Selecting a DGPS Mode
Introduction
MobileMapper CX can be operated in one of the following
DGPS modes:
1.
SBAS
: Differential corrections from SBAS satellites
(SBAS) are received by MobileMapper CX itself through
one of its GPS reception channels. This is the most
straightforward technique to implement DGPS in
MobileMapper CX.
IMPORTANT!
SBAS is the only real-time DGPS mode that
can be used simultaneously with raw data recording.
2.
Beacon
: Differential corrections are received by the belt-
carried Magellan MobileMapper beacon. This unit is con-
nected to the MobileMapper CX via Bluetooth or a serial
cable.
3.
Direct IP
: Differential corrections are taken from the Inter-
net at a fixed IP address. They are routed to MobileMap-
per CX via a GSM/GPRS cell phone and Bluetooth.
4.
NTRIP
(=Networked Transport of RTCM via Internet Proto-
col): Same as Direct IP except that the provider uses the
NTRIP protocol to deliver its differential corrections.
5.
Other RTCM Source
: Differential corrections are received by
third-equipment delivering RTCM2.x message type #1.
This third equipment is connected to MobileMapper CX
via a serial cable or Bluetooth.
The table below summarizes the connection and identification
data needed when operating in the NTRIP or Direct IP mode.
