Re: NCube-2



Good news on the possibility of N-cube.
 
Apx AOS for the next north to south passes for the USA are:
 
02.34    Low elevation pass over Atlantic. OK from East  coast
04.12    East coast
05.50    Good coverage all USA
07.28    Mid to West coast

Hi  All,

We have received a report from NORAD that they have recently  detected an 
additional object in an orbit which is very close to SSETI  Express.

It is possible that this could be NCube-2 which should have  been deployed 
from Express just after launch on October 27th.

It  would be really good to see if signals from NCube-2 can be detected on  
437.305MHz +/- Doppler.

NORAD will be cataloging this new object as  28897 and an element set should 
be forthcoming shortly - in the meantime  the existing SSETI Express 
TLEs/Keps will be accurate  enough.


Here is some prelaunch data to help recognition of the  signal!


Downlink: 437,305MHz
Bitrate: 9600b/s
Modulation  technique: GMSK

The message:
"DE=LA1CUB=NCUBE2=FF=LA1CUB===" is morsed using a 2400Hz  
tone, 26 words per minute" where FF is a hex number [00=3,0V -  FF=4,5V]
If battery voltage is above 3,8V,  every 2 minutes
If battery voltage is below  3,8, every 5 minutes
In the end of the message an unnumbered AX.25 packet  is attached containing 
the string:

DE=LA1CUB=NCUBE2=NORWEGIAN  CUBESAT - WWW.NCUBE.NO
