USSOCOM Checkpoint Bravo
short description
To prove the feasibility of using payloads on 3U form factor cube-sat.
Bio
Introduce yourself or your team
I am a computer engineer with data communications background from CISCO.
What makes you an ideal candidate for this Challenge?
I have a science and engineering background with experience in data communication using CISCO routers.
Solution
Describe your solution.
The feasibility of using a cube-sat with GPS location signal receivers communications payload from ground, air or sea targets (persons or objects) is proposed. Also we use encoded transmitted signals which are decoded after the signals are received by the cube-sat. I think encrypting tracking signals is needed so that even if such signals were intercepted, it will bear no meaning to the interceptor.
What is the size of your proposed solution?
My proposal uses the 3U form factor.
Does your solution help Special Operations Forces missions? How?
My cube-sat GPS location tracker will help the SOF operators to tag, track and locate target persons or objects and make further strategic movements or decisions based on that information.
Where known, identify platform accommodation requirements for power.
Platform accommodation requirements for the cube-sat GPS tracker will need at least 45 watts of power for the communications payload, GPS sensor, smartphone motherboard, and for the visible light high resolution camera.
Where known, identify platform accommodation requirements for thermal control.
Platform accommodation requirement for thermal control by containing most electronics like smartphone, communications payload inside a pressurized bag with multi-layered textile, just like an astronaut spacesuit. The cube-sat is set on a permanent spin so as to expose the surface equally during the time it is exposed to the sun and the spacesuit bag will protect when there is no sun exposure.
Where known, identify platform accommodation requirements for data transfer rate.
Platform accommodation requirement for data transfer rate less than 64 kbits/ sec. of data to be transferred to the ground if operating in a real-time data transfer mode.
Where known, identify platform accommodation requirements for data transfer volume (per orbit).
Platform accommodation requirement for data transfer volume (per orbit) is less than 10 MB of data per orbit to be transferred to the ground if operating in a store-and-forward mode.
Where known, identify platform accommodation requirements for bus stability and attitude control.
Platform accommodation requirements for bus stability is by using standards based satellite buses and attitude control is by using reaction wheels if need to correct the cube-sat attitude but will recommend a permanent spinning attitude with the visible-light camera pointed to the earth at all times to be able to take ground photos.
Can you identify any additional platform accommodation requirements for your solution?
None for now.
Can your concept can be implemented with current state-of-the-art flight-qualified components, or will it require additional development? Please describe.
My concept can be implemented with current state-of-the-art flight-qualified components or COTS electronics so as to lower the cost of the cube-sat and are able to make the prototype on a shorter time frame of at least within 12 to 24 months.
Intellectual Property: Do you acknowledge that this is only the Concept Phase of the competition, and all ideas are to remain the property and ownership of USSOCOM for future discretionary use, licensing, or inclusion in future challenges?
Yes
