GPS aided Orientation Sensor
GPS辅助型组合导航系统
The IG-500N is the world *allest GPS enhanced Attitude and Heading Reference System (AHRS). With its embedded Extended Kalman Filter, the IG-500N delivers unmatched precision for attitude and position measurements in very high dynamic conditions.
IG-500N是*小的带有GPS辅助定位的姿态航向参考系统系统（AHRS）。IG-500N拥有嵌入式的扩展卡尔曼滤波器，使其在*动态条件下能够提供*的姿态和方位测量精度。
All in one: the IG-500N
集成*功能于一体:IG-500N
The IG-500N includes a MEMS based Inertial Measurement Unit (IMU), a GPS receiver and a pressure sensor. It provides precise drift-free attitude and position, even in long time turns.
IG-500N由基于微机电系统(MEMS)的惯性测量单元(IMU)、GPS接收器和压力传感器组成。它能够在长时间内提供*的无漂移的姿态信息和位置信息。
This miniature Inertial Navigation System (INS) runs a real time, on board, Extended Kalman Filter that computes orientation, position and velocity data at high update rates, up to 100 Hz.
本微型惯性导航系统(INS)运行了一个实时的扩展卡尔曼滤波器，能以**100 Hz的刷新频率来计算方向、位置和速度信息。
The attitude accuracy is also improved, compared to traditional AHRS, by removing transient accelerations measured by the GPS receiver.
相比传统的姿态航向参考系统，IG-500N通过去除GPS接收机所测量的瞬时加速度的方法得到精度上的*。
