Record & replay more GNSS signals than ever before

The LabSat 3 Wideband is Racelogic's most powerful LabSat yet. Now you can record and replay more GNSS signals at much higher resolution than ever before.

With three channels, a bandwidth of up to 56 MHz and 6 bit sampling (3 bit I & 3 bit Q), LabSat 3 Wideband can handle almost any combination of constellation and signal that exists today, with plenty of spare capacity for future planned signals.

Small, battery powered and with a removable solid state disk, LabSat 3 Wideband allows you to quickly gather detailed, real world satellite data and replay these signals on your bench.

 

LabSat 3 Wideband can record and replay the following signals:

  • GPS: L1 / L2 / L5
  • GLONASS: L1 / L2 / L3
  • BeiDou: B1 / B2 / B3
  • QZSS: L1 / L2 / L5
  • Galileo: E1 / E5a / E5b / E6

LabSat 3 Wideband in Detail

This is where you'll find answers to the most commonly asked LabSat 3 Wideband questions. If you require further assistance please don't hesitate to contact us or visit the Support area of the website.

How easy is LabSat 3 Wideband to configure?

To simplify the configuration and device control process, LabSat 3 Wideband has an internal web server for configuration which can be easily accessed via a standard web browser on your PC.

The image below shows an example test setup within the LabSat 3 Wideband web server. All GNSS signals and three signal bands are selected, a bandwidth of 56 MHz and a current quantisation of 1.

What are the Bandwidth, Frequency & Quantisation settings?

Bandwidth Setting

LabSat 3 Wideband has three bandwidth settings. 56 MHz, 30 MHz and 10 MHz.

The bandwidth of the GNSS signals varies, for example a GPS L1 C/A code signal has a bandwidth of 24 MHz. However, due to the signal design a bandwidth of 9.66 MHz will capture enough data to allow the receiver under test to acquire, track and navigate as with LabSat 3 single, dual and triple constellation devices.

Other signals with a different signal design like Galileo E1 PRS signal has a bandwidth of 46 MHz and a signal design spread across the bandwidth.

Many other signals have a similar requirement like GPS L1/L2 P code and M code. LabSat 3 Wideband has been designed to capture all these signals.


Frequency Setting

LabSat 3 Wideband is designed to capture and replay GNSS signals in the upper L-Band (1559 - 1610 MHz) and lower L-Band (1164 - 1300 MHz).


Quantisation Setting

LabSat 3 Wideband can record and replay GNSS Signals at quantisation levels of:

  • 3 bits (3 bit I + 3 bit Q)
  • 2 bits (2 bit I + 2 bit Q)
  • 1 bits (1 bit I + 1 bit Q)
What additional signals can I record & replay ?

LabSat 3 Wideband can record a range of additional signals, synchronised to the GNSS input: dual-CAN, RS232, and digital inputs are simultaneously captured increasing the level of playback realism and allowing for a wider range of testing.

This flexibility means that the development of products incorporating this variety of signal streams can be conducted with absolute convenience on the bench, without the need for costly and time consuming field trials. NMEA data is also recorded via the inbuilt GNSS receiver.

Can I test a device with an internal antenna and no external connector?

You can test a device with an internal antenna and no external connector by using an active GPS antenna or the Passive GPS/GLONASS antennas. These antennas connect directly to the RF ports on the LabSat 3 Wideband and will transmit the RF signal over short distances to the GNSS device being tested.

You will however need to be in an RF-screened environment to avoid interference with live signals. This can be done in a fully screened RF room or a portable enclosure, such as the LabSat Test Enclosure. This allows for secure screened testing and is ideal when working with devices that do not have an external antenna connector - such as wearables, smartphones, and sports/fitness trackers.
