thumb|220px|''Curiosity's'' self-portrait shows the deck of the rover as viewed from the NavCams. Navcam, short for navigational camera, is a type of camera found on certain robotic rovers or spacecraft used for navigation without interfering with scientific instruments. Navcams typically take wide angle photographs that are used to plan the next moves of the vehicle or object tracking.

It has a filter wheel assembly that enables it to view different wavelengths of light and the pair of Pancams are mounted beside two NavCams on the MER camera bar assembly.

It is used to calibrate the Pancam cameras of the Mars landers. MarsDials were placed on the Spirit and Opportunity Mars rovers, inscribed with the words "Two worlds, One sun" and the word "Mars" in 22 languages. The MarsDial can function as a gnomon, the stick or other vertical part of a sundial. The length and direction of the shadow cast by the stick allows observers to calculate the time of day. The sundial can also be used to tell which way
