BA1. The Ground Sphere CubeSat Ground Station is being built specifically to receive ""tweets from space" which will be broadcast by the SkyCube CubeSat. A side effect of having such a low cost and easy to use ground station is the educational opportunities in areas including satellite orbits, radio technology, telecommunications, and programming.
BA2. The Ground Sphere CubeSat Ground Station is for SkyCube backers, students, teachers, scouting troupes, space enthusiasts, and anyone who wants to directly experience satellite communications and participate in the SkyCube mission.
BA3. Ground station operators will use the ground station and its accompanying software to:
BA4. The designs will be open so that anyone, without necessarily a technical education in amateur radio or satellite operations, would be able to build and operate a Ground Sphere CubeSate Ground Station. Note, the first kits will be built by SkyCube KickStarter backers.
TA1a. The project needs to:
TA1b. In the future, the project (or related projects) may need to:
TA2. To maintain compatibility with other projects, the system should:
PA1. As an open source hardware kit, the long term objective is to promote and sell as many ground station kits to as large of an audience (schools, scouting troupes, makerspaces, space enthusiasts, etc) as possible. However, the narrow focus on supporting SkyCube operations with the Ground Sphere may limit the number of kits which will be sold for this specific ground station, especially since the SkyCube is going to be on orbit for a very limited period of time. The sales lifetime of this specific kit (and in turn the number of kits we will want to sell) will depend on how many other satellites there are to observe in the same frequency range as the SkyCube. Note, there are approximately 2700 backers of the SkyCube KickStarter, of which Southern Stars is committed to delivering ground stations to between 20 and 30 backers. This gives a minimum number of ground stations to be built of 30 +/- 5, which would cover the minimum backers and a handful for Mach 30's use.
The timing of the project may also limit the scale of the initial run Mach 30 can produce. This decision will be revisited later in the development process (after the second prototype) to allow the development team to address the manufacturing logistics.
PA2. The materials cost should be kept under $100 to limit the retail cost of the kit. There are currently three prototypes planned. The project budget should cover all three prototypes plus overage. To that end, the threshold project budget (max) is $500 and the objective is $400.
PA3. The timeline for this project is dictated by the SkyCube launch and deployment timeline. SkyCube is currently scheduled to be launched in December 2013, with deployment from the ISS in Q1 or Q2 of 2014. Southern Stars has stated they would be comfortable with a February 2014 delivery date for the kits. This gives a kit completion date of early January 2014 to give enough time to spool up manufacturing and shipping for the February due date.
