The second and the third subframes contain the ephemeris - the precise orbit for the satellite.

Astronomers used them for mapping the positions and precise orbits of solar objects.

These inertial navigation systems guide the rockets in their trajectory, thus helping them to put the satellites in precise orbits.

These inertial navigation systems guide the rockets through their trajectory to put the satellite in precise orbits.

An explosion rippled nearby, disturbing the precise orbits of debris in the rings.

Knowing this chord and the foreground object's size, a more precise orbit for the object can be determined.

Now, however, a meteorite has been found in southern Germany, and a precise orbit has been determined for it.

TheHellsbreath will look, feel, and sound just like the crater with which we are in a very precise and matching orbit.

An unusual feature of the mission is that it only had a one-second launch window due to the precise orbit required by the experiment.

However, this asteroid was not observed beyond its initial appearance and a precise orbit could not be calculated.
