A stratospheric balloon project.
The ultimate goal of this project is to build semi-autonomous stratospheric balloon that can do some basic scientific measurements, take pictures and communicate with ground station. The main difference from other similar projects is that we want to figure out a way for the balloon to _stay in stratosphere long-term_, not just come up and right back down.
To successfully complete this project, various sub-goals have to be met:
designing the balloon in reasonably scalable way and assembling one
defining the payload equipment (board, comms, metering interfaces)
designing and manufacturing the payload enclosure (heat and pressure issues)
solving a reasonable power supply (photovoltaic cells, rechargeable batteries and clever power management)
do some research, propose and test a communication protocol (remember we cannot be sure where it will be blown to)
And then the final goal will be:
The project is currently in the planning stage. Everything has to be done from scratch.
