The Space Flight Laboratory (SFL) at the University of Toronto Institute
for Aerospace Studies (UTIAS) would like to announce the delivery of
Nanosatellite Launch Service 6 (NLS-6) cluster payload to Satish Dhawan
Space Centre in Sriharikota (SDSC-SHAR), Andhra Pradesh, India, for
launch on board PSLV-C15. PSLV-C15 will be launching from the First
Launch Pad at SDSC-SHAR into 637 km sun-synchronous orbit with 10:30
Local-Time of Descending Node. NLS-6 shares this launch with Cartosat-2B
primary, Alsat-2A co-primary, and STUDSAT auxiliary payload.
NLS-6 is the 6th launch by SFL. The NLS-6 cluster comprises of two
nanosatellite: AISSat-1 and TIsat-1.
NLS-6 launch updates are being posted to
AISSat-1 is built by SFL for the Norwegian Defence Research
Establishment (FFI). It is intended to demonstrate a new maritime AIS
receiver that has been developed by FFI. The AIS receiver will be used
to monitor ship traffic in Norwegian waters. The design of AISSat-1 is
based on SFL Generic Nanosatellite Bus (GNB).
The spacecraft has a main structure measuring 20 cm by 20 cm by 20 cm
and it is stabilized in three-axes using reaction wheels. It has a fixed
46 cm long VHF payload monopole antenna for the AIS receiver and four
UHF uplink monopole antennas for the command receiver. The downlink in
the S-Band. AISSat-1 has an overall dimension of 80 cm by 45 cm by 37 cm
and an overall mass of 6.5 kg. AISSat-1 will be secured to the launch
vehicle using the XPOD GNB separation system.
AISSat-1 is not an amateur satellite and, as such, has coordinated
appropriate frequencies. Its ground segment is located at Svalbard and
its control centre is at FFI, near Oslo, Norway.

TIsat-1 is a 1 kg CubeSat of 10 cm by 10 cm by 10 cm and is built by
students and staff at University of Applied Sciences of Southern
Switzerland (SUPSI). The primary mission objective is to involve
students in systems engineering, development and test with a very
challenging project and to provide students and staff at SUPSI with
space mission knowledge. TIsat-1 will monitor the durability of material
probes exposed to space environment, will test a micro electromechanical
device and will validate the redundant, fault tolerant hardware and
firmware design of the bus.
Two monopole antennas (VHF and UHF) will be deployed after separation.
Housekeeping and payload data will be communicated to the ground as
orbital data profiles. TIsat-1 will be secured to the launch vehicle
using the XPOD Single separation system.
TIsat-1 communicates over amateur radio frequencies, as coordinated
through the IARU, and they have been working with radio amateurs in
Switzerland during the spacecraft's development. They have a Morse Code
and data beacons. More information can be found at
Future Launches by SFL
SFL has signed its 7th launch contract with ANTRIX for NLS-7 in late
2010/early 2011. NLS-7 will launch the twin-satellite CanX-4 and CanX-5
formation flying mission.
SFL will be signing its 8th launch contract for NLS-8 momentarily, for
the launch of two astronomy nanosatellites: BRITE-Austria (CanX-3A) and
UniBRITE (CanX-3B). NLS-8 will also launch one partner spacecraft.
In addition, SFL is under discussion for NLS-9, NLS-10, and NLS-11
launches in 2011/2012 time frame, and would like to extend an invitation
to spacecraft developers world-wide to join our launches.
