Test method

test_formationBarycenter.test_formationBarycenter(show_plots, accuracy)

Validation Test Description

This unit test verifies the formationBarycenter module. It checks the barycenter of three spacecraft using both cartesian coordinates and orbital elements weighted averaging.

Test Parameters

The test parameters used are the following:

Parameters:

accuracy (float) – absolute accuracy value used in the validation tests

Description of Variables Being Tested

In this file we are checking the values of the variables

• barycenter

• barycenterVelocity

• barycenterC

• barycenterVelocityC

which represent the center of mass position and velocity vectors. The variables ending in C are pulled from the C-wrapped navigation output message, whereas the other two come from the usual C++ message. All these variables are compared to trueBarycenter and trueBarycenterVelocity, which contain their true values.

As stated, both the C and C++ wrapped message outputs are checked.
