insfilter

Create inertial navigation filter

Syntax

filter = insfilter

filter = insfilter('ReferenceFrame',RF)

Description

filter = insfilter returns an insfilterMARG inertial navigation filter object that estimates pose based on accelerometer, gyroscope, GPS, and magnetometer measurements. See insfilterMARG for more details.

filter = insfilter('ReferenceFrame',RF) returns an insfilterMARG inertial navigation filter object that estimates pose relative to a reference frame specified by RF. Specify RF as 'NED' (North-East-Down) or 'ENU' (East-North-Up). The default value is 'NED'. See insfilterMARG for more details.

Examples

Create Default INS Filter

The default INS filter is the insfilterMARG object. Call insfilter with no input arguments to create the default INS filter.

filter = insfilter

filter = 
  insfilterMARG with properties:

        IMUSampleRate: 100               Hz         
    ReferenceLocation: [0 0 0]           [deg deg m]
                State: [22x1 double]                
      StateCovariance: [22x22 double]
