The frequency allocation and approval process for satellite radio transceivers can take over 36 months, and is often not completed prior to procurement and integration of crystal-based transponders (transceivers). Spectrum management now relies more on off-channel assignments within the Space-Ground Link System (SGLS) band and is converting satellite services to Unified S-Band. Satellite manufacturers cannot anticipate a frequency assignment conforming to availability of off-the-shelf crystals. Hence, it will be useful to have programmable transceivers that can lock to an assigned frequency within the SGLS band or the Unified S-Band a month before launch or even while on-orbit. This will allow space programs to continue space vehicle integration and testing in parallel with the frequency approval process. To address this, IAI has been awarded a contract to design a Reconfigurable Digital Transceiver (RDT) for Space Applications. The proposed design will be initially prototyped on a custom Multi-Channel Digital Synthesizer and Processor (MCDSP) platform that has been designed and field-tested by IAI for digital transceiver applications. IAI’s innovation lies in integrating fixed crystal oscillator based transceivers with wideband digital frequency synthesis capability to cover SGLS and the Unified-S band. This approach proposes the use of a single 2.4 GHz oscillator and also of augmenting wideband direct digital synthesizers to cover the entire SGLS/ Unified S-band spectrum. The proposed RDT design will use space grade components and conservative design strategies, in order to be space-qualifiable in the future.
