Design, document, code, and test application layer software to control a satellite ground station. This project begins with a survey of existing satellite ground station remote control software, from custom VPNs to SatNOGs control...
This project implements design approaches discussed by Tom Clark K3IO and Kerry Banke N6IZW, where an injected local signal is used to stabilize a 10 GHz downlink signal received by a dish antenna. Higher...
Applied Ion Systems (https://appliedionsystems.com/) is an ongoing open source research and development effort into low-cost propulsion systems for CubeSats. This project addresses immediate software programming needs in simulation, visualization, and control of Applied Ion...
Theseus Cores (https://www.theseus-cores.com/) is an open source collection of powerful field programmable gate array (FPGA) designs for digital communications. The polyphase channelizer is a central component of Open Research Institute’s receiver designs. This project...
From Wikipedia, “Single instruction, multiple data (SIMD) is a class of parallel computers in Flynn’s taxonomy.[clarification needed] It describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously. Such machines exploit data level parallelism, but not concurrency: there are simultaneous (parallel) computations, but only a single process (instruction) at a given moment. SIMD is particularly applicable to common tasks such as adjusting the contrast in a digital image or adjusting the volume of digital audio. Most modern CPU designs include SIMD instructions to improve the performance of multimedia use.”
From Wikipedia, “In computing, a fixed-point number representation is a real data type for a number that has a fixed number of digits after (and sometimes also before) the radix point (after the decimal point ‘.’ in English decimal notation). Fixed-point number representation can be compared to the more complicated (and more computationally demanding) floating-point number representation.”
“If a building looks better under construction than it does when finished, then it’s a failure.” – Douglas Coupland
The research question is how a genetic algorithm would perform compared to the linear programming (LP) and satisfiability (SAT) backtracking algorithms in low density parity check decoders. This would support the Phase 4 Transponder...
Tired of crappy User Interfaces in amateur radio? This project takes that challenge on!
