Radio Sextant Developed for Submarines
Norwood, Mass.—An electronic sextant capable of correcting inertial navigation systems of Polaris missile submarines is nearing completion here in the laboratories of American Standard, Military Products Division. Essentially a radio telescope designed for underseas operation, the sextant will lock-in on X-band radio emission from the moon, the sun or ultimately other stars besides the sun and will provide corrections for errors due to gyro drift in the ship’s inertial system. The combination—ship’s inertial navigation system and the electronic sextant —will provide Polaris submarines with an accurate, all-weather navigational capability.
