PNI Prime

3-axis measurement Hard- and soft- iron correction Integrated Processor Low power consumption

Description

Overview

A full-featured 3-axis digital compass designed for flexibility and adaptability — the perfect fit for sonobuoys, ADCPs, sidescan sonar, low-cost robotics, and other cost-sensitive applications.

The highest-performance 3-axis compass module in its price range, PNI's Prime provides pitch, roll and compass heading everywhere, including where GPS is compromised or unavailable — underwater or underground, beneath bridges or inside buildings. The low-power consumption, low-cost Prime provides all-digital compass heading outputs accurate to 1 degree, can be calibrated to account for magnetic distortions, and offers several user programmable parameters including output damping, reporting units, and sampling configuration.

Full featured digital compass

Combining PNI's low-power consumption magneto-inductive sensors with a 3-axis MEMS accelerometer, Prime is a low-cost compass that provides accurate heading and tilt readings, even at high and low latitudes. PNI's advanced hard and soft iron correction algorithms allow for compensation of magnetic distortions inherent in the user's system, resulting in reliable and consistent readings.

By leveraging PNI's patented magneto-inductive sensors with intelligent power-saving algorithms, Prime consumes less than half the power of magneto-resistive-based compasses. Unlike competetive products, Prime works well at high and low latitudes where the earth's magnetic field has a very high Z-axis component. Prime is the compass of choice for low-cost robots, sonobouys, acoustic Doppler current profilers (ADCPs), sidescan sonar, and seismic monitoring equipment.
