A diagram of a typical nautical sextant, a tool used in celestial navigation to measure the angle between two objects viewed by means of its optical sight. Celestial navigation, also known as astronavigation, is the practice of position fixing using stars and other celestial bodies that enables a navigator to accurately determine their actual current physical position in space or on the ...
P78-1 or Solwind was a United States satellite launched aboard an Atlas F rocket from Vandenberg Air Force Base in California on February 24, 1979.

[1] The missile would climb at subsonic speed to its operating altitude, then conduct a supersonic dash to the target area, guided by a celestial navigation system. [1]
The Royal Air Force (RAF) adopted astronavigation techniques into standard navigator training during the late 1930s, both the methods used and the design of the sextant were adapted to better suit the aviation environment, while many aircraft ordered by the service would be furnished with astrodomes to enable navigators to use this technique.
The Joint Navigation Warfare Center plans, tasks, integrates, provides C2, and supports integrated Navigation Warfare (NAVWAR) worldwide. Navigation warfare means the use of the "Air Force Global Positioning System satellite navigation system by the Department of Defense and its allies, and attempts to disrupt the system by adversaries."

In March 2017, the contractor rephased its OCX delivery schedule so that Block 2 will now be delivered to the Air Force concurrently with Block 1. [71] In July 2017, an additional nine months delay to the schedule was announced. According to the July 2017 program schedule, OCX will be delivered to the U.S. Air Force in April 2022. [47]
