Crossbow Announces New GPS-Aided Attitude and Heading Reference System --GPS-AHRS-- For The NAV420.Business Editors/High-Tech Writers SAN JOSE, Calif.--(BUSINESS WIRE)--June 9, 2004 Crossbow Technology, Inc., leading manufacturer of MEMS-based sensor systems, today announced a new series of solid-state Navigation Systems and Attitude and Heading Reference System (AHRS AHRS Attitude Heading Reference System AHRS Attitude and Heading Reference System AHRS Attempted Hours (educational transcript) AHRS Altitude Heading Reference System AHRS Army Human Resources System AHRS Automatic Heading Reference System ). The first product in the series, the GPS-aided NAV See navigation system and navigation bar. 420 sets new standards for value in MEMS-based sensing solutions. Highest Level of Integration Available The NAV420 packs an internal GPS with WAAS (Wide Area Augmentation System) A system of earth stations and satellites that improves the tracking accuracy of the GPS navigation system to approximately 10 feet. capability, a 3-axis MEMS-based accelerometer accelerometer Instrument that measures acceleration. Because it is difficult to measure acceleration directly, the device measures the force exerted by restraints placed on a reference mass to hold its position fixed in an accelerating body. cluster, a 3-axis MEMS-based rate sensor cluster, and a 3-axis magnetometer within a 3 inch cube. Outputs include a full navigation and position solution and a full attitude solution for roll, pitch, and heading. Built on Crossbow's Deployment History Crossbow has more experience than anyone in the industry placing MEMS (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s. sensors in difficult, real-world environments. The NAV420 incorporates all the knowledge gained in hundreds of industrial applications with challenging EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. , vibration, and temperature environments. The NAV420 is completely sealed against moisture and water, encased en·case tr.v. en·cased, en·cas·ing, en·cas·es To enclose in or as if in a case. en·case  ment n. in an EMI-resistant housing, and built for tough vibration and shock environments. Crossbow's patented inertial algorithms have been proven in land, sea, and aviation applications. Sets the Standards for Value and Performance with MEMS The Crossbow NAV420 offers the best of performance and price value. It is backed by our customer service and reputation for quality products that perform in difficult applications. It is a new industry standard for price and performance. Dean Johnson, Vice President for Inertial Systems, says, "Crossbow is the leader in providing high performance solutions at an affordable price. Our wide experience base and innovative design drive the features and performance of the new NAV420."
