NCube-2



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

In the header of the AX.25: Callsign: NCUBE  Destination: EARTH

The satellite will transmit at a power of 1,5W at full battery charge

Reception reports will be welcome email to ncube@rocketrange.no   and to 
missioncontrol@sseti.org

Keep those fingers crossed
