    The National Institute of Aeronautics and Space (Indonesian: Lembaga Penerbangan dan Antariksa Nasional, LAPAN) was the Indonesian government's space agency.It was established on 27 November 1963, by former Indonesian president Sukarno, after one year's existence of a previous, informal space agency organization.

    en.wikipedia.org/wiki/Space-based_radar

    ORS-2. Space-based radar or spaceborne radar is a radar operating in outer space; orbiting radar is a radar in orbit and Earth orbiting radar is a radar in geocentric orbit.A number of Earth-observing satellites, such as RADARSAT, have employed synthetic aperture radar (SAR) to obtain terrain and land-cover information about the Earth.

    en.wikipedia.org/wiki/US-A

    The US-A programme was responsible for orbiting a total of 33 nuclear reactors, 31 of them BES-5 types with a capacity of providing about two kilowatts of power for the radar unit. In addition, in 1987 the Soviets launched two larger TOPAZ nuclear reactors (six kilowatts) in Kosmos satellites ( Kosmos 1818 and Kosmos 1867 ) which were each ...

    By 1981, the plan was for the spacecraft to launch in 1987 and to use aerobraking to circularize its orbit, whereupon it would be able to generate radar coverage of the entire planet over a period of 126 days. Data transmission rates were 1 Mbit per second, matching the imaging and recording speed.

    The radar mile is the time it takes for a radar pulse to travel one nautical mile, reflect off a target, and return to the radar antenna. Since a nautical mile is defined as 1,852 m, then dividing this distance by the speed of light (299,792,458 m/s), and then multiplying the result by 2 yields a result of 12.36 μs in duration.

  7. Artificial satellites in retrograde orbit - Wikipedia

    en.wikipedia.org/wiki/Artificial_satellites_in...

    The United States launched two Future Imagery Architecture (FIA) radar satellites into 122° inclined retrograde orbits in 2010 and 2012. The use of a retrograde orbit suggest that these satellites use synthetic aperture radar. [3] Earth-observing satellites may also be launched into a Sun-synchronous orbit, which is slightly retrograde. [8]

    The Visible Infrared Imaging Radiometer Suite (VIIRS) is a sensor designed and manufactured by the Raytheon Company on board the polar-orbiting Suomi National Polar-orbiting Partnership (Suomi NPP), NOAA-20, and NOAA-21 weather satellites. [1] VIIRS is one of five key instruments onboard Suomi NPP, launched on October 28, 2011. [2]
