Air Force awards IAI a new contract to develop a Reconfigurable Digital Transceiver for Space Applications

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.
