Setting up an OD System
|Top Previous Next|
FreeFlyer contains several different objects that have at least one property that can be estimated. For information on the configuration of these objects, see:
The estimator forms the core of any OD process. It contains references to the objects to be estimated (as listed above) as well as references to all tracking data to be processed. FreeFlyer supports four kinds of estimators: Extended Kalman Filter, Square Root Information Filter, Unscented Kalman Filter, and Batch Least Squares. For more information, see:
After choosing your estimation technique, there are a few other areas that require some configuration. Additional items that you may need to set up include:
Once you have completed the initial setup of your OD system, continue to the Tracking Data and Performing State Estimation sections for information on how to use your configuration to generate results.
