Section 1: Overview

1 Overview

The Intuicom Wireless RTK Bridge - Cellular expands access to GNSS network RTK

corrections for rover users in the field. The RTK Bridge - Cellular combines an embedded GPS

and cellular (CDMA or GSM/GPRS/EDGE) Internet connectivity with an Intuicom Wireless

Data Radio with to support a wide range of deployment configurations.

1.1 Key Features

•Connect to the Internet using a choice of either an embedded CDMA or

GSM/GPRS/EDGE cellular modem

•Connect to NTRIP Casters and stream any data/messages/corrections, etc.

•Connect to Raw/Dedicated TCP Sockets (non NTRIP)

•Embedded GPS can provide unit’s position to the GNSS network server for

individualized corrections or virtual reference station creation. Optionally enter a

user supplied fixed location or passthrough GGA messages from an external source

•All correction messages received are available on a front panel serial port for

connection directly to a GNSS rover, or to a third party radio for rebroadcast.

•Unit can provide authentication messages for Leica Spider ($GPUID) GNSS server

•Compatible with Intuicom 1200 Data Link radios for easy Leica System 900 and

1200 integration, as well as Intuicom Communicator and Communicator II, radios in

both Point-to-Multipoint and TDMA modes

•Compatible with Intuicom wireless data repeaters to extend wireless coverage area

•Store up to four configuration sets called “PROFILES” that can be selected for use in

the field without a PC– a PROFILE contains configuration data such as GNSS server

IP, port, username, password, mountpoint, static location, front panel baud rate, etc.

Figure 1-2: Intuicom Wireless RTK Bridge - Cellular Architecture Overview

Typical Application - The Intuicom Wireless RTK Bridge has a flexible configuration

and can be used to satisfy a range of connectivity needs. Typical installations have the

RTK Bridge configured to connect to an NTRIP Caster where it provides mountpoint and

authentication information. Once connected to a mountpoint, it will stream its GPS point

position (from its internal L1 GPS) allowing the Network Correction Server (such as

Leica Spider) to generate individualized corrections or create a virtual reference station.

The unit receives these corrections via IP and then broadcasts them to receiving RTK

rover units.

Leveraging Existing Data Radios - The Intuicom Wireless RTK Bridge can be used to

supplement and existing wireless network, replacing the local base station GPS. Users

simply connect a third party base radio to the Data Out port on the front of the unit to

broadcast a copy of the correction stream. If no rover RTK users are utilizing Intuicom

Wireless Data Radios, the internal radio can be disabled to conserve power.

RTK Corrections

Figure 1-4: RTK Bridge Extending Carrier Data Network

Extending CDMA/GSM Data Service Reach – In this example, rovers are operating in an area

not directly covered by CDMA/GSM cellular data service. The rovers however are still within

the network of GNSS reference stations and thus can benefit from a network correction. Using a

high gain antenna on the CDMA/GSM cellular modem, a reliable connection can be established

allowing the RTK Bridge to connect to the Internet and the GNSS network server. Corrections

are streamed from the GNSS network server to the RTK Bridge where they are broadcast over an

Intuicom Wireless Data Network to all RTK rovers. In this case the rovers are utilizing Intuicom

1200 Data Link radios to receive the correction messages. Note that in this application, any

number of Rover users can receive the same correction messages broadcast from the RTK

Bridge. Furthermore, if the distance between the RTK Bridge and the rover users is great – the

RTK Bridge can be configured to report its position to the GNSS Network server as if it were in

the location of the rovers – further optimizing the network correction generated by the GNSS

network server.

Section 2: Initialization and Configuration

2 Initialization and Configuration

Prior to the first use of the Intuicom RTK Bridge must be activated and configured. A onetime

process of activation is required to setup the integrated CDMA or GSM cellular modem for use

on the chosen carrier’s network. For the device to connect to the current GNSS Network server,

further configuration is required. The unit can store up to four configuration sets called Profiles.

In the field, the current Profile can be changed without the need of a PC. Profiles enable the user

to do things like change NTRIP mountpoints, change GNSS servers, change how locations sent

to the server, etc. At least one Profile must be configured.

2.1 Accessing the Configuration Menu

All configuration and initialization is performed by accessing the configuration menu on the

RTK Bridge with a PC using a terminal emulation program (such as HyperTerminal,

ProComm, TerraTerm, or Minicom), an available serial port, the power/data cable, the RTK

Bridge itself, and the power adapter for the RTK Bridge.

Figure 2-1: Cable Connections for Accessing Configuration Menu

To access the RTK Bridge configuration menu use the following steps:

1. Connect the Lemo end of the power/data cable to the CONFIG port of the RTK

Bridge, and the DB9 connector to an available DB9 COM port on the PC to be used

for configuration. If no COM port is available, a USB-COM port adapter may be

used. Attach the AC power adapter to the power connector on the power/data cable

and plug the AC adapter into an outlet.
