ISISPACE S-Band High Data Rate Transmitter sets a new standard for CubeSat communication, offering unmatched performance with up to 4.3 Mbps of reliable downlink data transfer. Fully CCSDS-compliant, it ensures seamless compatibility with ground stations and off-the-shelf demodulators, eliminating the need for data pre-processing. All channel coding is performed inside the transmitter. With in-flight configurable parameters, this transmitter provides ultimate flexibility to optimise throughput during satellite overpasses, making it a top choice for high-performance missions.
