Watson Industries continues to change along with the seasons to manufacture superior inertial measurement products that will meet all of your application needs. Take this opportunity to contact our Engineering staff at +1-715-839-0628 to discuss your requirements. We can design a sensor to meet your specific application needs.

Tip of the Month

Watson Industries exports products all over the world. The majority of our products are listed under ECCN 7A994. The export process starts with the completion of Watson Industries End User Statement to determine if an export license is required. We strive to make the export process as easy as possible. More details about our export policy and our End User Statement can be found on our website on our export page. You can also call and talk to one our experienced customer service personnel at +1-715-839-0628.

Attitude & Heading
Reference System

An Attitude and Heading Reference System (AHRS) is an inertial sensor installation that provides critical attitude
reference and heading reference information for aircraft. This information can then be relayed to any of the aircraft’s systems that require it, such as flight controls, flight deck displays and weather radar antenna platforms, among others.

An AHRS can also be used in highly dynamic marine and ground environments. Typical applications include platform stabilization, undersea ROV piloting, land vehicle guidance, avionics, and robotic systems control. Solid-state AHRS offers superior reliability and accuracy to the more traditional mechanical gyroscopic instruments.

This AHRS-S305 differs from our other inertial gyro packages because it uses MEMS gyros that are smaller and less expensive than our line of VSG angular rate sensors. This makes the AHRS-S305 more economical and half the size of the AHRS-E304 attitude reference that uses VSG gyros for enhanced accuracy and signal stability.

AHRS-S305 Features:

  • Solid State, Strap Down System
  • Rugged, High Reliability
  • Vibration Resistant
  • Triaxial Angular Rate Output
  • Triaxial Acceleration Output
  • Triaxial Fluxgate Magnetometer
  • RS-232 Serial Data Outputs
  • Analog Data Outputs
  • PC Heading Calibration
  • No Moving Parts
  • No Lubrication or Service Requirements
  • One Year Limited Warranty
  • Engineering Support

Feel free to call with any application needs or questions. We look forward to working together to help design and manufacture a sensor that meets your specifications.


The AHRS-S305 is useful for land, sea, and aerospace applications. Some of the many applications for this sensor include:

  • Land
    • Unmanned Vehicles
    • Road Surface Measurement
    • Robotics Research
  • Ocean
    • Cable Laying
    • ROV Control Display
    • Unmanned Vehicles
  • Aerospace
    • Stabilized Camera
    • UAV Control Display
    • Drone, Primary Gyro
    • UAV: Research
    • Unmanned Vehicles
    • Backup Attitude Instrument
    • Heading Reference

Here are two applications for our AHRS-S305 sensors. Our website provides suggested sensors for more of our aerospace, land and ocean applications.

Remotely Operated Vehicles (ROVs)

Normally, small submersibles are stabilized by the pilot’s actions in response to the orientation of the sub. In the case of an ROV, the pilot is not on board so there is no human “feel” for the orientation of the vehicle. This situation can lead to damage or loss of the submersible. Since the cost of the vehicles as well as the expense of at-sea operations is quite high, a sensor package is necessary that can reliably transmit accurate data on the attitude of the sub.

Remotely operating a submersible requires a full attitude gyro sensor. Heading data is necessary to navigate the vehicle to its destination. Pitch and roll data is also required to provide an accurate picture of the vehicle’s orientation. Other important features of the gyro package are wide bandwidth, low power consumption, and high reliability.


Unmanned Aerial Vehicles: Control & Display

Piloting an aerial vehicle remotely is a challenging task. There is no pilot in the craft to monitor its position with respect to the ground. Controlling the cost of the vehicle is important, but the cost of a losing an UAV due to inadequate sensors is much higher.

A sensor package that can quickly and accurately deliver data on vehicle attitude and heading is crucial. A system built using solid-state gyros is favorable when considering cost and reliability.

Watson Industries has several sensor packages that can provide UAV attitude data to the remote pilot. We manufacture several types of Attitude and Heading Reference Systems (AHRS) and Dynamic Measurement Systems (DMS) that can meet your requirements.


Our AHRS-S305 sensors are ideal for these applications and many others. They have provided accurate data and reliable performance for customers in these fields for many years.
