The latest feature for #FormaK: a reference implementation of a #strapdown #IMU!

Goals for the reference model:

1. Provide an example for what a more complicated model looks like in FormaK
2. Provide a composable implementation of a strapdown IMU that can be built into other models

The learnings from this model will also inspire some new work coming soon!

As always, the reference model can be compiled into #Python and #Cpp
