RD8200SG) to access data from the RTK base
station over the internet to achieve high accuracy. NTRIP
can be built in the structure of a mapping app or it can be a
separate mobile app.
