GPS aided Orientation Sensor
GPS輔助型組合導(dǎo)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是世界上比較小的帶有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(kuò)展卡爾曼濾波器，使其在高速動(dòng)態(tài)條件下能夠提供的姿態(tài)和方位測(cè)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(jī)電系統(tǒng)(MEMS)的慣性測(cè)量單元(IMU)、GPS接收器和壓力傳感器組成。它能夠在長(zhǎng)時(shí)間內(nèi)提供精確的無(wú)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(dǎo)航系統(tǒng)(INS)運(yùn)行了一個(gè)實(shí)時(shí)的擴(kuò)展卡爾曼濾波器，能以達(dá)100 Hz的刷新頻率來(lái)計(jì)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(guò)去除GPS接收機(jī)所測(cè)量的瞬時(shí)加速度的方法得到精度上的提高。
