You can configure the Orbit Determination Properties for any GroundStation through FreeFlyer script or the Object Browser. There are two ways to navigate to the "Station Location" page under the Orbit Determination section of the GroundStation object editor:
1.Open the desired GroundStation's editor and navigate to the Station Location page under Orbit Determination 2.Highlight the desired GroundStation on the "Objects to Process" page of a Kalman Filter, Square Root Information Filter, Unscented Kalman Filter, or Batch Least Squares object editor and click the "Modify GroundStation Estimation Options" button |
From this page, you can configure any of these options:
•The GroundStation properties that you want to ignore, estimate, or consider oIgnore: Leave the property out of the estimated state. oEstimate: Include the property in the estimated state and allow the estimator to update its value. oConsider: Include the property in the estimated state, but do NOT allow the estimator to update its value. This means that the property gets included in the covariance, but is not directly estimated. •The A Priori Bias, Sigma, and Process Noise Rate for each of the properties |
GroundStation OD Properties
To define the GroundStation properties that you want to estimate or consider via FreeFlyer script, you will access the GroundStation's OD properties, as shown in the example below:
// Properties to Estimate Canberra.OD.HeightBias.ProcessAction = 1; Canberra.OD.LatitudeBias.ProcessAction = 1; Canberra.OD.LongitudeBias.ProcessAction = 1; |
For information on configuring a GroundStation's GroundAntenna, see GroundAntenna Setup.
Once the GroundStation has been configured, it can be used as an observing object or object being observed when simulating tracking data or including tracking data in an estimation process.
