TW5340 User Manual
1 Introduction
The TW5340 GNSS receiver/antenna incorporates the ST STA8088 state of the art
receiver which provides 32 high sensitivity tracking channels which can be assigned
to acquire and track GPS and GLONASS signals simultaneously. The TW5340 is
designed for use in professional grade applications such as precision timing, network
synchronization, low current battery and vehicle tracking applications.
The TW5340 family of GNSS receiver/antennas employs Tallysman’s Accutenna™ dual
feed antenna patch technology which greatly improves rejection of multi-path signals
across the whole GNSS band, resulting in much higher precision than single feed
antennas which are typically tuned to a single GNSS frequency.
The TW5340 supports ST Microelectronics Autonomous A-GPS which accelerates GPS
positioning by predicting satellite ephemeris data based on previous observations, this
results in extremely fast Time-To-First- Fix.
The TW5340 supports 3 modes of operation; Navigation, Standby and Low Current
(expert mode parameters only). A hardware interface is provided for external
application to control the Standby mode, this is especially useful in applications that
require low current drain.
The TW5340 outputs standard NMEA 0183 output with navigation updates rates up to
10Hz are supported. Three (3) messages lists can be output each with different output
rates.
The TW5340 is available with RS232, and CMOS interfaces and input voltage options of
3,3V, 5.0V and 12V.
A standard one pulse-per-second 1PPS output is available as a single ended output or as
a differential output at RS422 levels. The 1PPS can be configured to be synchronized to
UTC, GPS or GLONASS reference time.
Tallysman Windows™ based TW5340 Configurator application provides for simple
configuration of TW5340 parameters such as tracking, Standby mode operation, 1 PPS
timing, constellations, SBAS etc.

3 GNSS Systems
Tallysman TW5340 family of GNSS Receiver/Antennas are multi-GNSS receivers that
receive and track GPS, and GLONASS, signals simultaneously.
3.1 GPS
The US Global Position System (GPS) uses L1C/A signals at 1575.42 MHz to determine
position.
3.2 GLONASS
The Russian GLONASS satellite system is an alternative system to the US-based Global
Positioning System (GPS).

TW5340 User Manual
4 NMEA Packet Format
The TW5340 serial interface is based on the NMEA-0183 protocol standard.
The NMEA -0183 protocol starts with a “$” character followed by a NMEA Talker ID.
“GP” indicates Talker ID for the GPS constellation
“GL” indicates Talker ID the GLONASS constellation
“GN” indicates Talker ID for all constellations
5 Software Utilities
5.1 Open Source GPS Software Utilities
The following open source GPS utility can be used to display the GPS and GLONASS GGA
and GSV messages with Talker ID’s GP and GL.
http://www.visualgps.net/VisualGPSView/
Note: “GN”Talker ID’s are not currently supported by this application.
This VisualGPS application can log data which can subsequently be imported into the
following data conversion application for easy display tracking data on Goggle maps:

Note 1 :
TW5340 Hardware has been changed on Rev 3 to provide better noise immunity of the
1PPS outputs. The following pin changes were made:
1PPS B was pin 3 & is now pin 1
1PPS A was pin 4 & is now pin 2
Wake up input was pin 1 & is now 3
Fix Quality/Standby status was pin 2 & is now pin 4
Note 2:
There is no change in the Test Adaptor cable 27-0045-0
6.1 TW5340 Installation
For best results the TW5340 GPS Receiver/Antenna should installed with a clear view of
the sky. The GPS Receiver/Antenna will obtain a 3D fix GPS fix with a minimum of 4
satellites.
6.2 Testing
Tallysman TW5340 DB9 Test adaptor (part # 27-0045-1) connects to the RJ45 connector
on the TW5430 and provides a DB 9 COM port connection to a PC for testing purposes.
Figure 4 shows the test system set-up, connect the adaptor RED wire to the positive
supply and the Black wire to Gnd.
If the TW5340 outputs at RS232 levels the Test Adaptor can be plugged directly into the
PC Com Port, if the TW5340 outputs at CMOS levels a CMOS to RS232 converter will be
required between the Test Adaptor and the PC COM port.
Baud Rate
The default output from the TW5340 is 5 digit resolution GGA, GSV and Usage messages
at 115,200 baud. See section 10 for message format information.

Satellite Output Test
To display GPS/GLONASS satellite outputs the TW5340 must be configured to output a
GSV and GGA messages (default configuration). Run the VisualGPS application (see
section 5.1), select the Front Panel Status tab to display:

To read and write the TW5340 configuration parameters the same hardware test
configuration is can be used while running the Tallysman Windows based Configurator
application on the PC. See section 9 for configuration details.
The SBAS satellite is indicated by its NMEA ID and not the PRN #. See Table 5
for details.
6.3 Power
The TW5340 operates from 3.3V, 5V and 6to 16 volts. Overvoltage and transient
protection is provided making it suitable for installation in the harshest of vehicle
installations.
On the RJ45 connector shown in Figure 3:
Connect the BROWN wire on the TW5340 to Positive supply
Connect the BROWN/WHITE wire on the TW5340 to Gnd
6.4 1PPS
The TW5340 provides a one (1) pulse-per second output signal for timing purposes.
Differential 1PSS outputs are provided at RS422 levels.
