Development of FPGA-Based Ingest System with Multi-Output Interface for Receiving Low Resolution Remote Sensing Satellite Data

Mastery of Field-Programmable Gate Arrays (FPGA) technology is very important as an ingest card for receiving remote sensing satellite data. FPGA has many advantages, one of which is that it can support multiple output interfaces so that it can receive remote sensing satellite signals from the demodulator simultaneously with the data rate according to the incoming satellite signal. In this development, Cypress EZ-USB FX2 and FTDI UART have been implemented as output interfaces from the FPGA to the Ingest host. The Cypress EZ- USB FX2 interface has a speed of up to 480 Mbps while the FTDI UART interface has a maximum speed of 3 Mbps and 12 Mbps. This ingest design was developed using Very High-Speed Integrated Circuit Hardware Description Language (VHDL) and realized on the Altera Cyclone IV EP4CE6 FPGA Development board using Intel Quartus Prime Lite 22. The implementation results show that the design can operate receiving NOAA-18/19 and MetOp-B/C satellite signals from the demodulator and storing raw files satellite data to Ingest host. With the same satellite signal input, both Cypress EZ-USB FX2 and FTDI UART output interfaces can generate the same raw data file.
