GPS aided Orientation Sensor
GPS輔助型組合導航系統(tǒng)
The IG-500N is the world smallest 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是世界上最小的帶有GPS輔助定位的姿態(tài)航向參考系統(tǒng)系統(tǒng)（AHRS）。IG-500N擁有嵌入式的擴展卡爾曼濾波器，使其在高速動態(tài)條件下能夠提供無與倫比的姿態(tài)和方位測量精度。
All in one: the IG-500N
集成所有功能于一體: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由基于微機電系統(tǒng)(MEMS)的慣性測量單元(IMU)、GPS接收器和壓力傳感器組成。它能夠在長時間內(nèi)提供精確的無漂移的姿態(tài)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.
本微型慣性導航系統(tǒng)(INS)運行了一個實時的擴展卡爾曼濾波器，能以最高達100 Hz的刷新頻率來計算方向、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.
相比傳統(tǒng)的姿態(tài)航向參考系統(tǒng)，IG-500N通過去除GPS接收機所測量的瞬時加速度的方法得到精度上的提高。
