The Trimble Maxwell™ 8 GNSS modules are the next generation line of high-precision positioning GNSS receivers designed to significantly extend mission uptime, while increasing integration and in-field operation efficiencies for OEMs and system integrators, as well as their end-users. They include the Trimble BD1090, BD1092, BD1092i and the BX1092i products.

The Trimble Maxwell 8 GNSS modules are powered by advanced technologies known collectively as Trimble Maxwell™ 8, which encompasses Trimble JammerGuard™ for anti-jamming mitigation, Trimble RTX®-NMA for anti-spoofing mitigation, and Trimble IonoGuard™ for solar scintillation protection. The receiver line also includes a host of hardware upgrades such as quad core processing for improved performance and MEMS-based timer oscillator for 10x improved vibration sensitivity.

The Trimble Maxwell 8 GNSS modules have a number of technology- and hardware-based improvements compared to their predecessors: quad-core processing; an upgraded MEMs oscillators and IMU for superior inertial positioning; new best-in-class anti-jamming technologies with improved anti-spoofing technologies; Xona Pulsar compatibility for low earth orbit signal integration; an open-sourced Linux operating system for faster approvals, development and retesting; the new Trimble Interference Toolkit to easily remove integration interference during development.

No. The Trimble BD9250 and BD9XX series of products are built around previous generation technology called Maxwell 7.

The new Trimble Maxwell 8 Technology is built around a set of both software and hardware innovations—including the 8th generation baseband GNSS ASIC (application-specific integrated circuit) architecture, with onboard quad-core processing. This extra processing capacity improves CPU task performance and sensor fusion capabilities, additionally supported by the upgraded IMU and MEMs oscillator hardware components.

In this way, Trimble Maxwell 8 Technology innovations are made possible by the hardware upgrades of the Trimble Maxwell 8 GNSS modules, and exist solely on the 1090 series of modules, at this time.

Trimble JammerGuard, RTX-NMA and IonoGuard are three technological innovations that are collectively included as part of Trimble Maxwell 8 Technology. Each innovation combats different forms of radio frequency interference—GNSS jamming, GNSS spoofing, and solar or ionospheric scintillation, respectively. These intentional and unintentional forms of interference can significantly disrupt or disable high-precision positioning performance.

Trimble JammerGuard provides continuous high accuracy and reliable positioning by actively monitoring and minimizing unwanted interference across all GNSS frequency bands. This is accomplished through a multi-layered approach that spans hardware radio frequency features and digital signal processing, to positioning software. The core JammerGuard features include: antenna and RF front-end filtering, high resolution digitization, advanced DSP jam mitigation, resilient tracking loops, an agnostic PVT engine and situational awareness toolkits.

Trimble RTX-NMA seeks to detect both fake GNSS signals and faulty ephemeris data preventing the receiver from calculating erroneous positions that could significantly deviate from the actual position. Together with Galileo OSNMA, comprehensive security is provided across multiple constellations.

Trimble IonoGuard tracks multiple signals independently, and responds to solar/atmospheric events which create ionospheric scintillation by seamlessly switching to unaffected signals, preventing loss of lock on GNSS phase tracking.

All three technologies work in tandem automatically during in-field missions as anti-jamming, anti-spoofing and solar scintillation protection to ensure that users receive reliable, uninterrupted GNSS receiver performance.

Trimble JammerGuard technology is effective at drastically reducing the negative effects of intentional jamming threats, including: pulse jamming, chirp jamming, continuous wave (CW) jamming, swept continuous wave (SCW) jamming, and more. JammerGuard provides a powerful defense mechanism for GNSS positioning signals. By enabling receivers to handle jamming broadly, it far exceeds typical anti-jamming technologies in the market that mitigate a select few jammer types rather than the full spectrum.

Combining this anti-jamming technology with the power of Trimble RTX-NMA and Trimble IonoGuard for additional anti-spoofing and ionospheric scintillation protection provides a proven, comprehensive approach to combating radiofrequency interference for GNSS or GPS receivers at all levels.

The Trimble Interference Toolkit is an on-board program accessed via the receiver's web interface, designed to help users detect and interpret how radio frequency interference affects their positioning, and how the system automatically mitigates this interference. The Toolkit’s streamlined, easy-to-navigate interface indicates: which frequencies are impacted, how severely they are affected, and depicts what the signal looks like before and after the mitigation processing is applied. Visual plots demonstrate how the mean C/No of tracked signals is impacted—and the effect this has on the position solution’s error estimates—with the purpose of guiding users to evaluate their position reliability.

Yes, all Trimble Maxwell 8 GNSS modules support centimeter-level RTK accuracy.

Trimble Maxwell 8 GNSS modules are designed for high-precision, robust positioning performance across a wide range of industries, including: mining, construction, marine construction and surveying, robotics and autonomous systems. They are particularly well-suited for applications requiring high-performance accuracy, availability and integrity, while operating in environments susceptible to regional or near-field disruptions and malicious interference. Additionally, their tight-coupling with improved onboard inertial sensors provides optimal, ruggedized performance in heavy industry applications prone to high vibration and GNSS-denied signal reception.
