Among the documents at this site is manual AN 08-25-17: "INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS, CELESTIAL NAVIGATION TRAINER AN-2554-1", May 20, 1943. https://digitalcollections.museumofflight.org/items/browse?collection=882&page=6 "The AN-2554-1 Trainer is a synthetic training device making available to pilots, navigators, bombardiers, and radio operators simulated flying conditions in daylight, darkness, or both in sequence, depending upon the type and length of problem that is to be used." The four students sit in a fuselage capable of unlimited rotation in heading and limited rotation in pitch and roll. A turbulence system can produce erratic motion. Incandescent lamps on a rotating dome simulate the sky. A few stars are simulated by collimators so they can be shot by sextant from the astrodome at the navigator's station. -- Paul Hirose sofajpl.com

What is NavList?

NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

NavList is more than an online community... more about that another day.
