KySat-2 (K2) is a 1U CubeSat to fulfill the education and public outreach mission of the original KySat-1 CubeSat that was lost during a launch vehicle failure of ELaNa I and accompanying NASA GLORY mission.
With the same motivation as KySat-1 K2 will include upgraded components and best practices that have been developed within the institutions in charge of designing, building, and operating the spacecraft in orbit. These institutions are:
• Kentucky Space LLC: Mission Management
• Morehead State University (MSU): Communications, power systems
• University of Kentucky (UK): On board computer, imaging payload
Once in orbit the spacecraft will transmit on the amateur UHF band and beacon using the AX.25 protocol to portable ground station already developed by MSU for outreach in K-12 grades. Those using the mobile ground stations will only be able to listen for beacons unless fully licensed. It is proposed to use a UHF 12kHz wide downlink.
The expected telemetry on the beacon expects to include basic spacecraft health (batt voltages, solar cell temperatures) which will be tied in with lesson plans being developed jointly by Kentucky Space. Larger data sets will be transmitted on the UHF band including measurements of attitude control with the included 3 axis accelerometers and gyroscopes that are included on the spacecraft.
The main payload of the spacecraft will be what is being called by the development team as a “stellar gyro”. This imaging system will serve two purposes:
1. The imager will take successive images when looking at star field to run algorithms to determine the spacecrafts relative attitude, role rate, and perhaps other measurements that can be back out from the relative movement of stars taken by the spacecraft.
2. Capable of taking images of the earth to sublimit the education and public outreach part of the mission. These images will be downloaded at MSU & UK ground stations and posted on the mission website for users and educations.
All student operators and engineering team members are required to obtain an individual amateur radio operators license.
The ELaNa launch is currently scheduled for Summer 2013.
