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.
