NCube-2
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
