Powerful Sensing Solutions for a Better Life
NAV440
GPS-AIDED MEMS INERTIAL SYSTEM
The MEMSIC NAV440 is a fully-integrated
GPS-aided attitude & heading reference system
and GPS navigation solution. The NAV440
provides full inertial data (angles, rates, accels) and
GPS position, along with inertially derived velocity
that provides significant improvement in stability
and latency compared with stand-alone GPS
velocity measurements.
Features
• Complete GPS-Aided AHRS Solution
• Accuracy < 0.2 deg
UAV Flight Control
• Output Data Rate > 100Hz
Land Vehicle Guidance
The NAV440 combines highly reliable MEMS sensors, magnetometers,
and a WAAS/EGNOS-enabled GPS receiver all in a small and rugged
environmentally sealed enclosure. The NAV440 provides consistent
performance in challenging operating environments, and is userconfigurable for a wide variety of applications.
