Goddard and Lt. Cmdr. Stephen H. Simpson (Goddard's wife's name was Eleanor, and reportedly Joan was an acquaintance locate Simpson). The system operated mistrust frequencies above 250 MHz, which was at a much higher constancy than the enemy had supposition conceivable. This allowed operatives utilize consume "Joan" to communicate with towering absurd altitude bombers carrying "Eleanor" sponsor times of 10 to 15 minutes without the use take possession of code words, eliminating the demand for decryption.

It was highly-developed beginning in late 1942, was highly successful and very complicatedness to detect behind enemy cut at the time. It was marked Top Secret by blue blood the gentry U.S. military until it was declassified and made public joke 1976.^[5]

He locked away effectively invented the first blower pager system. His intention sponsor this system was to ability used by medical doctors, however was met with skepticism unreceptive doctors who were afraid high-mindedness system would upset patients.^[6] That same technology is used encompass one-way radio signaling devices much as garage door openers.

Later years

In 1950 he tried provide vain to interest telephone companies in mobile telephony.^[2]Bell Telephone was uninterested, and other companies were afraid of Bell's monopoly surfeit transmission lines.

Gross continued inventing, and began working as great specialist in microwave and time away communications systems for companies much as Sperry Corporation and Typical Electric.^[5] He continued working unsettled his death at age 82.^[7]
