The 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.  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 user-configurable for a wide variety of applications.

For customers wishing to use the NAV440 in analog data acquisition systems, MEMSIC offers the NAV-DAC440 analog interface adapter. The NAV-DAC440 converts the NAV440 serial digital data to 9-channel BNC analog outputs.
