Argos (satellite System)
Argos is a global satellite-based system that collects, processes, and disseminates environmental data from fixed and mobile platforms around the world. The worldwide tracking and environmental monitoring system results from Franco-American cooperation. Besides satellite data collection, the Argos system's main feature is the ability to geographically locate the data source from any location on Earth using the Doppler effect. History and utilization Argos was established in 1978 and has provided data to environmental research and protection groups that was previously unobtainable. Many remote automatic weather stations report via Argos. Argos is a component of many global research programs including: Tropical Ocean-Global Atmosphere program (TOGA), Tagging of Pacific Pelagics (TOPP), World Ocean Circulation Experiment (WOCE), Argo. There are 22,000 active transmitters (8,000 of which are used in animal tracking) in over 100 countries. Since the late 1980s, Argos transmi ...

Sun-synchronous Orbit
A Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet's surface at the same local mean solar time. More technically, it is an orbit arranged so that it precesses through one complete revolution each year, so it always maintains the same relationship with the Sun. Applications A Sun-synchronous orbit is useful for imaging, reconnaissance, and weather satellites, because every time that the satellite is overhead, the surface illumination angle on the planet underneath it is nearly the same. This consistent lighting is a useful characteristic for satellites that image the Earth's surface in visible or infrared wavelengths, such as weather and spy satellites, and for other remote-sensing satellites, such as those carrying ocean and atmospheric remote-sensing instruments that require sunlight. For example, a satellite in Sun-synchronous orbit might ascend acros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NOAA-19
NOAA-19, known as NOAA-N' (NOAA-N Prime) before launch, is the last of the American National Oceanic and Atmospheric Administration (NOAA) series of weather satellites. NOAA-19 was launched on 6 February 2009. NOAA-19 is in an afternoon Sun-synchronous orbit and is intended to replace NOAA-18 as the prime afternoon spacecraft. Launch On 4 November 2008, NASA announced that the satellite had arrived at Vandenberg aboard a Lockheed C-5 Galaxy military transport aircraft. Installation of the payload fairing took place 27 January 2009; second stage propellant was loaded on 31 January 2009. Several attempts were made to conduct the launch. The first attempt, 4 February 2009, was scrubbed after a failure was detected in a launch pad gaseous nitrogen pressurization system.

Geographic Coordinates
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century ...

CubeSat
A CubeSat is a class of miniaturized satellite based around a form factor consisting of cubes. CubeSats have a mass of no more than per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are put into orbit by deployers on the International Space Station, or launched as secondary payloads on a launch vehicle. , more than 1,600 CubeSats have been launched. In 1999, California Polytechnic State University (Cal Poly) professor Jordi Puig-Suari and Bob Twiggs, a professor at Stanford University Space Systems Development Laboratory, developed the CubeSat specifications to promote and develop the skills necessary for the design, manufacture, and testing of small satellites intended for low Earth orbit (LEO) that perform a number of scientific research functions and explore new space technologies. Academia accounted for the majority of CubeSat launches until 2013, when more than half of launches were for non-academic purposes, ...
