01 - LabSat3W Introduction
LabSat 3 Wideband is an RF signal record and replay system with 3 independently tuneable wideband channels. This
allows capture and replay of most GNSS signals and even a few non-GNSS signals. The three RF channels all share a
common sample rate which can be adjusted from 10 - 60 MHz.
Quantisation of I and Q signals is selectable from 1, 2 or 3 bits per signal. Depending on the combination of channel
bandwidth and quantisation, LabSat 3 Wideband will adjust the number of available RF channels to keep the record data
bandwidth within a rate that ensures continuous file transfer.
Because wideband recording allows capture of multiple GNSS frequencies within each RF channel, the procedure for
configuring LabSat 3 Wideband involves selecting the frequency bands most suitable for capture of the required GNSS
signals. LabSat helps by displaying only the frequencies for GNSS bands appropriate for the selected bandwidth.
Despite its simplicity, LabSat 3 Wideband supports a number of powerful features for use in industries such as
automotive, sports and aerospace including three RF channels for multiple constellation testing, dual CAN Bus
recording, inertial sensor logging and battery powered operation.

How does it work?
GNSS stands for Global Navigation Satellite Systems and is a general term that covers satellite positioning
constellations belonging to different countries around the world. These include, among others, the United States ‘GPS’,
the Russian ‘GLONASS’ and the Chinese ‘BeiDou’ systems. LabSat 3 Wideband is capable of recording and replaying
the raw radio signals that are transmitted by the various constellations of satellites. LabSat receives the signal from an
antenna just like a standard GNSS receiver but instead of processing each of the received signals to calculate a position
fix, LabSat 3 Wideband samples and stores the antenna signal at very high speed.
When recorded RF signal is replayed by LabSat 3 Wideband into a standard GNSS receiver, such as a portable
navigation system, the receiver will accept the signal as live, including all the velocity, delays and multipath effects.
This makes LabSat 3 Wideband invaluable for recording dynamic scenarios such as driving through a city in a vehicle.
The benefits of using a recorded test signal are consistency and reliability. For example, if testing of a product involves

going for a drive each time the receiver firmware is updated, the satellite positions and atmospheric conditions will all be
different for every drive. If the drive is recorded once with LabSat 3 Wideband, the recorded signal can be replayed over
and over on the bench saving hours of drive time and with the knowledge that conditions will be the same for each reply.
Registration
Racelogic recommend that all LabSat devices are registered immediately on receipt. Please go to www.labsat.co.uk/
register and fill in all the details requested. If you register your LabSat within its first year warranty, you will
automatically receive an additional year's warranty.
Registering your LabSat will enable you to easily communicate with our support team. Any firmware / software updates
will be available on the LabSat website. Updates are more robust and easier to use, and later firmware releases offer
bug fixes as well as added features and improvements to the original specification of the product. Your details will be
available to our Support Team, in case you need any assistance in the future.

Briefly press the power button to power up LabSat 3 Wideband. Connect from the RF output on the rear of LabSat 3
Wideband to your GPS system antenna input. Use the 'UP/DOWN' arrows to select a file. Press the 'PLAY' button to
start replay.

LabSat 3 Wideband contains an on board GNSS receiver that allows monitoring of the RF signals during record or
replay. To show a live histogram of satellite signal levels detected by the on board receiver, press the 'OK' button during
replay. Press the 'OK' button again to return to the replay status display. During replay, pressing the 'PLAY' button will
halt replay and return to the file list.
Record xample

To record a new file, connect the LabSat 3 Wideband antenna to the RF input on the rear of the LabSat. nsure that the
antenna has a clear view of the sky, press the 'REC' button to start recording. Press the 'REC' button again to stop
recording. While recording, if the SSD becomes full, recording will stop automatically. During recording, pressing
the 'OK' button will switch the display to show a live histogram view of the satellite levels being received by the on-board
GNSS monitor. Pressing the 'OK' button again will return to the record status display.

During recording, while using battery power, the GNSS monitor display will automatically revert to the record display
after a short period to conserve battery power. This power save feature can be switched off but it is recommended to be
left active for maximum battery life.

02 - LabSat3W Components
LabSat 3 Wideband has been designed to be portable and simple to use allowing virtually anyone to gather field test
signals without in depth training. Recording GNSS signals is as simple as positioning the antenna and pressing one
button. The sunlight-readable graphic display gives instant feedback of record status and can show live histogram data
to verify satellites in view during recording. Back at the Lab, recorded signals can be replayed at the push of a button for
repeatable, reliable testing.

LabSat 3 Wideband file formats
LabSat 3 Wideband uses a Linux XT4 formatted drive for data storage. Recorded data consists of two separate files
with the same name but with different extensions. The RF signal data is stored with the extension '.LS3W' and is a raw
binary file. The configuration used to record and replay the RF data is stored in the '.ini' file. When copying files to or
from the Labsat 3 Wideband SSD, both the '.LS3W' and '.ini' files must be copied together.
LabSat 3 Wideband SD Card
The 4 GB SD card included with the LabSat 3 Wideband system is used for firmware upgrades and includes the
following:
• SatGen simulation software video
• LabSat 3 Wideband demonstration files description
• Quick Start pdf
LabSat 3 Wideband 1 TB Solid State Drive (SSD)
The LabSat 3 Wideband 1 TB SSD includes the following:
• LabSat 3 Wideband sample files:
◦ 1 x UK dynamic file - 20 mins
◦ 3 x UK static files - 20 mins each
◦ 1 x Korea static file - 20 mins
◦ 1 x India static file - 20 mins
LabSat 3 Wideband SSD Access
The 1 TB Solid State Drive is removable. To gain access to the LabSat 3 Wideband internal SSD the systems lid must
be removed. To remove the systems lid, the locking pin at the rear must be depressed while the lid is push back towards
the catch. The SSD can then be removed by gently lifting the attached tag.
