-------------------- Sedtime program Q&A -------------------- Q] Downloaded the SEDTIME.zip---How and when is this used ? Don't understand that one at all ! A] 'Sedtime.exe' is a program to calculate the 'RESET TIME' in SEDSAT(SO-33). The program to receive the telemetry from SEDSAT is available as 'Sgs20.exe' on http://uah.seds.org/projects/sedsat/ http://www.ne.jp/asahi/hamradio/je9pel/sgs20.zip Downlink 437.910 MHz, 9600 baud FSK, mode KISS The output format of this 'Sgs20.exe' is the followings. ............................................................................................... | Mon, Day, Year, Hour, Min, Sec, Main Voltage, ......, UpDays, UpHours, UpMinutes, UpSeconds | | 2, 2, 2000, 8, 37, 12, 21142, ......, 001, 00, 35: 00 | .......................................................... .................................... It mean the received current date is 08:37:12UTC, 2 Feb 2000, and 'Uptime' is 1_day and 0_hour 35_min. 0_secs. Then you use 'Sedtime.exe' to calculate the 'RESET TIME'. ................................................... Input data: Day Hour Minu. Sec. Current Time 2 8 37 12 Up Time 1 0 35 0 Press OK_button, then Output data is calculated automatically below: Day Hour Minu. Sec. Reset Time: 1 8 2 12 ................................................... Then We will know 'RESET TIME' is 08:02:12UTC, 1 Feb 2000. And we will not have to worry about the 24 hour conversion factors in this way.
