EchoStar I
EchoStar I is a communications satellite operated by EchoStar. Launched in 1995 it was operated in geostationary orbit at a longitude of 77 degrees west for 12 or 15 years. The company has approved the transfer of the 77 degree west orbital position to QuetzSat as of September 22, 2010.

Satellite
The launch of EchoStar made use of a Long March rocket flying from Xichang Satellite Launch Center in Sichuan province of the People's Republic of China. The launch took place at 11:50 UTC on December 28, 1995, with the spacecraft entering a geosynchronous transfer orbit. The spacecraft carried 16 Ku band transponders to enable direct broadcast communications and television channels through 0.5 meter dishes on the ground in the American continents.[1][2]

gollark: Create a new section "Bees" %bees.Create a rule "Bee utilization part 1" (%bees-1) in %bees:> The deployment status of bees is considered part of the Game State. No bee action (except for bee deployment) may be taken unless bees are currently deployed. Bee actions include deployment of bees, which makes bees become deployed, cessation of bees, which makes bees not be deployed, and use of bees against a player. The player bees are to be used against must be indicated in the Bee Poll authorizing this action. Use of bees against players causes their Points quantity to be reduced by 1, unless it is already 0, in which case there is no effect.Create a rule "Bee Poll" (%bee-poll) in %polls:> A Bee Poll is required to authorize bees to perform actions, as described in %bees. The default allowed reactions for a Bee Poll are 👍 (representing a vote for) and 👎 (representing a vote against). Bee Polls may be closed if they have existed for 12 hours or more, rather than the usual 24. If a Bee Poll is passed, the action it describes is taken. Players are permitted to use multiple reactions on a Bee Poll. A Bee Poll must clearly indicate that it is a Bee Poll.Due to the passage of proposal #207, bees are to be considered "deployed" initially.
gollark: Because funlolz.
gollark: I'm describing it.
gollark: No.
