In all cases (both CLI and GUI), the least significant digits are minutes, not decimal degrees. Calibrate your compass according to compass calibration SBASWhen using a UBLOX GPS the SBAS mode can be configured using gps_sbas_mode.The default is AUTO.ValueRegion AUTO Global EGNOS Europe WAAS...
The heading accuracy is within 2 degrees depending on how well the compass has been calibrated. Without tilt compensation the compass headings vary significantly ... sometimes by as much as 100 degrees. When stabilised, the tilted compass headings only vary by one or two degrees ... the improv...
Calibration Procedure For the HMR3400, one complete turn in a level plane is the starting point to expose the XY sensors to all headings to compute the calibration offsets. Since the compass collects data at a 8 samples per second rate, a sample per degree of rotation or slower is a ...
Note that in addition to restarting the compass, I reset the report interval to 400 ms to ensure consistent behavior. Toggling Between Numeric and Alpha HeadingsThe code that toggles between alpha and numeric headings is controlled by a single Boolean variable named Alphabetic that’...

4. Rotate the aircraft to a known West heading. Note how many degrees off West the compass reads. Adjust the E-W adjusting screw to remove one-half of the error. 5. Rotate the aircraft through the N,S,E,W headings again, confirming that the errors for North and South are the same,...
The magnetic and true headings are correct when the iPhone device is held like a traditional compass. In portrait mode, if the user rotates the device, then the heading readings will still be in this frame of reference. Even though the user has not changed the direction he is facing, the...
Compass Headings Normally when we’re using a compass, we don’t want a 3D vector aligned with Earth’s magnetic field. Much more useful would be a 2D vector that’s tangent to Earth’s surface. As you probably know, Earth’s magnetic field does not coincide with the axis on which Ear...
