Are More Satellite Outages Ahead?
Norwood - June 4, 1998 - The sudden failure of PanAmSat's Galaxy IV has made everyone aware of just how vulnerable satellites--and the delivery of a growing range of telecom services--are. Though the Galaxy IV's problem was attributed to an internal system error, industry observers say such occurrences may increase in frequency due to a little-known phenomenon: space weather, a topic covered extensively in the May '98 issue of Telecommunications magazine. In the article, written and researched by Jared Bazzy, engineers from the industry share their expertise and candid opinions regarding the potentially disastrous effects of solar surges, atomic particles, and electromagnetic fields. Donald Margolies, a NASA engineer, said, ``There have been a number of satellites damaged or destroyed. If the (satellite operators) had known, it's possible they might have taken action and avoided it.'' Margolies manages the Advanced Composition Explorer, an unmanned satellite that orbits the Earth to determine the composition of space weather and transmits data to Earth in an attempt to provide accurate and updated forecasts for satellite ground operations. Other sources for the article include Carl Jeffcoat, vice president of engineering at COMSAT World Systems, and Bruce Burlton, director of satellite operations for Telsat Canada.

Satellite Launch To Boost DTH In India
Calcutta, India (SPX) Dec 28, 2005The successful launch Thursday of India's heaviest satellite from spaceport of Kourou in French Guyana may have boosted the country's space research efforts to yet another level, but it has also lifted the spirits of at least three Direct-To-Home televisions broadcasters, one of which has been waiting for years to launch its services in India. |
