Using Satellites in the Classroom: A Guide for Science Educators.
The function, design, and ground statics ceguirements of the AMSAT-OSCAR ncn-ccmmercial space satellite system are described, and various experiments designed for direct student participation in space communications are provided in this text primarily written for the science educator. Six chapters include:) (1) an introduction to general satellite crtit problems and sclutione, (2) a number of tracking methods_ for ccmputing the positicns of 1 satellites, (3) onboard systems common to most satellites, (4) ai complete descripticn of each of the satellites currently in orbit or planned for the near future, (5) specifics fcr ground stations, and (6) four complete student satellite experiments, 15 detailed prcject outlines, and 19 suggestions for topics and activities. AppendiCes include listings of equipment manufactirers and publishers, as well as a glossary of terms. .(Author/RAO) #31g4g###########*31g#714########*###*######****************7144**714*71444714### * Reproductions supplied by EDRS are the ,best that car be made * * from the original document. * *********************************************************************** U.S. DEPARTMENT OF HEALTH.

Intersatellite communication using the AMSAT-OSCAR 6 and AMSAT-OSCAR 7 radio amateur satellites
Ground-satellite-satellite-ground intersatellite communication using the AMSAT-OSCAR 6 and AMSAT-OSCAR 7 radio amateur satellites is described. The closest approach period (centered around the end of January, 1975) may represent the first use of two satellites interlinked directly to support communications between two earth stations.
Concept design of solar cell satellite dish
Solar panels are devices that consist of solar cells that convert light into electricity. They are called solar on the Sun or “sol” because the Sun is the strongest light source that can be utilized. Solar panels are often called photovoltaic cells, photovoltaic can be interpreted as “light-electricity”. Solar cells or PV cells depend on the photovoltaic effect to absorb the Sun’s energy and cause currents to flow between two opposing charged layers. The purpose of this study is to analyze the satellite dish using solar panels, so this tool is a signal search tool that uses solar energy to run to carry out its functions. As we know that many places or areas that are still often experiencing power outages so that it can hamper and interfere with community activities. Therefore, this research wants to facilitate the public, especially the current generation who need electricity every day so that when there is a power outage, the satellite dish will utilize solar energy as its main source. This research uses a satellite dish as an intermediary to produce electrical energy with the help of solar energy and is collected into a high-voltage battery in the form of electricity, so that it becomes a source of electricity.
