Function Documentation

MatXd lupnt::ProcessNoiseClock(ClockModel cmodel, int n_clk, Real dt)

Build the clock-state process-noise covariance block for a given clock model and time step, via ClockDynamics::TwoStateNoise/ThreeStateNoise.

Called by ProcessNoisePosVelClock to form the clock block of the combined position/velocity/clock process-noise matrix Q.

Parameters:

• clock_model – Clock noise model (e.g. OCXO, USO, CSAC, RAFS)

• n_clk – Clock state dimension: 2 (bias, drift) or 3 (bias, drift, drift-rate)

• dt – Time step [s]

Returns:

Clock process noise covariance, size [n_clk x n_clk]
