TW5382 Smart GNSS Antenna for High Accuracy Timing

The TW5382 is a multi-band (L1/L2), multi-constellation integrated GNSS receiver and precision timing reference antenna. The TW5382 is capable of providing nanosecond-level timing accuracy to support the most demandinginfrastructure applications.    

Interference Resilience
The TW5384 incorporates a latest generation multi-band (L1/ L2) GNSS receiver with a Tallysman Accutenna® multi-band (L1/L2) dual feed patch.  The state of the art  GNSS receiver supports concurrent tracking of all four major constellations (GPS, BeiDou, Galileo and GLONASS ) in multiple frequency bands.  The multi-band (L1/L2) architecture is a highly effective method for the removal of  ionospheric error.  The TW5382 employs multi-stage filtering with low noise figure LNAs, combined with the dual feed Accutenna®, which greatly improves the rejection of multi-path signal interference, to offer exceptional performance to meet the most stringent timing applications.  

Precision Timing
The TW5382 is designed to meet the strictest timing synchronization applications in 5G mobile networks on a global scale.  The concurrent multi-band (L1/L2) access to all four satellite constellations improves the receiver’s capability to deliver a quick, precise and reliable solution which is unaffected by ionospheric errors, and improved resilience to jamming. 

The TW5382 timing module’s multi-band (L1/L2) capability reduces the timing error under clear skies to less than 5 ns without the need for external GNSS correction service.  

The TW5382 offers an optional master and slave configuration that features a differential timing mode that exchanges correction data with a neighboring TW5382 timing receiver via a RS-485 communication link.  Under optimal conditions the timing accuracy can be further improved to less than 2.5 ns.
