The beacon is turned off during eclipse to avoid stress of the batteries. This message is repeated each 15s and is encoded with 17 WPM. The radio used as beacon has been developped completely in SUPSI with the help of local HAMs. The following table allows to translate the last character of the message into the relative temperature expressed in Celsius degrees. Character F B K R H N T E I S A D M U 5 L Temperature -10 -5 0 +5 +10 +15 +20 +25 +30 +35 +40 +45 +50 +55 +60 +65 We invite to keep note of the received messages and temperatures. A Web application to upload these information will be soon available. http://www.spacelab.dti.supsi.ch/tiSat1MS.php TIsat-1 CW Beacon Decoder Register, phpBB SSL - SUPSI Space Laboratory Download, TIsat-1 CW Beacon Decoder

StudSat Mission Mode Subject: Frequency Clarification From: mamatha rm Date: Mon, 19 Jul 2010 10:04:07 +0530 Hi, Yes we are operating in the same frequency that is 437.861MHz for Beacon. We have received the Beacon in the same frequency. Thanking you, Mamatha (Team STUDSAT) StudSat reference: Satellite Completed the beacon mode of communication and has entered the mission mode, where in it will transmit encrypted data at 437.505 MHz and will not send the beacon. http://www.teamstudsat.com/live.html TIsat-1 reference: 11:39 and 13:14UTC, 29 Dec 2011, 145.980MHz FM beacon mp3 --> vvv hb9de tisat1 k 01:05-01:17UTC, 30 Dec 2011, Ele 55 N-E-S, 437.305MHz CW beacon 2011-12-30 01:15:00 7929 HI HI HI TISAT B 2011-12-30 01:15:07 7929 HI HI HI TISAT B 2011-12-30 01:15:14 7929 HI HI HI TISAT B 2011-12-30 01:15:21 7929 HI HI HI TISAT K 2011-12-30 01:15:28 7929 HI HI HI TISAT K
