The TubeSat is a lightweight, inexpensive personal satellite designed by Interorbital Systems. Its design enables a degree of modification so that users can personalize the functionality of their satellite before it is launched into low earth orbit (LEO) onboard Interorbital’s Neptune Modular Series rockets. This one is ours.
We have completed the assembly and functional testing of the core satellite system which includes several circuit boards:
- Microcontroller PCB – Arduino micro, several PICs to perform encoding and decoding of data stream to onboard radio transceiver
- Transceiver PCB – The radio and amplifier mounted on this board allow 1200bps Narrow Band FM AFSK communication with the earth ground station
- Power Management PCB – Components on this board control the charging of onboard battery by solar cells and voltage regulation
- Antenna PCB – Here we have a 70cm band dipole antenna for radio transmission and reception
Our next step is to design our “Experiment/Application Space” or payload. What experiments will we carry out in space? What types of transmissions will be sent? Photos? Music?
