The US Navy’s Office of Naval Research (ONR) is looking to develop a new class of subminiature radio frequency (RF) signal processor payload for the sea service’s growing arsenal of unmanned platforms, according to a 13 May industry solicitation.
The new RF processing payload system being developed under the ONR programme, dubbed the Neptune Payload Prototype Project, will be designed to “support multiple RF missions with a limited set of hardware, a wideband transceiver capability with self-contained software-defined or reconfigurable hardware-accelerated processing as required”, the Request for Solutions (RFS) notice by the Strategic & Spectrum Missions Advanced Resilient Trusted Systems (S2MARTS) other transactional authority (OTA), stated.
“Candidate component technologies that are available for integration to satisfy ONR’s payload requirement include currently available integrated wideband RF transceiver chipsets, Field-Programmable Gate Array (FPGA), RF Application-Specific Integrated Circuit (RF ASIC), Radio Frequency System-on-Chip (RFSoC), and high-performance microcontrollers,” the solicitation added.
Navy programme officials have set a five-year window for development work on the Neptune payload prototype, at an estimated cost of USD3.7 million over the duration of the effort, according to the RFS. The ONR engineers are open to integration of commercial off-the-shelf (COTS)-based software-defined radio technologies into prototype offerings, given those COTS technologies meet “current high-technology readiness levels (TRL)” as defined by the programme officials, the solicitation stated.
