Estimation Techniques

Top Previous Next

When working with FreeFlyer's Orbit Determination system, there are four available estimation techniques: Batch Least Squares, the Extended Kalman Filter, the Square Root Information Filter, and the Unscented Kalman Filter. The first steps to creating your OD system are to choose one of these techniques and configure its basic options. You can learn more about this by following these links:

•Setting up a Batch Least Squares Estimator

•Setting up an Extended Kalman Filter

•Setting up a Square Root Information Filter

•Setting up an Unscented Kalman Filter

•Setting up a Smoother

Once this initial setup is complete, continue configuring your OD system by:

•Defining the A Priori States

•Defining the Measurement Model

•Defining Thrust Events

•Defining the Properties to Estimate

•Including Tracking Data
