Alloy features

The Alloy GNSS reference receiver has the following features:

  • Robust, lightweight design – 1.75 kg (3.85 lb) (GNSS receiver and batteries).

  • Can be used as a rover, base station, or as both a rover and a base station.

  • Trimble xFill™ RTK service is already installed.

  • Trimble RTX worldwide corrections. See MSS Configuration.

  • Advanced Trimble dual Maxwell™ 7 GNSS chipset provide 672 channels for simultaneous satellite tracking of GPS, QZSS, GLONASS, Galileo, BeiDou, and NavIC satellites.

  • Trimble EVEREST Plus™ multipath signal rejection. See Receiver Options.

  • Trimble 360 receiver technology.

  • High-precision multiple correlator for GNSS pseudorange measurements.

  • Spectrum Analyzer to troubleshoot GNSS jamming.

  • Enhanced security option.

    The California Consumer Privacy Act (CCPA) is a data privacy law, effective from 1 January 2020. The law is intended to enhance privacy rights and consumer protection for residents of California, United States. It requires manufacturers of devices that connect “directly or indirectly” to the Internet to equip the devices with “reasonable” security features. The law requires that depending on the nature and purpose of the device, if a device can be accessed outside a local area network then the password for the device needs to either be unique for each device OR force the user of the device to set their own password. Although the law is currently specific to California, Trimble has chosen to implement the changes to all affected devices shipped from Trimble before 1 January 2020.

    Bluetooth security has been modified for enhanced security. For more information, see Bluetooth Configuration.

  • Unfiltered, unsmoothed pseudorange measurements data for low noise, low multipath error, low-time domain correlation and high-dynamic response.

  • Very low noise GNSS carrier phase measurements with <1 mm precision in a 1 Hz bandwith.

  • Signal-to-noise ratio reported in dB-Hz.

  • Proven Trimble low elevation tracking technology.

  • Proprietary Receiver Autonomous Integrity Monitor (RAIM) system to detect and reject degraded signals to improve position quality. See NMEA-0183 message: GBS.

  • Up to two internal, hot swappable, smart Lithium-ion batteries. See Batteries.

  • Bluetooth® wireless technology and Wi-Fi for cable-free, no-hassle, base or rover operation.

  • Advanced four-line reversible front panel display with Power button, Enter, Escape, and navigation arrow keys for control and monitoring.

  • 20 Hz standard output rate, upgradable to 50 or 100 Hz.

  • Seamless connection to the Trimble Pivot™ software.

  • Can operate as an autonomous base with corrections supplied via NTRIP, direct socket connections, or via external radio.

  • Full data logging functionality with HTTP or FTP download capabilities. See Network Configuration menu.

  • FTP push functionality supported.

  • File format conversion support for HTTP downloads.

  • Can act as an Network Time Protocol server.

  • Built-in Dynamic DNS client support.

  • HTTP or HTTPS web interface access is supported. See HTTP Server Config

  • Built-in multi-language support for the web interface. See Web interface menus

  • Operates within a VRS network or IBSS for conventional base station-free rover capability.

  • GPS (including GPS Block IIIA) and GLONASS supported as standard, upgradeable to receive Galileo, BeiDou, QZSS, and/or NavIC.

    NOTE – The Alloy receiver now supports the new GPS Block IIIA L1C signal. Please note that GPS III satellites are still launching and are not fully operational. The L1C signal frequency is 1575.42 MHz. The Alloy receiver requires a new option code to track the L1C signal. To obtain an upgrade code for the L1C signal, please contact Trimble Support (RTNS_Support@trimble.com) with the serial numbers of the receivers.

    NOTE – The Alloy receiver can track the new signals that are part of the third-generation of Beidou satellites:

    • B1C - 1575.42 MHz.

    • B2A - 1176.45 MHz.

    • B2B - 1207 MHz. Not currently supported in the Pivot software.

    The receiver includes an updated pseudorange to extend the tracking from 37 to 63 BeiDou satellites with an extended almanac. The Beidou tracking option is required for this improvement. If you already have the Beidou upgrade for the Alloy receiver, please contact support (RTNS_Support@trimble.com) to get a new key to track the B1C; B2A is already supported.

  • Five SBAS channels.

  • 8 GB memory standard, upgradeable to 24 GB.

  • RoHS compliant.

  • Anti-spoofing feature.
