KickSat Sprites set for launch

*Zac Manchester KD2BHC* has released this update on *KickSat* which will
carry 104 tiny Sprite satellites into a 325×315 km 51.5 degree inclination
orbit. The launch of the SpaceX Falcon 9 CRS 3 mission is planned for March
30.

We’re almost there! The launch is on for Sunday, March 30 from Kennedy
Space Center in Florida.
You can watch the launch live on NASA TV, which will also be streaming
online on Ustream <http://www.ustream.tv/nasaedge> (Zac may be interviewed
prior to launch).

Here’s a rough sequence of events*:*

- Falcon 9 launch (0:00)
- Falcon 9 upper stage separation (+0:03)
- Dragon capsule separation +0:10)
- KickSat deployment from Falcon 9 upper stage (+0:16)
- KickSat powers on and begins transmitting telemetry (+1:06)
- Sprite deployment (+16 days and 16 minutes after launch)

The Sprites will be deployed by a timer exactly 16 days after KickSat is
deployed from the launch vehicle. The timing was arranged with NASA to
avoid interference with ISS operations.

Once KickSat turns on its radio, you should be able to pick it up with very
basic Ham radio gear. It will be transmitting telemetry packets in AX.25
format on 437.505 MHz with 1200 baud AFSK modulation. I’ll post KickSat’s
orbital elements here and on the project wiki, which will also have more
information on setting up a receiving station. As always, don’t hesitate to
contact me if you have any questions.

Thanks for your support!

Each Sprite has a microcontroller, radio, and solar cells and is capable of
carrying single-chip sensors, such as thermometers, magnetometers,
gyroscopes, and accelerometers.

All the Sprites satellites operate on a single frequency of 437.240 MHz and
use Code Division Multiple Access (CDMA). The transmitter runs 10 mW output
of Minimum Shift Keying (MSK) modulated binary data with each data bit
modulated as a 511 bit Pseudo-Random Number (PRN) sequence. The ITU
emission designator is 50K0G1D. The KickSat CubeSat has downlinks on
437.505 MHz and 2401-2436.2 MHz.
