Trimble Acutime 360 - Multi-GNSS (GPS, GLONASS, Beidou, Galileo) Smart Antenna

32 Channel Operation, Sealed Unit for Harsh Environments, Full -40 to +85C Operation

Introduction

The Trimble® Acutime™ 360 Multi-GNSS (GPS, GLONASS, Beidou, Galileo ready) smart antenna is the latest generation Acutime product of integrated GNSS technology in a rugged and weatherproof self-contained unit. The Acutime 360 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 360 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 360 Multi-GNSS smart antenna requires less than 1 Watt to operate. Once power is applied, the Acutime 360 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 360 smart antenna's T-RAIM (Time-Receiver Autonomous Integrity Monitor) algorithm ensures PPS integrity.

Designed for long-term reliability, the Acutime 360 smart antenna is corrosion-resistant and weatherproof, and has a rounded top that facilitates run-off from the elements.

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 360 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 360 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.

Acutime GG Starter Kit

Note that the Acutime 360 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).

Diamond Point Acutime cables:
Note: These are cables manufactured by Diamond Point in the UK. This is of similar specification to the Trimble Acutime cables although there are a few differences:
•Wires 11 and 12 have a different colour insulation. We include the colour guide on the product label (which is attached to the cable). Also available via PDF on request.
• A push on boot is used (IP67 rated) - the Trimble cables use a potted connector.
• Cable is significantly cheaper.
• Customised lengths available on request.
