The KEA V41NA4 GNSS receiver is an FPGA based receiver platform ideally suited as a working receiver or as a reference design for teaching, research or further product development. It is a small form-factor receiver designed for pin compatibility with other OEM GPS receivers.
The KEA receiver features an Altera Cyclone™ 5E FPGA and with embedded memory and phase locked loop circuitry. The receiver firmware runs on the Altera NIOS 32 bit RISC soft core processor. The GNSS base-band logic is also contained in the Cyclone™ 5E FPGA. The receiver architecture is designed to allow multiple NIOS soft core processors to operate in the same FPGA if required. There is additional unused logic capacity in the FPGA for expansion and development.
The RF down-converter uses a custom wide band ASIC to convert the GNSS signal to a low 4MHz IF for sampling. It allows access to both GPS L1 and Galileo E1 signals.
The receiver is delivered as a working GNSS receiver and can be customised to any end user requirements on request.
