Upon very close examination of navigational data, the spacecraft were found to be slowing slightly more than expected.

She broke into a smile when she saw the last piece of navigational data.

The crew of each flight helped by supplying the navigational data needed for the comparison with theory.

"Look at this code and tell me why the computer isn't accepting navigational data," the chief engineer said.
