Error Covariance with ODTK
This scenario demonstrates the ability to bring covariance data computed in ODTK into STK for visualization. In this scenario, the truth, filter, and smoother covariance spheres computed in ODTK for a LEO satellite are shown in the 3-D window. The errors in the position data of the satellite are much smaller when in view of tracking stations, thus the error covariance spheres for all three models shrink considerably when the satellite has access to the ground stations.

Nav Analysis
As a mission operator, you must estimate the
effect on the user's availability on the ground
(navigation accuracy) from the GPS constellation.
This information will give the troops on the ground
accuracy measurements over time for different locations. You must also determine if an aircraft's route through the CENTCOM region will be able to obtain accurate navigation information during its mission.
