Iris Deep-Space Transponder

Ability to change rate of communication, encryption, and the frequency of electromagnetic waves to send data over is the basic need of every deep space spacecraft. Fitting these capabilities into a handheld box for next generation cube satellites is a creative challenge that will enable more agile and proof-of-concept science!

A Space Mission is an emergent success due to numerous dedicated engineers assembling and testing it.
Which parts did I work on?
1. Led a team of engineers to deliver radios for cube satellite missions (EM-1). Was responsible for verifying functionality of various components such as digital signal processing board, transmitter, receiver, and power supply board.
2. Programmed, tested, and integrated FPGA modules for various signal processing and digital communication modules (Turbo, Viterbi, Reed-Solomon).
3. Integration and testing of radio that flew to Mars as an initial proof of concept for deep space cube satellites (MarCO-A and MarCO-B).
