GOE.....U.S., satellite, see GOES.
GOES.....U.S., satellite, observation. GEOSTATIONARY OPERATIONAL ENVIRONMENTAL SATELLITE series, successor to the SYNCHRONOUS METEOROLOGICAL SATELLITE (SMS) program of the National Oceanographic and Atmospheric Administration (NOAA). Designation changed from Letter to number after being placed in GEO. Launched from the ETR and placed into GEO.
Based upon the success of the SMS, NOAA launched a new series of weather satellites placed in a geostationary orbits, and named Geostationary Operational Environment Satellite (GOES). The Objectives were to sense meteorological conditions from a fixed location above the Earth (geostationary orbit, 23,000 mile orbit) and provide this data to operational forecasters and private interests on the ground. GOES satellites are providing the weather pictures you see and the television, in newspapers, and on the internet.
GOES 1 was nearly identical to the SMS satellites both in size and operational cpability. GOES 1 was placed in geostationary orbit over the Indian Ocean. With the two SMS and GOES 1 satellites operating in orbit, NOAA was able to view the weather over 60% of the Earth, including everything between 60 degrees north and 60 degrees south latitude. GOES 1 was deactivated on 7 March 1985. GOES 2 was similar to GOES 1 and operated from 1975 to 1993, and replaced SMS 1. GOES 3 was similar to GOES 1 and operated from 1978 to 1993.
GOES 4 was larger than GOES 1 through 3. It was 85 inches (2.16 m) in diameter, 138 inches (3.51 m)long, and weighed 874 lbs. (397) It contained:
- the VAS (Visible Infrared Spin Scan Radiometer (VISSR) Atmospheric Sounder) and its sunshade. This instrument provided both day and night imagery of cloud conditions as well as temperature and moisture profiles. It was the first geostationary satellite to provide continuous vertical profiles of the atmospheric temperature and moisture.
- WEFAX, which used facsimile transmission of processed images and weather maps to WEFAX field stations
- Space Environment Monitor (SEM), similar to those on the NOAA satellites, and
- Data Collection System (DCS) similar to those on the NOAA satellites.
GOES 4 operated from 1980 to 1988.
GOES 5 was nearly identical to GOES 4. It operated from 1981 to 1990. GOES 6 was nearly identical to GOES 4 and operated from 1983 to 1989. During this time period, NOAA made a name change in the operational GOES satellite series. GOES 6, placed over the Pacific (136o W) was renamed GOES WEST. GOES G had the unfortunate experience of being on a Delta rocket that was struck by lightening shortly after being launched and was destroyed by the range safety officer, bummer!
GOES 7 was nearly identical to GOES 4 but has had an interesting life. GOES 7 was renamed to GOES-EAST, once in orbit over the Atlantic Ocean (75o W). When GOES 6 (GOES WEST) imager failed, GOES EAST (GOES 7) was moved to cover the U.S. west coast (112o W). GOES 7 spin is now no longer stable, and has developed a “figure 8" orbit at 105o W. It is used for satellite communications.
GOES 8 was a big change in weather satellites in that it provided a significant improvement over the previous GOES satellites. This helps explain why it was launched 7 years after GOES 7. The GOES 8 satellite was derived from Space System/Loral's communications satellites FS-1300 bus, providing a 3-axis stabilized design. The main body of the satellite is a 78 inch cube (2-meter), with a deployed length of 88 ft (27 meters), and weighs 4600 pounds (2100 kg). It required an Atlas 1/Centaur launch vehicle to place it in the proper orbit. The GOES 8 system is currently performing the following basic functions:
- Acquisition, processing, and dissemination of imaging and sounding data;
- The sounded measures the atmosphere as many layers for temperature, moisture content, and ozone distribution.
- flexible scan, offers small-scale area imaging that lets meteorologists take pictures of local weather trouble spots. This allows them to improve short-term forecasts over local areas
- simultaneous and independent imaging and sounding, which allows weather forecasters to use multiple measurements of weather phenomena to increase the accuracy of their forecasts.
- acquisition and dissemination of Space Environment Monitor (SEM) data;
- reception and relay of data from ground-based Data Collection Platforms (DCPs)
- Search and Rescue Satellite Aided Tracking (SARSAT) system which relays distress signals from people, aircraft, or marine vessels to the search and rescue ground stations.
The GOES 8 spacecraft is operational as GOES-EAST at 75o W, and is still providing clear imagery.
GOES 9 was similar to GOES 8, but had many small improvements to correct problems with GOES I/8. GOES 9 was located at 135o W and was known as GOES-WEST. However, GOES 9 had a problem the earlier satellites did not have, it was not as reliable as GOES 8. GOES 9 was deactivated 3 years after launch due to failing bearings in the momentum wheels (part of the satellite stabilization system).
