ARLS005 ARISSat-1 On the Air for Gagarin Anniversary<\/span><\/p>\n

To celebrate the 50th anniversary of the first <\/span>human spaceflight<\/span> by<\/span>
cosmonaut Yuri Gagarin, the ARISSat-1 satellite aboard the<\/span>
International Space Station will be on the air using the station’s<\/span>
external antenna. Transmissions will begin on Monday, April 11, at<\/span>
14:30 UTC and continue until 10:30 UTC on April 13.<\/span><\/p>\n

To preserve the satellite’s battery, transmissions will cycle on and<\/span>
off. ARISSat-1 will transmit for 40 to 60 seconds, and then remain<\/span>
silent for 2 minutes.<\/span><\/p>\n

The FM transmissions on 145.950 MHz will alternate between a voice<\/span>
ID, telemetry values, SSTV images and audio greetings in 15<\/span>
different languages. One of the transmissions will contain audio of<\/span>
a conversation between Gagarin and ground controllers that was<\/span>
recorded during the historic flight.<\/span><\/p>\n

A CW beacon will be heard on 145.919 MHz cycling between the<\/span>
ARISSat-1 call sign, telemetry and call signs of individuals<\/span>
involved in the ARISS program.<\/span><\/p>\n

BPSK-1000 telemetry transmissions will also take place on 145.920<\/span>
MHz SSB using the new 1kBPSK protocol developed by Phil Karn, KA9Q.<\/span><\/p>\n

AMSAT will issue commemorative certificates to listeners who receive<\/span>
the ARISSat-1 transmissions. Reports can be e-mailed to<\/span>
Gagarin@arissat1.org<\/span><\/a> or <\/span>yuri@arrisat1.org<\/span><\/a>. Include your name, call<\/span>
sign, a description of what you heard and the <\/span>UTC time<\/span> you heard it.<\/span>
Recording the battery voltage telemetry values and the UTC time you<\/span>
received them will be especially helpful.<\/span><\/p>\n

You can determine when the International Space Station will be<\/span>
passing overhead by using the AMSAT-NA online pass prediction tool<\/span>
at, <\/span>http:\/\/www.amsat.org\/amsat-new\/tools\/predict\/<\/span><\/a>.<\/span>
