Wideband PNT OORDWG

ABSTRACT: Innoflight proposes to develop a novel Wideband PNT On-Orbit Reprogrammable Digital Waveform Generator (ORDWG). This ORDWG is considered wideband because it will have the ability to generate PNT signals in the existing GPS, GLONASS, Galileo, and Beidou (Compass) bands, plus nearly anything in between. The ORDWG will be able to be reprogrammed on-orbit and will support cryptography external to the waveform generator, but for expandability"s sake, it will also be able to support cryptography within the reprogrammable boundary. The Wideband PNT ORDWG has several unique features that bring together the latest software-defined radio technology and high performance radiation-hardened electronics. BENEFIT: PNT is a technology that will never disappear. For the foreseeable future, all PNT technologies are based off of GPS technology with only minor modifications, at most. This implies that the ORDWG will be at the core of PNT satellites for a very long time. Additionally, due to the power of the architecture, assuming that all performance metrics are equivalent or better, the ORDWG technology will supplant all traditional waveform generators. Additional applications include more general-purpose signal generation for spacecraft including being employed as a functional block within an RF exciter. This dual-use will allow the hardware platform to be used in nearly any communications application in need of reprogrammable and/or mission configurable features.
