As I mentioned back in April, the Space Flight Laboratory (SFL) at the
University of Toronto Institute for Aerospace Studies (UTIAS) has
arranged for the launch of two satellites as part of the Nanosatellite
Launch Service 6 (NLS-6) cluster payload on the PSLV-C15 from the Indian
Space Research Organization. Two satellites are part of NLS-6: AISSat-1
The launch countdown for PSLV-C15 has begun, and it is on track to
launch on July 12, 2010 at 03:52:00 UTC. The window is -0/+10 min, i.e.
from 03:52:00 to 04:02:00 UTC.
AISSat-1 is built by SFL for the Norwegian Defence Research
Establishment (FFI), and it is intended to demonstrate a new maritime
AIS receiver that has been developed by FFI.
TIsat-1 is a 1 kg CubeSat built by students and staff at University of
Applied Sciences of Southern Switzerland (SUPSI). TIsat-1 uses amateur
radio frequencies and has CW and data beacons. Details and frequencies
can be found at
More detail on the spacecraft can be found below from my original post.
We will have an IRC discussion channel during launch and the early
Port: 6667 (default)
I will send out the predicted TLEs later today.
