ABX Series are state-of-the art GNSS sensors intended for general-purpose, real-time, high-accuracy, absolute positioning applications, with additionally accurate heading measurements and relative positioning for some of the available models.

Ruggedness

All receivers from the ABX series share the same weatherproof, lightweight, small-sized and rugged enclosure capable of accommodating either one GNSS MB100 board (ABX100), one GNSS MB800 board (ABX800) or two GNSS MB800 boards (ABX802).

Designed for seamless integration, ABX Series allows OEM and system integrators to rapidly integrate centimeter level positioning into their application. Each receiver from the ABX series is fi tted with a built-in power supply extending the input voltage range to between 9 and 36 V DC while maintaining a low power consumption regardless of the power input voltage.

Built in a weatherproof, rugged and small-size unit, the ABX receivers can be operated in harsh environments while requiring a minimum of space for their installation. As lightweight high-end units, all ABX receivers are also compatible with airborne applications for which weight considerations are critical.

Additionally, industry standard and independent I/O connectors simplify cabling for system integrators. Smart mounting bracket design allows seamless integration on board a machine or a vehicle for land, air or sea operations. Being a “plug and play” system, it is ideally suited for mobile positioning and navigation onboard-solutions for which precision and flexibility are equally important.

Latest state-of-the art XDL Micro UHF Transceiver (TRx) from Pacifi c Crest are also available with ABX800 and ABX802 models.

High-End Performance

ABX receivers are smart GNSS receivers built around the GPS/GLONASS/SBAS, single- or dualfrequency MB100 or MB800 board recently introduced in the market. Embedded Z-Blade™ technology in the board ensures powerful performance and a patented way to use multiple GNSS constellations for high-accuracy positioning solutions

• Fast initialization and accuracy at long-range,
• Patented multi-constellation signal processing,
• RTK solution maintained if data link is briefl y dropped,
• Dependable Heading + Pitch/Roll measurements with baseline auto-calibration,
• Advanced multi-path mitigation and robust signal tracking for maximum data reliability,
• Unique Z-Blade “GNSS-centric” technology for outstanding GNSS performance in harsh environments.

With the unique “Internal Heading” capability of the MB100 the ABX100 is an ideal low-cost solution for vector determination applications (Heading + Pitch/Roll) + SBAS/DGPS positioning, while the ABX802 is capable to deliver Heading + Pitch/Roll information in highly demanding environments in addition to outstanding RTK positioning.
