01 - LabSat 2 Introduction

No headers

The LabSat 2 is a dedicated Global Navigation Satellite System (GNSS) signal generator with RF record and playback facilities, enabling real world GNSS RF testing to take place in the laboratory.  The LabSat is small and rugged, allowing it to be used in the field to continuously record the Global Positioning System (GPS), Galileo, BeiDou Navigation Satellite System (BDS) and GLONASS RF signals in a digital form which can then be replayed at a later date.

 

LabSat 2 is ideal for almost any kind of GNSS development, e.g. GPS/Galileo/BDS/GLONASS engines, GNSS enabled Smartphones, Portable Navigation Devices (PND), tracking systems and much more.  It is also very well suited to production line testing as it can represent a real world test as well as a carefully simulated scenario.

 

LabSat 2 works with the GPS/Galileo L1 (1575.42MHz) signal, BDS B1 (1561.098 MHz) signal  and GLONASS L1 (Channels 06 to -7 or approximately 1606MHz down to 1598MHz) signal and has no limit to the number of satellites that can be logged.

 

In addition to recorded data, the Labsat 2 can replay simulated, GPS L1 and or GLONASS L1 scenarios generated using the optional Racelogic SatGen v2 software.

 

Real world GNSS effects can be seen in test scenarios

  • Multipath
  • Drop-outs
  • Tree coverage
  • Adverse terrain effects
  • Atmospheric effects

 

 

 

Ability to replay data allows repeatable testing of GNSS receiver capabilities such as:

  • Sensitivity – Tracking and Acquisition
  • Time To First Fix (TTFF) – Cold, Warm and Hot Start
  • Position Accuracy and Repeatability
  • Tracking Accuracy and Repeatability
  • Reacquisition Time
