Investigation of Long-Term Storage and Reverse Link Methods for the 5-Inch SALGP Data Link.

摘要

The 5-in. guided projectile must be programmed with certain flight data prior to launch. These data must be stored in the projectile for up to 5 min without power connections. Two methods of accomplishing this are discussed: (1) A nonvolatile metal nitride oxide silicon memory and (2) a complementary metal oxide semiconductor memory driven by energy stored on a capacitor. It is also desirable to check the accuracy of the message sent. A method of reading the message back by varying the impedance of the secondary coil is discussed. (Author)
