ODTK Background

ODTK 6.3.0 is built upon the same verified astrodynamics functions and coordinate conversions as STK and its modules. ODTK 6.3.0 is a matched set of modules, designed to provide orbit determination and analysis support for the entire life-cycle of satellite tracking systems. All phases of systems design can be supported with simulated tracking data, Monte Carlo analyses, and covariance analyses. ODTK 6.3.0 can produce results for satellite orbit parameters by processing one satellite at a time or multiple satellites simultaneously. ODTK is a stand-alone product, not an add-on module to STK.

The main products in this suite are a tracking data simulator, a state-of-the-art optimal sequential filter and a matched optimal sequential smoother. The sequential filter is designed to provide capabilities in support of routine satellite operations, including orbit determination, ephemeris prediction, and bias and maneuver/thruster calibration. The sequential filter produces a realistic covariance for system performance analyses, tasking optimization, and calculation of the probability of collision (in conjunction with STK/CAT). The optimal smoother provides high accuracy post-fit ephemerides in support of mission data products.

Particular care has been taken to ensure that regression tests to ODTK 5 are satisfied, that ODTK 5 scenarios will load and run in ODTK 6.3.0, and that ODTK 5 restart files will initialize in ODTK 6.3.0.
