Tallysman TW5382 Smart GNSS Antenna for High Accuracy Timing

Tallysman TW5382 Smart GNSS Antenna for High Accuracy Timing

The TW5382 GNSS smart antenna is a multi-band (L1/L2), multi-constellation integrated GNSS receiver and precision timing reference antenna.



The TW5382 GNSS smart antenna 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 demanding infrastructure applications.

The TW5382 incorporates a latest generation multi-band (L1/L2) GNSS receiver with a Tallysman AccutennaTM 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 the most effective method for the removal of ionospheric error.

Combined with the dual feed AccutennaTM, which greatly improves the rejection of multi-path signal interference, the TW5382 offers exceptional performance to meet the most stringent 5G timing requirements, significantly reducing the time error of the primary source of cellular network synchronization.

The TW5382 is designed to meet the strictest timing synchronization requirements 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 precise and reliable solution which is unaffected by ionospheric errors, and provides resilience to jamming.

The TW5382 timing module’s multi-band (L1/L2) capability reduces the timing error under clear skies to less than 5ns without the need for an 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 2.5ns.
