SUMMARY
The discussion centers on the integration of a velocity random walk into a Kalman filter measurement equation, specifically the term "-g + v", where g is acceleration in m/s² and v is velocity random walk expressed in m/s/sqrt(hr). The primary issue identified is the incompatibility of units between acceleration and the given velocity random walk, indicating a potential error in the formulation of the equation. The suggestion is made to reconsider the placement of the random walk process, advocating for its inclusion in the state propagation equation instead of the measurement equation.
