Syntax

[res,resCov] = residualaltimeter(FUSE,altimeterReadings,altimeterReadingsCovariance)

Description

[res,resCov] = residualaltimeter(FUSE,altimeterReadings,altimeterReadingsCovariance) computes the residual, res, and the innovation covariance, resCov, based on the altimeter readings and the corresponding covariance.

Open Live Script

Create an ahrs10filter object and display its state.

filter = ahrs10filter;
disp(filter.State')
    1.0000         0         0         0         0         0         0         0         0         0         0         0   27.5550   -2.4169  -16.0849         0         0         0

Define altimeter data with a reading and a covariance. Obtain the residual of the data.

magReading = 50;
magCovariance = 4;
[res,resCovariance] = residualaltimeter(filter,magReading,magCovariance)
res = 
-50

resCovariance = 
4.0000
