01 - LabSat Introduction

The LabSat is a dedicated Global Navigation Satellite System (GNSS) signal simulator with RF record and playback facilities, enabling real world GPS & Galileo 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 RF GPS/Galileo signal in a digital form which can then be replayed at a later date.
 

LabSat is ideal for almost any kind of GPS development, e.g. GPS engines; GPS enabled Smartphones, Portable Navigation Devices, GPS 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.
 

To cover all testing requirements, replay scenarios can also be generated directly using the Racelogic SatGen software.  LabSat works with the L1 (1575.42MHz) signal and has no limit to the number of satellites that can be logged. Galileo L1 Signal can be recorded and replayed.

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
