Description
商品說明 :
UM7 是第三代姿態和航向參考系統 (AHRS)，它利用最先進的 MEMS 技術來提高性能並降低成本。與其前身一樣，UM7 使用複雜的擴展卡爾曼濾波器結合三軸加速度計、速率陀螺儀和磁力計數據來產生姿態和航向估計。 UM7-LT 與 UM7 等效，不同之處在於它不包括外殼並且無法進行工廠校準。
UM7 還增加了許多新功能，包括更高的陀螺偏置穩定性和更低的噪聲、提高靈活性的新通信架構、可選的 NMEA 數據包傳輸、與外部 GPS 的 UTC 時間同步以及對所有傳感器的三階溫度補償的支持。 即使具有附加功能，與同級別的其他傳感器相比，UM7 的價格也大大降低。 UM7 帶有一個用於主 IO 接頭的 5 針電纜組件。還提供用於可選 IO 擴展接頭的額外 5 針電纜組件和 6 針組件。
~ 簡單說，用在機器人或移動車體上，就是可以知道行進的姿態和車頭方向啦 ~
A USB Expansion Board is available to make it easy to connect the UM7 to your computer. You can then use the Serial Interface software to configure the sensor, and view and log data in real-time.
High performance
- Excellent gyro bias stability over temperature
- Adjustable low-pass filter and EKF settings provide customisable performance for various applications.
- States and sensor data synchronised to GPS position and velocity using optional external GPS module.
- Supports alignment calibration and third-order bias and scale factor temperature compensation for accels, gyros, and magnetometer (optionally performed in-factory or by the end-user).
- Magnetometer soft and hard-iron calibration
Lower Cost
- State-of-the-art MEMS devices designed for mass-market consumer applications drastically lowers cost
- OEM version reduces overall cost, size, and weight
Ease of use
- Transmits data using human-readable NMEA strings, binary packets for higher efficiency, or a combination of both
- Flexible communication architecture allows UM7 to transmit any combination of data at individually adjustable rates
- Connects to the Serial Interface software to allow for real-time plotting of sensor data, logging, device configuration, and magnetometer calibration
