Argos (satellite System)
Argos is a global satellite-based system that collects, processes, and Dissemination, disseminates (spreads, distributes) environmental data from fixed and mobile platforms around the world. The worldwide tracking and environmental monitoring system is the results froFranco-American cooperation.In addition to satellite data collection, the main feature of the Argos system is its to ability to Geopositioning, geographically locate the data source from any location on Earth using the Doppler effect; which refers to the apparent change in the wavelength due to relative motion between its source and observer. Argos is operated by CLS/Argos, based in Toulouse, France, and its United States subsidiary, CLS America. History and utilization Argos was established in 1978 and has provided data to environmental research and protection groups.

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 Precession, 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 satellite, imaging, reconnaissance satellite, 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, ... [...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 and the 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. The second attempt, 5 February 2009, was scrubbed after the failure of a payload fairing air conditioning compressor, which is also part of the ground support equipment at the launch pad.

Geographic Coordinates
A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. It is the simplest, oldest, and most widely used type 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 ...

List Of Electron Launches
Electron is a two-stage small-lift launch vehicle built and operated by Rocket Lab. The rocket has been launched to orbit 64 times with 60 successes and four failures. A suborbital version of the rocket, HASTE, has been successfully launched three times. The first flight, known as "It's a Test", launched on 25 May 2017. The mission failed due to a glitch in communication equipment on the ground. Successful follow-on missions, including "Still Testing", "It's Business Time" and "This One's For Pickering", delivered multiple small payloads to low Earth orbit. Flight 26 was the first Electron flight to attempt a full catch recovery using a mid-air helicopter catch. "Scout's Arrow" was the first suborbital launch of the rocket. In July 2019, Rocket Lab expected to have launches every two weeks in 2020. In June 2020, with a new Electron launch vehicle built every 18 days, Rocket Lab was planning to deliver monthly launches for the remainder of 2020 and into 2021, including the comp ...

Rocket Lab Electron
Electron is a two-stage, partially reusable launch vehicle, reusable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary. Servicing the commercial small satellite launch market, it is the third most launched small-lift launch vehicle in history. Its Rutherford (rocket engine), Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket. Electron is often flown with a kickstage or Rocket Lab's Rocket Lab Photon, Photon spacecraft. Although the rocket was designed to be expendable launch system, expendable, Rocket Lab has recovered the first stage twice and is working towards the capability of Reusable launch system, reusing the booster. The List of Electron first stages, Flight 26 (F26) booster has featured the first helicopter catch recovery attempt. Rocket Lab has, however, abandoned the idea of catching Electron.

Metop
MetOp (Meteorological Operational satellite) is a series of three polar-orbiting meteorological satellites developed by the European Space Agency (ESA) and operated by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). The satellites form the space segment component of the overall EUMETSAT Polar System (EPS), which in turn is the European half of the EUMETSAT / NOAA Initial Joint Polar System (IJPS). The satellites carry a payload comprising 11 scientific instruments and two which support Cospas-Sarsat Search and Rescue services. In order to provide data continuity between MetOp and NOAA Polar Operational Environmental Satellites (POES), several instruments are carried on both fleets of satellites. MetOp-A, launched on 19 October 2006, was Europe's first polar orbiting satellite used for operational meteorology. With respect to its primary mission of providing data for Numerical Weather Prediction, studies have shown that ''MetOp-A'' data ...

European Organisation For The Exploitation Of Meteorological Satellites
The European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) is an intergovernmental organisation created through an international convention agreed by a current total of 30 European Member States. EUMETSAT's primary objective is to establish, maintain and exploit European systems of operational meteorological satellites. EUMETSAT is responsible for the launch and operation of the satellites and for delivering satellite data to end-users as well as contributing to the operational monitoring of climate and the detection of global climate changes. The activities of EUMETSAT contribute to a global meteorological satellite observing system coordinated with other space-faring states. Satellite observations are an essential input to numerical weather prediction systems and also assist the human forecaster in the diagnosis of potentially hazardous weather developments.
