Gravimetric interferences are phenomena in space that can make plotting a course rather difficult.

Navigating through a globular cluster like the Amargosa Diaspora can be complicated by gravimetric interferences. When the USS Enterprise-D was examining the Amargosa Diaspora, Commander William T. Riker assisted Ensign Sariel Rager in plotting a course through the clusters and showed her how to compensate for gravimetric interference. (TNG: "Schisms")
