Trimble has rolled out its latest generation of timing receivers in the form of the Acutime GG smart antenna with multi-Global Navi-gation Satellite System (GNSS) capabilities.
Slightly larger than a baseball and housed in a rugged, environmentally sealed enclosure, the antenna provides a pulse-per-second (PPS) output synchronised to UTC within 15 nanoseconds (one sigma). In addition to GPS and GLONASS, it also supports Satellite Based Augmentation Systems (SBAS) and the Asian Pacific Quasi-Zenith Satellite System (QZSS).
The new Acutime GG smart antenna is backwards compatible with applications built around previous generations of Acutime receivers, and is a suitable solution for precise timing and network synchronisation. It provides an independent GNSS timing source, within the firewall, for a variety of applications including:
* Synchronisation and timing of cellular and radio networks.
* Network fault detection systems.
* Time Difference of Arrival (TDOA) applications.
* Supervisory Control and Data Acquisition (SCADA) systems.
Once powered, the antenna automatically tracks satellites and surveys its position to within metres. It then switches to over-determined time mode and generates a PPS, outputting a time tag for each pulse. The antenna’s Time-Receiver Autonomous Integrity Monitor (T-RAIM) algorithm ensures PPS integrity.
Designed for long-term reliability, the Acutime GG is a pole-mounted GNSS 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 is ideal for the long cable runs required by buildings or towers. Standard cables are available in lengths up to 122 m. Custom lengths up to 550 m are available.
The Acutime GG can operate in extreme temperatures (-40°C to +85°C) and hostile RF-jamming environments typically encountered at wireless network transmitter sites. It requires less than 1 W to operate and outputs Trimble’s Standard Interface Protocol (TSIP) or industry-standard NMEA.
The Acutime GG Starter Kit makes it easy to evaluate the performance of the antenna. It includes the antenna (RS-422), a 30 m interface cable, user guide, RS-422 to USB converter, and a Windows software tool for monitoring and communication.
