Многофункциональный датчик ориентации UM7-LT UM7-LT Orientation Sensor

Датчик ориентации третьего поколения UM7-LT объединяет в себе трехосный гироскоп, акселерометр и магнитный датчик. Датчик подключается посредством TTL UART или SPI интерфейса. Также, добавлено много новых возможностей, в том числе более высокая стабильность гироскопа смещения и низкий уровень шума, новая архитектура связи для повышения гибкости, передача NMEA пакетов, UTC синхронизация с внешним GPS, поддержка третьего порядка температурной компенсации для всех датчиков.

Даже с дополнительными функциями, UM7 предлагается по значительно сниженной цене, по сравнению с другими датчиками в своем классе. UM7 поставляется с одним 5-контактным кабелем для основного ввода-вывода. Используя USB адаптер, UM7 может быть подключен непосредственно к компьютеру.

The UM7 is a 3rd-generation Attitude and Heading Reference System (AHRS) that takes advantage of state-of-the-art MEMS technology to improve performance and reduce costs. Like its predecessors, the UM7 combines triaxial accelerometer, rate gyro, and magnetometer data using a sophisticated Extended Kalman Filter to produce attitude and heading estimates.

The UM7 also adds many new features, including higher gyro bias stability and lower noise, a new communication architecture for improved flexibility, optional NMEA packet transmission, UTC time-synchronization with external GPS, and support for third-order temperature compensation on all sensors.
Even with its added features, the UM7 is offered at a significantly reduced priced compared to other sensors in its class.

The UM7 comes with one 5-pin cable assembly for the main IO header. Extra 5-pin cable assemblies and 6-pin assemblies for the optional IO expansion headers are also available.
A USB Expansion Board is also available to allow the UM7 to be connected directly to your computer.

High performance
- Excellent gyro bias stability over temperature
- Adjustable low-pass filter and EKF settings provide customizable performance for various applications.
- States and sensor data synchronized 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 CHR Serial Interface software to allow for real-time plotting of sensor data, logging, device configuration, and magnetometer calibration
