Carbonara Labs Inc. is part of Carp Industries Corp. Carbonara has been building the Sextant type Stadimeter for over 40 years.  The Stadimeter, partnumber 9240-035, NSN 6605-01-168-8508 is used on Navy vessels for traditional celestial navigation. Mark 5 Mod 1 consists of a metal frame, similar to that of a sextant, upon which are mounted a telescope, horizon mirror, radius arm, index arm and index mirror. The known height of an object is set by moving the radius arm along the height scale. By rotating the micrometer drum, the top of the reflected image is brought into coincidence or alignment with the bottom of the real image. The distance of the object, in yards, is then read directly on the micrometer drum. Today they are still required on each vessel and are used during testing and training functions.  We have a large inventory of spares for the repair of as well as manufacturing.
