“Celestial (Stellar) Navigation” Speaker – Allen Edwards

Member/Speaker Allen Edwards spoke on the continuing use of stellar navigation as applied to Space Navigation – A variation on terrestrial celestial navigation was used to help orient the Apollo spacecraft en route to and from the Moon. To this day, space missions such as the Mars Exploration Rover use star trackers to determine the attitude of the spacecraft. Allen presented an INS unit and Sextant for show and tell experience. About the speaker – Club member Allen has a BSEE degree from Univ. of Illionois and a MBA from the Univ. ofPhoenix. He is president of the StellarNav LLC.
