Page 4: Introduction
If the drive is recorded once with LabSat 3, the recorded signal can be replayed over and over on the bench saving hours of drive time and with the knowledge that the conditions will be the same for each replay. -
Page 5: Components
Components LabSat 3 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. -

LabSat 3 file formats LabSat 3 uses I&Q binary data and runs the FAT32 file format. LabSat 3 files are recorded into a folder with separate 2GB data files which will run sequentially when replayed. The folder description GPS_000 will contain several files with the name format GPS_000_000.ls3. -
Page 7: Quick Start Guide
Quick start guide In addition to this guide, a short LabSat 3 Quick Start video is available on the LabSat 3 SD card and also on the LabSat 3 HDD. Example of Replay - using the included SD card with preloaded scenario. -

→ Power Save – When selected, will power down display backlight and internal monitor during recording. → CLK REF → Internal - As the default setting LabSat 3 will use it internal reference clock. → External 10MHz – Allows the user to connect a 10MHz reference signal on the REF input. -
Page 9: Replay Operation In Detail
Replay operation in detail LabSat 3 uses SD card or HDD memory for storage and playback of GNSS data. It is important to note that Class 10 or higher cards must be used to sustain the transfer speeds required. Racelogic recommend SanDisk Extreme Class 10 cards for best performance. -
Page 10: Record Operation In Detail
BeiDou B1 Depending on the model, LabSat 3 will have 1, 2 or 3 RF channels. This allows recording of 1, 2 or 3 frequency bands so, for example, a 2 constellation LabSat 3 may record the band containing GPS L1/Galileo E1 and the band containing GLONASS L1 simultaneously. -
Page 11: Navigating The Labsat Hdd File Layout
Navigating the LabSat HDD file layout Below is a guide to how the folder layout works on LabSat 3. This example below shows the folder layout on the HDD provided with LabSat 3. The LabSat USB HDD is uses multiple folders. When folders are detected LabSat will display them in a similar fashion to a PC using the DIR indicator. -
Page 12: Battery Operation And Charging
Alternatively, an external battery charger is available to order. To remove the battery from LabSat 3, unscrew the battery plate on the rear of the device and slide the battery out. When operating from battery power, the battery charge status will be shown in the top-right section of the display . -
Page 13: Battery Fitting, Removal And Handling
Battery fitting, removal and handling → Replace battery with Racelogic, Part No. RLACS201 only. Use of another battery may present a risk of fire, explosion or other malfunction. → Caution: The battery used in this device may present a fire or chemical burn hazard if mistreated. Do not disassemble or heat above 100°C (212°F) or incinerate. -
Page 14: External Reference Clock Input
RF data; the maximum input frequency for each channel is 1MHz. To record 2 digital channels, at least 2 RF channels must be selected or 1 single channel with 2-bit quantisation. The Digital menu allows CH1 or CH2 (subject to LabSat variant) to be configured to record any of the following parameters:-... -
Page 15: Expansion Connector
Expansion connector The EXPANSION connector on the rear of LabSat 3 gives access to a number of signals including CAN Bus, RS232, 1PPS & Digital input/output. Accessory RLACS202 is used to provide user signal access for integration into the users test system. Pin functions are as follows:-... -
Page 16: Can Bus
LabSat 3 is capable of listening to, and recording data from, two separate CAN networks. Dual channel CAN Bus data recording with LabSat 3 can be achieved in two ways. Depending on the mode selected, the CAN signal will be either digitized and re-created on a raw bit level or decoded and recorded in a time-stamped text file. -
Page 17: Filtering Can Frames
The log file is recorded in the same folder as the RF data and has a .TXT file extension. During recording, the CAN controller listens to the CAN bus and stores incoming data. LabSat 3 will transmit acknowledge pulses on the bus in response to correctly received data unless the ‘Silent Record’ option is ticked. -

Page 20: Converting Labsat Scenarios
LabSat uses a binary Intermediate Frequency, to down convert GPS RF data into a binary file, whereas LabSat 2 & 3 store GNSS RF data as an I & Q binary file. This means that existing LabSat scenarios cannot be run natively on a LabSat 2 or vice versa. -
Page 21: Recommended Media
When the upgrade has been completed the upgrade file will be erased from the SD card. If the upgrade fails for any reason the upgrade file will remain on the SD card and the LabSat 3 retains the previous version of firmware. -
