Motus is an ultra-high accuracy MEMS IMU that combines low SWaP-C (Size, Weight, Power, and Cost) and FOG-like performance.

Motus is a miniature ultra high accuracy MEMS IMU. It features some of the highest accuracy MEMS accelerometers and gyroscopes currently available combined with magnetometers. Motus is fully calibrated for all sensor errors over a wide temperature range and can be software upgraded to AHRS or INS functionality. It is available in both OEM and enclosed packages.  ITAR Free!

FEATURES特点

ULTRA HIGH ACCURACY MEMS SENSORS 超高准确度MEMS传感器

Motus features some of the highest accuracy MEMS accelerometers and gyroscopes currently available. Motus's inertial performance exceeds some FOG IMUs and is up to 100x smaller and 10x cheaper. Motus is put through Advanced Navigation's intensive calibration process to provide consistently accurate data over an extended temperature range of -40°C to 85°C. As part of this calibration, every Motus unit spends 22 hours in our specially built rotating temperature chamber.

MINIATURE PACKAGE 细小封装

Never before has such high inertial performance been available in such a small package. Motus consumes just over 1 cubic inch in volume and weighs only 26 grams. This makes it ideal for weight and size sensitive applications. Motus is available in an OEM package suitable for integration into larger products or an enclosed package for external and standalone use.

AHRS OR INS UPGRADEABLE 航姿参考系统或惯导系统可升级

Motus can be upgraded to full AHRS or INS capability through a software license upgrade. As an INS it can be interfaced to any of the leading brands of GNSS receivers to create an OEM GNSS/INS solution.

ADVANCED SIGNAL PROCESSING 先进信号处理

Motus samples its sensors synchronously at 1000Hz through six individual 24-bit differential ADCs which minimises noise as well as providing optimal thermal calibration and performance characteristics. The sensor data is fully compensated for coning and sculling at any data rate output that is chosen. 14 seperate heavily filtered regulated power supplies ensure that each sensor and ADC is operating off the cleanest possible power supply.

APPLICATIONS应用

UAV GEOPOINTING 航测

UAV geopointing applications require repeatably low sensor biases and scaling errors to minimise attitude error and acheive the highest accuracy ground target position. Motus is ideal for this application with its extremely high sensor performance. Its incredibly small size and weight allows for easier integration and longer flight times on VTOL vehicles.

无人机航测应用要求重复的低传感器偏差和缩放误差,以最小化姿态误差并实现地面目标位置最高精度。Motus是该应用的理想选择,具有极高的传感器性能。其非常小的尺寸和重量使得在VTOL垂直起飞飞行器上更容易集成和更长的飞行时间。

UAV LIDAR无人机激光探测与测量

Motus is ideal for the booming VTOL LIDAR market which requires very high accuracy inertial data in a very light package. Motus can add the power of FOG to your VTOL aircraft without weighing down the operating time.

正在兴起的垂直起飞飞行器激光雷达市场,要求非常高准确度惯性数据和非常轻的封装。Motus能提供光纤导航的性能,又不至于因重量拖累飞行时间。

MARINE SURVEYING 海洋调查

Marine surveying applications require accuracy and repeatability that historically only FOG systems have been able to offer.  Motus can now be used in place of these systems and with its incredibly small size it can be integrated directly into sensor heads, eliminating errors due to alignment offsets and mechanical play. By installing the AHRS or INS upgrade license Motus can generate high accuracy roll, pitch, heading and heave on board.

海洋调查应用要求的精度和重复性传统上只有光纤导航系统能提供。Motus现在能代替光纤导航系统,其难以想象的小尺寸可以直接集成到传感器中,消除由于重置偏差和机械摆放带来的误差。安装AHRS或INS升级许可,Motus能输出高精度摇摆、倾斜、偏航和升沉数据。

POST PROCESSING后处理

In combination with post processing software, Motus can be used to generate very high accuracy post processed inertial position, velocity and orientation data. The high accuracy Motus inertial data can be fused with any GNSS receiver capable of recording raw RINEX data.

加上后处理软件,Motus能用来输出非常高准确度的后处理惯性定位、速度和方向数据。这些惯性数据能与任何具有输出RINEX格式原始数能力的GNSS接收机的数据融合。
