- 2012 CoDR Mission Statements RocketSat 8 shall integrate and
validate the Roll Out De-Orbiting Device (RODEO) developed by
Composite Technology Development (CTD). This shall provide a means
to de-orbit future small satellites. RocketSat 8 shall validate an
attitude determination system for future RockSat missions
- Slide 3
- 2012 CoDR Theory and Background 23 small satellites
(10kg-500kg) launched every year by the United States Growth of
small satellites in space exponentially increases the likelihood of
collisions The rise in the number of satellites in orbit has led to
an increasing need for a cost effective and lightweight means to
de- orbit small satellites. The RocketSat VII attitude
determination system was successful, but the accuracy of the system
couldnt be verified since there was no known solution for the
attitude of the rocket.

Parent Requirement S1.1Shall deploy in a time sufficient for the
needs of the missionS1 S2.1Shall capture an image of RODEO while it
is in the field of view of the camera S2 S2.2Shall set a image
frame rate and quality that confirms RODEO deployment S2 S2.3Shall
store the image dataS2 S3.1Shall detach from rocket at the
determined timeS3 S3.2Shall detach from rocket without damaging
equipmentS3 S3.3Shall generate acceleration upon detachmentS3
S4.1Shall measure deceleration of the RTSS4 S4.2Shall transmit
deceleration data from RTS to the rocketS4

(continued) Parent Requirement S6.1Shall have sufficient power to
perform all required operationsS6 S7.1Shall use attitude sensors
that are within five degrees of accuracy S7 S7.2Shall incorporate
an attitude determination algorithm that is accurate to within ten
degrees of accuracy S7 S8.1Shall employ attitude sensors that can
determine the attitude on all three axes S8
- Slide 8
- 2012 CoDR Minimum Success Criteria Mission success depends on
the image capture of the deployed RODEO device. Secondary mission
success is determined by the validation of the RocketSat8 attitude
determination system

- 2012 CoDR Mission overview: Expected Results We expect: the
RODEO system to be fully extended while attached to the rocket to
capture an image of the extended RODEO system the RTS to detatch
from the rocket canister to measure deceleration from the RTS to
transmit the deceleration data from the RTS We expect to
characterize the rockets attitude and verify it with a known
solution 10

- 2012 CoDR The structure thus far will be composed of two
plates. The bottom plate will include the RTS containing the
deployable given to us by Composite Technology Development, as well
as the ejection system. The electronics boards and the ADS(Attitude
Determination System) will all be utilized on the top plate with
the cameras. 13

- 2012 CoDR The payload shall conform to the requirements set
forth in the 2011 RockSat-X User Guide The system shall
successfully deploy the hardware manufactured by Composite
Technology Development. The structure will interface with RockSat-X
through provided mounting surfaces. 16
- Slide 17
- 2012 CoDR All electronic interfaces will be held in place
throughout the duration of the flight with the exception of the
deployable. The structure will withstand the forces of launch and
protect the scientific and electrical systems. The structure will
thermally protect the electronics for as long as reasonable data
can be collected. The system shall successfully take at least one
photo of the deployable as it leaves the canister, and house the
cameras securely during launch. 17
- Slide 18
- 2012 CoDR The ejection system shall be durable enough to
survive the forces of launch. The structure shall allow exposure to
an open air environment while still protecting electronics and
instruments from harm. 18
