Trimble’s new Acutime™ 2000 GPS smart antenna marks the integration of the latest GPS technology into a rugged selfcontained unit that enables easy integration into any system. The Acutime 2000 is a polemounted GPS receiver and antenna in a single environmentally sealed enclosure. The Acutime 2000 GPS smart antenna design continues Trimble’s line of GPS smart antennas, which have been in production since 1991. The antenna is the perfect solution for precise timing and synchronization of wireless voice and data networks and provides a cost-effective and independent timing source for any application, such as fault detection systems and synchronization of wireless networks. Once power is applied, the Acutime 2000 automatically tracks satellites and surveys its position to within meters. It then switches to overdetermined time mode and generates a pulse-per-second (PPS) output synchronized to UTC within 50 nanoseconds (one sigma), outputting a time tag for each pulse. The Acutime 2000 GPS smart antenna’s T-RAIM (TimeReceiver Autonomous Integrity Monitor) algorithm ensures PPS integrity.
