NRL pioneered the study of the sun Ultraviolet and X-Ray spectrum and continues to contribute to the field with satellites like Coriolis launched in 2003. NRL is also responsible for the Tactical Satellite Program with spacecraft launched in 2006, 2009 and 2011.
The next logical step was the construction of a long north-south fence that the satellite would pass through on almost every orbit. But the Vanguard program could not financially support a long chain of paired stations; besides, further thought soon showed that complete orbital data could be computed from angular (interferometric) tracking alone.
The director was John P. Hagen (1908–1990), an astronomer who in 1958 would become the assistant director of space flight development with the formation of NASA. [8] After a delay due to the NRL changing the shape of the satellite from a conical shape, [9] the initial 1.4 kg (3.1 lb) spherical Vanguard satellites were built at the NRL, and ...

Many improvements were made to provide a more compact and efficient monopulse antenna feed and lobe comparison waveguide circuitry, such that monopulse tracking radar became the generally accepted tracking radar system for military and civilian agencies, such as NASA and the FAA. The NRL's work on monopulse radars eventually led to the AN/FPS ...
The POPPY program was a continuation within NRO's Program C of the Naval Research Laboratory's (NRL) Galactic Radiation and Background (GRAB) ELINT program, also known as Tattletale. The National Security Agency was given the responsibility of collecting, interpreting, and reporting the signals intercepted.
NRL is the corporate research laboratory for the Navy and Marine Corps and conducts a broad program of scientific research, technology and advanced development. It has a prestigious history, including the development of the first U.S. radar system, [ 10 ] synthetic lubricants (for modern gas turbine engines), over-the-horizon radar , [ 11 ] the ...
Galactic Radiation and Background (GRAB) was the first successful United States orbital surveillance program, comprising a series of five Naval Research Laboratory electronic surveillance and solar astronomy satellites, launched from 1960 to 1962. Though only two of the five satellites made it into orbit, they returned a wealth of information ...
