Decoding table for TIsat-1 beacon messages: 437.305MHz

13.07.2010

During the early days of TIsat-1 mission, during the day the beacon continuously sends the message “HI HI HI TISAT” followed by a Morse character indicating the temperature of the transmitter. 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 completely developped at SUPSI with the help of local HAMs. The encoding of the temperature is reported in the next table.

Please report the received values, quality of signal, time and location. A Web application to help conversion and upload these information is available.
