ARLS004 Ten New Satellites in Orbit

Ten satellites reached orbit April 28 aboard an Indian PSLV-C9
rocket launched from the Satish Dhawan Space Center. The primary
payloads were India's CARTOSAT-2A and IMS-1 satellites. In addition
to the NLS-5 and RUBIN-8 satellites, the rocket carried six CubeSat
research satellites, all of which communicate using Amateur Radio
frequencies. All spacecraft deployed normally and appear to be
functional at this time.

The SEEDS satellite is designed and built by students at Japan's
Nihon University. When fully operational, SEEDS will download
telemetry in Morse code and 1200-baud FM AFSK packet radio at
437.485 MHz. The satellite also has Slow-Scan TV (SSTV) capability.
Several stations have reported receiving SEEDS CW telemetry and the
team would appreciate receiving more reports from amateurs at their
ground station Web page.

AAUSAT-II is the creation of a student team at Aalborg University in
Denmark. It will downlink scientific telemetry at 437.425 MHz using
1200 or 9600-baud packet.

Can-X2 is a product of students at the University of Toronto
Institute for Aerospace Studies, Space Flight Laboratory
(UTIAS/SFL). Can-X2 will downlink telemetry at 437.478 MHz using 4
kbps GFSK, but the downlink will be active only when the satellite
is within range of the Toronto ground station.

Compass-One was designed and built by students at Aachen University
of Applied Sciences in Germany. The satellite features a Morse code
telemetry beacon at 437.275 MHz. Compass-1 will also provide a
packet radio data downlink, which will include image data, at
437.405 MHz.

Cute 1.7 + APDII is a satellite created by students at the Tokyo
Institute of Technology. This satellite will not only provide
telemetry, it will also offer a 9600-baud packet store-and-forward
message relay with an uplink at 1267.6 MHz and a downlink at 437.475

Delfi-C3 was designed and built by students at Delft University of
Technology in the Netherlands. It includes an SSB/CW linear
transponder. The satellite will be in telemetry-only mode for the
first three months of the mission, after which it will be switched
to transponder mode. Delfi-C3 downlinks 1200-baud packet telemetry
at 145.870 MHz. The linear transponder, when activated, will have an
uplink passband from 435.530 to 435.570 MHz and a corresponding
downlink passband from 145.880 to 145.920 MHz.
