Failing Normalization Assertion on Sun Vector Measurement

[kylekrol]

Not really sure what's going on here but the command that's failing is:

python -m psim -s 100000 -p fc/attitude -ps 50 -c sensors/base,truth/base,truth/deployment AttitudeEstimatorTestGnc

and results in:

...
[11:50:16 PM INFO] psim.plugins.stop: 40% of the maximum allowable steps taken.
python: src/gnc/attitude_estimator.cpp:510: void gnc::attitude_estimator_update(gnc::AttitudeEstimatorState&, const gnc::AttitudeEstimatorData&, gnc::AttitudeEstimate&): Assertion `std::abs(1.0f - lin::fro(data.s_body)) < 1.0e-2f' failed.
zsh: abort (core dumped)  python -m psim -s 100000 -p fc/attitude -ps 50 -c  AttitudeEstimatorTestGnc

The modelling eclipse was disabled in the configuration files so the sun vector shouldn't be nan.
