Tracking
The entry system will be tracked and targeted utilizing a combination of Doppler radar and very long baseline interferometry. This data is processed by a high-resolution orbital model that utilizes high-precision ephemeris to predict spacecraft location and trajectory.
Upon launch, tracking will commence at the Algonquin Radio Observatory. After orbital injection, the spacecraft will be contacted periodically to obtain system status and to determine trajectory. As the package reaches the Matrian thermosphere continuous tracking will commence in order to verify mechanism deployment during descent.

Famous quotes containing the word tracking:
“Such is the art of writing as Dreiser understands it and practices it—an endless piling up of minutiae, an almost ferocious tracking down of ions, electrons and molecules, an unshakable determination to tell it all. One is amazed by the mole-like diligence of the man, and no less by his exasperating disregard for the ease of his readers.”
—H.L. (Henry Lewis)
