LabSat 4 is shipped with a rechargeable, lithium-ion smart battery pack. A fully charged battery provides a unit operation time of a minimum of 1 hour. You can charge the battery by connecting an external power source to the Power port on LabSat 4. 

You can read more about the battery pack, including operation, charging, fitting, removal and handling, here.

You can apply power to LabSat 4 via mains power with the power supply (RLVBACS020) or from the vehicle via the cigar plug to power (RLCAB010LE) cable. When you power LabSat 4 from an external source, it will automatically charge the internal battery pack, and seamlessly switch to battery operation when the external power is removed.

LabSat 4 comes supplied with a GNSS antenna with magnetic mounting (RLACS354). The antenna is an active device with approximately 37 dB of gain. LabSat 4 provides a 4 to 4.5 V DC bias for antenna power on the centre pin of the RF IN connector. You can also use third-party antennas, providing they are compatible with the 4 to 4.5 V bias. 

If you connect LabSat 4 to an antenna that requires a higher bias voltage (e.g. 12 V), you must supply the antenna bias and insert an appropriate DC block at the RF IN connector to avoid damaging LabSat 4. You can read more about using higher bias voltage antennas here.  

LabSat 4 uses different media types for different operations:

LabSat 4 records scenario files to and replays scenario files from the internal SSD. 

You can read more about the compatible media for LabSat 4 here.

LabSat 4 has a Host USB port that you can use to connect a USB storage device.

This USB device can be used to record and replay scenario files and to transfer files to and from the internal SSD. 

You can also connect to and use Network File Systems (NFS), such as Windows File Explorer to access and manage your files and high-speed Network Attached Storage (NAS) devices to replay from.  

The 8 GB SD card that is included with LabSat 4 can be used for firmware upgrades and to transfer files to and from the internal SSD. You cannot use it to record/replay scenario files.
 

LabSat 4 has a complex array of settings for both GNSS signal and external data recording. To simplify the configuration and device control process, LabSat 4 has an internal web server that you can easily access via Ethernet and a standard internet web browser.

You can read more about the LabSat 4 Web Server, how to connect to it and how to use it here.

LabSat 4_Histogram  (v1.0 RE 23MAY2024)

LabSat 4 features a multi-constellation GNSS receiver that you can use to monitor L1 band GNSS signals in the incoming RF signal during a recording or the outgoing RF signal during a replay. The USB device connector on the rear panel of LabSat 4 functions as a virtual serial connection and will output NMEA data from the GNSS monitor at 115_200 baud when it is recording or replaying.

In addition to this, you can press the OK button when the unit is recording or replaying to switch the display to show satellite tracking levels for GPS L1, GLONASS L1, Beidou B1 and Galileo E1 satellites. Press the Up and Down arrows while in this display will swap between constellations.

During recording, the primary aim of the GNSS monitor is to give an indication when an L1 band GNSS antenna is connected and working.

During replay, the GNSS monitor will listen to the RF output signal. If the replayed signal contains valid L1 GNSS signals, these will be reported by the monitor.
