PhidgetSpatial Precision 3/3/3 High Resolution

ID: 1044_0

This spatial board has a 3-axis accelerometer, gyroscope and compass with high resolution readings at low magnitudes.

Replaced by 1044_0B

Replaced by the 1044_0B - PhidgetSpatial 3/3/3 Precision. It is the same device, but it comes pre-assembled into a plastic shell enclosure and you can choose which length of USB cable to include.

The PhidgetSpatial Precision 3/3/3 combines the functionality of a 3-axis compass, a 3-axis gyroscope, and a 3-axis accelerometer all in one convenient package. It has enhanced precision in the accelerometer when measuring less than ±2g, and enhanced gyroscope precision at speeds less than 100°/s. The transition from high precision to low precision mode and back is completely seamless and automatic.

If precision is not an important factor for your application, consider the 1042 - PhidgetSpatial 3/3/3 instead.

The 1044 could be used to:

  • Provide spatial data for a remote control vehicle
  • Capture motion input data for research purposes
  • Gather motion statistics for moving objects

Use the following program to correct for magnetic errors in your application:

1044 Panel.jpg

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

  • Serial number: allows you to differentiate between similar Phidgets.
  • Channel: allows you to differentiate between similar objects on a Phidget.
  • Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.

The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.


Double-click on the Accelerometer object in order to run the example:

  • An extremely accurate timestamp is also reported with the Gauss values.


Double-click on the Spatial object in order to run the example:

1044 Spatial Example.jpg

The Spatial example demonstrates that you can receive data from the accelerometer, gyroscope, and magnetometer all at once by using the Spatial object rather than the other three objects individually.

Finding The Addressing Information

Before you can access the device in your own code, and from our examples, you'll need to take note of the addressing parameters for your Phidget. These will indicate how the Phidget is physically connected to your application. For simplicity, these parameters can be found by clicking the button at the top of the Control Panel example for that Phidget.

The locate Phidget button is found in the device information box

In the Addressing Information window, the section above the line displays information you will need to connect to your Phidget from any application. In particular, note the Channel Class field as this will be the API you will need to use with your Phidget, and the type of example you should use to get started with it. The section below the line provides information about the network the Phidget is connected on if it is attached remotely. Keep track of these parameters moving forward, as you will need them once you start running our examples or your own code.

All the information you need to address your Phidget

Using Your Own Program

You are now ready to start writing your own code for the device. The best way to do that is to start from our examples:

This Phidget is compatible with the following examples:

Once you have your example, you will need to follow the instructions on the page for your programming language to get it running. To find these instructions, select your programming language from the Software Overview page.

Technical Details

High Resolution Mode

When the 1044 measures an acceleration value with magnitude less than 2g, it will acquire its data from a higher precision accelerometer chip. For these measurements, the average white noise on each axis will be reduced by approximately a factor of ten, and the resolution will increase from 976 μg to 76 μg. Likewise, when the gyroscope measures a rotation value with magnitude less than 300 °/s on the Z-axis or 400 °/s on the X or Y-axis, the noise per axis will be approximately six times lower, and the resolution will increase from 0.07 °/s to 0.02 °/s. The transition from normal to high precision or vice-versa is seamless, with no additional code or equations needed.

3-Axis Accelerometer

The 1044 has a 3-Axis accelerometer that can measure ±8 g's (±78 m/s2) per axis. It will measure both dynamic acceleration (change in velocity) and static acceleration (gravity vector).


1041 0 Axis Diagram.jpg

When working with an accelerometer it is important to know which is the positive and negative direction on each of the axes. This can be determined by orienting the accelerometer along each axis and checking the output. The above image shows what the axis readings should be for each orientation of the 1044.

For more information on how to use the accelerometer, check the Accelerometer Primer.

3-Axis Gyroscope

For more information on the gyroscope, see the Gyroscope Primer.

3-Axis Magnetometer (Compass)

The magnetometer reports the sum of all magnetic fields acting on the 1044. The earth's magnetic field is only one source that affects this measurement. In order to get accurate bearing data from the magnetometer - (i.e. to find magnetic north as a compass) any interfering magnetic effects need to be calibrated out. For more information about calibration, see the section below, or the Compass Primer.

Any magnetic field that is stationary with respect to the 1044, and less than ± 3 Gauss, can be calibrated out of the magnetic field measurement. This includes both hard and soft iron effects caused by nearby ferrous and magnetic materials. Interfering magnetic fields that vary in strength and orientation with respect to the 1044 cannot be easily calibrated out.

Magnetic field data will become unavailable during every other sample as the compass performs internal calibrations. When this happens, the magneticField array in the SpatialData structure will either have a length of zero, or each element will equal PUNK_DBL, depending on the API being used. This needs to be handled explicitly in the event handling code to avoid erroneous program behavior. The maximum sampling rate of the compass is 125 Hz.

Magnetic Error Correction (Calibration)

In order to get numbers of useful accuracy from the 1044's compass you will need to provide calibration parameters. To make determining them easy, we distribute a program with our drivers that does this for you.

To calibrate your compass:

  • Navigate to the Phidgets installation folder on your computer. Open the 'examples' folder and find the Compass Calibrator program.


  • Select your country and city. Click 'Get Location' and then 'Compute'. A table of values will show up in an overlaid window. The value you will need is the 'Total Field' value in nT.

  • Enter the magnetic field value into the calibration program. Note that it wants the field strength in Gauss, not nT like the website gives you. 1T = 10000 Gauss so you can divide by 1x10^5 to convert to Gauss.
  • Depending on what your application is this step as well as the next step might be a bit different. If you are intending on mounting the 1044 onto a large vehicle such as a car then you should mount the 1056 securely to the vehicle in its final intended position then check the 2-axis bubble, click the 'Start' button.
  • If you are using a smaller, more easily handled vehicle such as a small robot (something you could physically pick up) you will mount the 1044 and use the 3-axis calibration instead. Click 'Start'.

  • Rotate the compass around (including whatever equipment you have mounted it to) such that the red dots being generated on screen outline as much of a full sphere (in 3-axis) as possible. This will take several minutes. Being perfect is not necessary but try to be as thorough as time permits. Once done, click stop.
  • If you are in a large vehicle, you will be aiming to fill out a disc instead of a sphere. This can be done by simply driving around for a few minutes making sure to do complete turns in the process.

  • Take the parameters displayed in the text box and use them for your compass. For example in C#:

     setCompassCorrectionParameters(0.51075, 0.18820, -0.07456, -0.02209, 1.87163, 1.87640, 2.12565, -0.04000, -0.04084, -0.03552, 0.09073, -0.04258, 0.11056);
