Trimble Acutime GG - Multi-GNSS (GPS, GLONASS, QZSS) Smart Antenna
12 Channel Operation, Sealed Unit for Harsh Environments, Full -40 to +85C Operation
Introduction
The Trimble® Acutime™ GG Multi-GNSS (GPS, GLONASS, QZSS) smart antenna is the latest generation Acutime product of integrated GNSS technology in a rugged and weatherproof self-contained unit. The Acutime GG is an integrated pipe thread-mounted multi-GNSS receiver, antenna and power supply solution in a single environmentally sealed easy to install enclosure.
The Acutime GG multi-constellation smart antenna design continues Trimble's line of GPS smart antennas, which have been in production since 1991.
This antenna is the perfect solution for precise timing and network synchronization needs, including broadband wireless applications. It provides an extremely cost-effective and independent (within the firewall) timing source for any application, such as fault detection systems and synchronization of wireless networks.
Power Efficiency
The Acutime GG Multi-GNSS smart antenna requires less than 1 Watt to operate. Once power is applied, the Acutime GG smart antenna automatically tracks satellites and surveys its position to within meters. It then switches to overdetermined time mode and generates a pulseper- second (PPS) output synchronized to UTC within 15 nanoseconds (one sigma), outputting a time tag for each pulse. The Acutime GG smart antenna's T-RAIM (Time-Receiver Autonomous Integrity Monitor) algorithm ensures PPS integrity.
Designed for long-term reliability, the Acutime GG smart antenna is corrosion-resistant and weatherproof, and has a rounded top that facilitates run-off from the elements.
Acutime Gold/Acutime 2000 Compatability
There are two versions of the Acutime GG available with the only difference being the firmware defaults. The first version defaults to GPS only operation and should be a plug in replacement for previous Trimble Smart antenna users such as the Trimble Acutime Gold and Trimble Acutime 2000 (note that the Acutime 2000 was available with RS-232 and RS-422 options whereas the Acutime GG is RS-422 only). The second version defaults to full GNSS operation. Both models share identical hardware - only the firmware defaults differ.
Physical Interface
The RS-422 interface is ideal for long cable runs required by buildings or towers. Standard cables are available in lengths up to 400 feet. Custom lengths up to 1800 feet may be ordered.
Getting Started
The Acutime GG Starter Kit makes it easy to evaluate the exceptional performance of this multi-GNSS smart antenna and integrate state-of-theart technology into your system. The Starter Kit includes the Acutime GG smart antenna (RS-422), a 100' interface cable, user guide, RS-422 to USB converter, and a Microsoft® Windows® software tool for monitoring and communication.
Note that the Acutime GG is not USB based - its RS-422. The starter kit contains a USB to RS-422 converter, so you can connect it to your PC (via the USB port) conveniently. The unit will appear as two additional COM ports to application software (i.e. on a PC with only COM1 onboard, the unit will appear as COM2 and COM3).
