	Spatial sensors from Phidgets use AHRS (Attitude and Heading Reference System) ~~or IMU~~ algorithms to combine data from accelerometers, magnetometers and gyroscopes into a calculation of the device’s orientation more precise than could be achieved by any of the sensors individually.		Spatial sensors from Phidgets use AHRS (Attitude and Heading Reference System) algorithms to combine data from accelerometers, magnetometers and gyroscopes into a calculation of the device’s orientation more precise than could be achieved by any of the sensors individually.

	While this process is by no means straightforward, PhidgetSpatial sensors come with built-in AHRS calculations combining data from all three types of sensors out of the box. By using the Phidget Spatial object in your code, you can get a direct reading of the heading of your device, in both Euler angle and Quaternion form.

	The AHRS parameters are used to determine certain characteristics of your system so the AHRS algorithm can make better assumptions about the movement in your system. Each of these parameters will have recommended values as a starting point for your Phidget in a [[#Suggested Parameters\|table]] below.

			All AHRS settings will apply to a system using the IMU algorithm in exactly the same ways, except the compass readings and related settings will be ignored when using IMU.

	For completeness, we have included a selection to set AHRS to more or less ignore input from the magnetometers and ~~gyroscopes~~. By selecting this sample, you can see how the gyroscopes will drift over time and fast motions, clearly demonstrating the need for the accelerometer and magnetometer to bring the gyros back into alignment.
