Please answer the following question: Information:  - Galaxy IV was a model HS - 601 satellite built by Hughes Space and Communications Company ( HSC ) . The satellite , which carried a payload of both C band and Ku band transponders , was launched on June 24 , 1993 and operated by PanAmSat Corporation . Control of Galaxy IV was lost on May 19 , 1998 when the satellite 's primary control processor failed . The backup control processor had suffered a previously undetected anomaly , and PanAmSat was not able to regain control of the spacecraft . Galaxy IV was declared a loss on May 20 , 1998 . Failure of the primary control processor was attributed to tin whisker growth , a phenomenon in which tendrils grow from solder , causing an electrical short circuit . Engineers believe that a hole developed in the conformal wax coating over the solder , allowing whiskers to develop . The satellite manufacturer , Hughes , has replaced pure tin plating with nickel to alleviate the problem in newer designs , adding 45 to 90 kg per payload . The loss of this satellite was very disruptive to telecommunications in the United States . Pagers were affected greatly ; service was not restored for days . Wire news services , like Reuters , were also affected . The TV network CBS had to use alternate means of transmitting its programs , as did NPR . At the time of failure , Galaxy IV was in geostationary orbit at 99 ° W. This orbital slot was briefly occupied by Galaxy 4R , and is now occupied by the Galaxy VI satellite . Galaxy IV remains in space .  - An Internet service provider (ISP) is an organization that provides services for accessing and using the Internet. Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned.  - Univision is an American Spanish language broadcast television network that is owned by Univision Communications. The network's programming is aimed at Latino Americans and includes telenovelas and other drama series, sports, sitcoms, reality and variety series, news programming, and imported Spanish-language feature films.  - In telecommunication, a transponder is one of two types of devices. In air navigation or radio frequency identification, a flight transponder is an automated transceiver in an aircraft that emits a coded identifying signal in response to an interrogating received signal. In a communications satellite, a satellite transponder receives signals over a range of uplink frequencies usually from a satellite ground station, amplifies them, and re-transmits them on a different set of downlink frequencies to receivers on Earth, often without changing the content of the received signal or signals.  - The former PanAmSat Corporation founded in 1984 by Reynold (Rene) Anselmo, was a satellite service provider headquartered in Greenwich, Connecticut. It operated a fleet of communications satellites used by the entertainment industry, news agencies, internet service providers, government agencies, and telecommunication companies. Anselmo got the idea for PanAmSat from Norm Leventhal, a communications lawyer in Washington, D.C., to whom he had turned to for advice regarding difficulties he was encountering in getting reasonably priced satellite transmission for his Spanish International Network (SIN), the current-day Univision. Anselmo financed the entire project himself and Leventhal's law firm, hiring Martin Rothblatt for special satellite technical advice, filed for approval from the Federal Communications Commission and lining up an initial satellite from RCA Astro-Electronics and a heavily discounted launch from Arianespace.  - A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. There are over 2,000 communications satellites in Earths orbit, used by both private and government organizations.  - Greenwich is a town in Fairfield County, Connecticut, United States. As of the 2010 census, the town had a total population of 61,171. The largest town on Connecticut's Gold Coast, it is home to many hedge funds and other financial service companies. Greenwich is the southernmost and westernmost municipality in Connecticut as well as the six-state region of New England. It is 38+ minutes by train (express) from Grand Central Terminal in Manhattan. CNN/Money and "Money" magazine ranked Greenwich first on its list of the "100 Best Places to Live in the United States" in 2005. The town is named after Greenwich, a borough of London in the United Kingdom.    'galaxy iv' is related to which object entity through the relation of 'instance of'?  Choices: - census  - channel  - coast  - communication  - communications satellite  - corporation  - england  - entertainment  - fleet  - hedge  - industry  - internet  - language  - law  - law firm  - lawyer  - may  - money  - municipality  - norm  - orbit  - organization  - population  - profit  - programming  - radio  - series  - service  - six  - television network  - town  - variety
