GPS timing receiver

Trimble Navigation has introduced an embedded GPS receiver for timing applications - the Resolution T receiver.

It enables system integrators to add precise GPS or Universal Time Coordinate time and synchronisation to many products where cost or size had previously been a limitation. The small, 3.3 V receiver enables integrators to embed precise GPS timing in their actual application.

Features of the receiver include: automatic self-survey to ensure accurate reference position for improved timing accuracy; the overdetermined timing mode provides an accurate 1 pps synchronised to GPS/UTC better than 15 nanoseconds (one sigma); timing receiver autonomous integrity monitoring to ensure high PPS integrity in overdetermined timing mode.

The modular design allows reduced integration time and low implementation risk. The receiver can increase network security.

The receiver uses a general purpose digital signal processor in lieu of a custom GPS chip to provide a true software GPS receiver. This allows flexible software since the receiver is no longer restricted by hardware design.

The timing receiver is an all-in-view, 12-channel, parallel tracking GPS device designed to operator with the L1 frequency, standard position service, coarse acquisition mode.
