Embedded Navigation Solutions
VectorNav VN-300 Dual Antenna GPS/INS
High-Performance Embedded Navigation
PRODUCT OVERVIEW
VectorNav Technologies introduces the VN-300, the
world’s smallest and lightest high-performance
Dual Antenna GPS-Aided Inertial Navigation System
(GPS/INS). Building on the architecture of the
currently available VN-100 line of IMU/AHRS as well
as the VN-200 line of GPS/INS, the VN-300 enables a
wider range of applications through the
incorporation of GPS-compass techniques. The
VN-300 is ideal for applications that require a highly
accurate inertial navigation solution under both
static and dynamic operating conditions, especially
in environments with unreliable magnetic heading
and good GNSS visibility.
Incorporating the latest solid-state MEMS sensor
technology, the VN-300 combines 3-axis
accelerometers,
gyros,
magnetometers,
a
barometric pressure sensor, two GNSS receivers,
and a low-power micro-processor into a rugged
aluminum enclosure or surface mount package.
The VN-300 couples measurements from the
onboard GNSS receivers with measurements from
the onboard inertial sensors to provide position,
velocity, and attitude estimates of higher accuracies
and with better dynamic performance than a
standalone GPS or GNSS receiver or AHRS.

HIGHLIGHTS
Coupled position, velocity, & attitude estimates
Static accuracy better than 0.3° heading, 0.5° pitch & roll
Dynamic accuracy better than 0.3° heading, 0.1° pitch & roll
Dual 72 Channel GNSS receivers
Built-in Extended Kalman Filter running at 400 Hz
Automatic and seamless transition between magnetic
heading (AHRS) mode (used on start-up and in GPS-denied
environments), INS operation in dynamic conditions, and
GPS-compass in static conditions
True INS filter - no mounting orientation requirements
Real-time gyro & accelerometer bias compensation
Raw pseudorange, Doppler, & carrier phase outputs
Individually calibrated for bias, scale factor, misalignment,
