SUNNYVALE, CalifTrimble introduced the Acutime Gold Global Positioning System (GPS) timing receivers. Slightly larger than a baseball and housed in a rugged, environmentally sealed enclosure, the Acutime Gold provides a pulse-per-second (PPS) output synchronized to UTC within 15 nanoseconds (one sigma). It is designed to be a small, accurate and cost-effective solution for adding GPS timing and synchronization into any application where ease of installation and long-term reliability is critical.
The Acutime Gold GPS smart antenna is directly compatible with applications build around previous generation Acutime 2000 receivers. The antenna is well suited for precise timing and network synchronization, including broadband wireless applications. It provides an independent timing source, within the firewall, for any application such as network fault detection systems and synchronization of wireless networks. Applications include synchronization and timing of paging, cellular and radio networks, network fault detection systems, time Difference of Arrival (TDOA) applications, and supervisory control and data acquisition (SCADA) systems.
Once power is applied, the Acutime Gold automatically tracks satellites and surveys its position to within meters. It then switches to over determined time mode and generates a PPS (outputting a time tag for each pulse). The Acutime Gold GPS smart antenna's T-RAIM (Time-Receiver Autonomous Integrity Monitor) algorithm ensures PPS integrity.
Designed for long-term reliability, the Acutime Gold GPS smart timing antenna is a pole-mounted GPS receiver and antenna. It is corrosion-resistant and waterproof, and has a rounded top that facilitates run-off from the elements. The RS-422 interface enables long cable runs required by buildings or towers. Standard cables are available in lengths up to 400 feet. Custom lengths up to 1800 feet are available.
The Acutime Gold can operate in extreme temperatures (-40 to +85 degrees Celsius) and hostile RF-jamming environments typically encountered at wireless network transmitter sites. It requires less than 70mA at 12 volts and outputs Trimble's standard interface protocol (TSIP) or industry-standard NMEA.
A Starter Kit is available to evaluate performance. It includes the Acutime Gold GPS smart antenna (RS-422), a 100 foot interface cable, user guide, RS-422 to USB converter, and a Windows software tool for monitoring and communication. In addition, the Acutime Gold GPS smart timing antenna has been designed to meet restrictions on the use of hazardous substances under the RoHS European Directive.
The Acutime Gold GPS smart timing antenna is expected to be available in production quantities in the second quarter of 2006. Click here for the data sheet.
