Scintillation-Hardened GPS

A Space Communications and Navigation (SCaN) flight experiment will demonstrate Next Generation Navigation Techniques and Advance SDR/STRS Communications Technology to TRL-7. Scintillation-hardening techniques will be applied to an open-source waveform ported to the SCaN platform. This will result in improved GPS navigation during geomagnetic storms. The ported waveform will be STRS-compliant and open source. It will provide a validation of the STRS architecture and software defined radio technology for space applications. While operational, the waveform will autonomously detect scintillation and automatically switch into a data collection mode for relaying the GPS samples to the SCaN avionics subsystem for later transmission to White Sands. The open-source, STRS-compliant waveform software and GB of GPS scintillation data will be enduring products of the flight demonstration. The STRS infrastructure will be expanded with the STRS tool kit produced during this project. The STRS tool kit will be similar to the OSSIE tool kit for the SCA, providing automatic code generation of STRS wrappers and interfaces. An eclipse-based framework will provide drag-and-drop of components for developing STRS-compliant software.
