ValBal’s current electrical system consists of two compact, low-cost, 4 layer printed circuit boards with a custom avionics platform and a prototype digital radio communication link. The avionics consist of a multitude of sensors, a GPS, a two-way satellite communications system, motor drivers, power regulation, an embedded micro-controller, and much, much more! The digital radio system consists of a 433 MHz GFSK modulated, Reed-Solomon error corrected link that has been proven to reach ranges of 200 km at data-rates significantly greater than that of the Iridium constellation at 1/5th of the power consumption and 1/20th the cost. There are a multitude of ways to join the electrical engineering aspect of ValBal, so if any of this stuff interests you, join! Contact {{slack-user|ariatedjarati}} for more information.

With ValBal CS, you will learn how to design and build robust, reliable, and flight critical embedded systems code. Since we cannot simply patch the firmware when it is flying, and if something goes wrong we could literally crash, we have to model our system in a way that accounts for complex states, edge cases, and emergent properties. From smart subsystem rebooting to bidirectional comms with parameter tuning, and from a multitude of flight modes to heavily optimized processor and memory behavior, ValBal is the perfect place to hone your skills building something that not only works, but works to industry standards.

*Physics -- As a physics major, there are plenty of opportunities for you to work on ValBal. It is an insanely complex system; the flight dynamics are not yet completely understood and require simulating atmospheric and thermal effects. Good models are critical to create a good controller, another key component to ValBal that limits our possible endurance. At the same time, you can help with the design of the payload itself, considering how to optimize it for the harsh environment and coming up with good designs.
