// @DisplayName: Magnetometer default fusion mode // @DisplayName: Magnetometer default fusion mode
// @Description: This determines when the filter will use the 3-axis magnetometer fusion model that estimates both earth and body fixed magnetic field states, when it will use a simpler magnetic heading fusion model that does not use magnetic field states and when it will use an alternative method of yaw determination to the magnetometer. The 3-axis magnetometer fusion is only suitable for use when the external magnetic field environment is stable. EK2_MAG_CAL = 0 uses heading fusion on ground, 3-axis fusion in-flight, and is the default setting for Plane users. EK2_MAG_CAL = 1 uses 3-axis fusion only when manoeuvring. EK2_MAG_CAL = 2 uses heading fusion at all times, is recommended if the external magnetic field is varying and is the default for rovers. EK2_MAG_CAL = 3 uses heading fusion on the ground and 3-axis fusion after the first in-air field and yaw reset has completed, and is the default for copters. EK2_MAG_CAL = 4 uses 3-axis fusion at all times. NOTE: The fusion mode can be forced to 2 for specific EKF cores using the EK2_MAG_MASK parameter. NOTE: limited operation without a magnetometer or any other yaw sensor is possible by setting all COMPASS1_USE, COMPASS2_USE, COMPASS3_USE, etc parameters to 0 with COMPASS_ENABLE set to 1. If this is done, the EK2_GSF_RUN and EK2_GSF_USE masks must be set to the same as EK2_IMU_MASK. // @Description: This determines when the filter will use the 3-axis magnetometer fusion model that estimates both earth and body fixed magnetic field states, when it will use a simpler magnetic heading fusion model that does not use magnetic field states and when it will use an alternative method of yaw determination to the magnetometer.
