Detailed description

The Navico Precision 9 compass is a solid-state heading sensor that provides accurate navigation data for Simrad, Lowrance, and B&G autopilots, radars, and instruments. It transmits heading, rate of turn, roll, pitch, and heave data via the NMEA 2000 network. Its technology integrates a 9-axis solid-state sensor array for reliable measurement of vessel motion under all conditions.

Performance and Technical Data

The Precision 9 compass ensures heading accuracy of ± 2° after calibration, with a repeatability of ± 1.0° or better. It operates over a roll and pitch range of ± 45°. The sensor connects directly to the NMEA 2000 network (8-16V power) with very low power consumption of 0.4W, representing an LEN load of 1. It is IPX7 waterproof certified. The module weighs 165 g, and its mounting bracket weighs 130 g. It transmits standard NMEA 2000 PGNs: 127250 (Heading), 127251 (Rate of Turn), 127257 (Attitude), and 127252 (Heave), ensuring broad compatibility.

Installation and Advanced Calibration

The Precision 9 can be installed on a flat surface, horizontally or vertically (bulkhead), using its included mounting bracket. For optimal performance, it should be placed away from magnetic interference. The compass features two calibration modes: manual calibration controlled from a compatible multifunction display, and an intelligent automatic calibration mode. The latter continuously adjusts parameters to maintain the best possible accuracy based on changes in the Earth's magnetic field, with several operating modes (Auto, Locked, Enabled, Disabled) to suit user needs.

Market Positioning: Precision 9

The Navico Precision 9 compass is the reference sensor for the Navico ecosystem, essential for the proper functioning of Simrad (NAC-2, NAC-3) and B&G autopilots, as well as for stabilizing radar overlays and MARPA functions. Compared to competitors like the Garmin SteadyCast, the Precision 9 offers better heading accuracy (±2° vs. ±3°) and additionally provides heave data, crucial for stabilizing certain sounders. Against the Raymarine EV-1 sensor, which is at the heart of the SeaTalkNG ecosystem, the Precision 9 positions itself as a universal and easy-to-integrate NMEA 2000 component. It represents a high-performing middle ground, offering a clear advantage over older fluxgate compasses (like the RC42) without reaching the cost of very high-precision sensors like the Airmar H2183, making it the ideal choice for the majority of recreational vessels and small professional units.

« Installation Review: A 9-axis heading sensor offering ± 2° accuracy for 0.4 W over NMEA 2000 »

The Precision-9 compass is much more than a simple heading sensor; it is a true compact attitude center, essential for the performance of modern autopilot and stabilization systems. Based on 9-axis semiconductor sensor technology (MEMS), it provides heading, Rate of Turn, roll, pitch, and heave data with great reliability. Its heading accuracy of ±2° after calibration and repeatability of ±1.0° are performance guarantees for true wind calculations and radar target overlay (MARPA).

In the field, its robustness is ensured by an IPX7 waterproof housing. However, its operational reliability depends entirely on the quality of its installation. It is imperative to position it as close as possible to the dynamic center of gravity of the vessel and at a minimum distance of 2 meters from any source of magnetic interference, such as engines or pilot actuators. Its automatic calibration algorithm is a major strategic asset: it continuously refines its parameters during navigation, adapting to changes in the Earth's magnetic field or the addition of equipment on board, thus ensuring constant accuracy without tedious manual intervention.

In terms of system integration, the Precision-9 is a model of efficiency. Connected via the NMEA 2000 network, it represents a very low network load with a LEN (Load Equivalence Number) of 1. It broadcasts standard PGNs (127250, 127251, 127257, 127252), ensuring native compatibility and smooth data transmission to MFDs, autopilots, and radars. This compass is the cornerstone of an integrated navigation system, providing the raw data essential for the intelligence of advanced autopilot algorithms.