GOES 10 is similar to GOES 9, but has demonstrated greatly improved reliability. GOES 10 replaced GOES 9, and is known as GOES WEST, (135o W). GOES 11 at 4900 lbs. (2217 kg) is similar to GOES 10 but is in inorbit storage waiting to replace GOES 8. GOES 12 is similar to GOES 11, is in inorbit storage. GOES 12 carries and additional instrument:
an X-ray imager providing an X-ray picture of the solar disk.
The GOES 8 (I) through 12 (M) are also known as GOES NEXT, for the next generation of GOES satellites. Plans include development and production of GOES satellites up through GOES Q, with GOES N and O to be built by Boeing (Formally Hughes). The plans include launching a GOES satellite about every two years, through 2006.

gravity.....Orbital parameter. A mutual physical force attracting two bodies. See Newtons Law of Universal Gravitation. See also Planet.
gravity assist orbit.....Hyperbolic orbits in which the spacecraft is sent close to a planet or other large solar system object in order to use gravity to change the speed or direction of the spacecraft. This action conserves fuel. The planet's/moon's angular momentum is used to change the trajectory of a spacecraft. e.g. VOYAGER 2, was launched toward Jupiter using a standard Hohman transfer orbit. VOYAGER 2 passed behind Jupiter. When VOYAGER 2 came into Jupiter's gravitational influence, VOYAGER 2 fell toward Jupiter, increasing its speed toward a maximum at its closest approach to Jupiter. Jupiter sped up the spacecraft substantially, and the VOYAGER 2 slowed down Jupiter's orbital speed a very tiny amount. As VOYAGER 2 climbed out of Jupiter's gravitational field, the Jupiter relative velocity outbound was the same as its velocity inbound. However, VOYAGER 2 left the Jovian environs carrying an increase in angular momentum stolen from Jupiter. The momentum gained by the spacecraft equals that lost by the planet. Examples include Venus-Earth-Earth Gravity Assists (VEEGA) used by the U.S. spacecraft GALILEO, or Venus-Venus-Earth-Gravity-Assists (VVEGA) used by the U.S. spacecraft CASSIN. Also known as slingshot orbits
V2S > V1S
V2j < V1j
V2SMs - V1jMs = V1jMplanet - V2jMplanet
momentum gained by spacecraft = momentum losed by the planet.
V1S = Velocity of the spacecraft before encountering the Planet Jupiter's Gravity and momentum. [km/s]
V2S = Velocity of spacecraft after encountering the Plant Jupiter's gravity and momentum. The spacecraft is speeding away from Jupiter, and has gained momentum at Jupiters expense. [km/s]
V1j = Velocity of the Planet Jupiter before the spacecraft encounters Jupiter's gravity. [km/s]
V2j = Velocity of the Planet Jupiter after the spacecraft has encounterd Jupiter's gravity and the spacecraft has gained velocity by steeling some of Jupiters momentum.[km/s]
Ms = mass of spacecraft
Mplanet = mass of planet

guidance.....Determining the location and direction of travel of a launch vehicle, spacecraft, or satellite and make whatever corrections are necessary to keep to the desired path and reach the destination. 3 basic types of guidance system are used; inertial, using electromagnetic radiation, and command.
- Beam Rider; follows the path of a beam of electromagnetic radiation generated externally.
- Celestial Navigation; follows a path using celestial bodies as reference points.
- Command; follows commands sent to the guidance system by external sources.
- Command Radio Guidance; Command guidance using the radio part of the electromagnetic spectrum
- Fin stabilization; aerodynamic surfaces that stabilize the flight path. Only work in an atmosphere.
- Homing; detects electromagnetic energy emitted from the object, (transmitted or reflected), and follows the emitted energy to the target.
- Inertial; The guidance system measures the forces acting on the launch vehicle, spacecraft or satellite, and controls the direction to ensure it is on the correct trajectory.
- Infrared; Senses heat from a object or destination and follows the heat source.
- Optical; Involves horizon tracking or terrain feature recognition to determine path. See also Celestial Navigation.
- Radar Beam; Follows the reflected radar signal from an object or location to that target or location.
- Radar control; Radar signals sent from the launch vehicle, spacecraft or satellite, reflect of the object or location, and are followed by the vehicle.
- Radio Navigation; Path of the vehicle is determined by the time measure of the radio signal.
- Rotational inertia; Rotating the launch vehicle, spacecraft or satellite to provide dynamic stability.
- Terrestrial Reference; The path of the launch vehicle, spacecraft or satellite is determined by a terrain over which it travels using electromagnetic radiation, and/or gravity.
