HSINCHU, Aug. 26, 2026 /PRNewswire/ — YTTEK Technology announced today that its 
HyperSDR Satellite Ground Station Modem successfully received and decoded high-speed
X-band downlink data from the Taiwan Space Agency’s (TASA) FORMOSAT-8A (FS-8A, "
Chi Po-lin") satellite during an orbital pass on April 27, 2026. The system compensated
for rapidly changing Doppler shifts and reconstructed 0.7-meter-resolution optical
imagery covering Alibag, India.

FORMOSAT-8A is the first satellite of Taiwan’s FORMOSAT-8 optical Earth observation
constellation, the country’s first domestically developed optical remote sensing
constellation. Its 0.7-meter resolution—nearly six times finer than FORMOSAT-5—generates
large volumes of data that must be processed within limited LEO communication windows.
HyperSDR supports a 600 Mbps downlink data rate and up to 2.25 Gbps of processing
throughput per channel. To date, the system has decoded more than 2 TB of FS-8A 
downlink data, with data collection continuing across subsequent orbital passes.

_"Higher-resolution imagery means larger data volumes and places greater demands
on ground equipment within limited communication windows," said Dr. RJ Chen, Director
of R&D at YTTEK. "As satellite constellations expand, flexible and high-performance
ground systems will become increasingly important for managing frequent satellite
passes and high-volume data reception."_

Built on an FPGA-powered Software-Defined Radio (SDR) architecture, HyperSDR can
be software-reconfigured to support different frequency bands, satellite missions,
and communication protocols, with frequency coverage from 10 MHz to 15 GHz. This
flexibility enables the ground system to support multi-satellite operations and 
provides a foundation for Non-Terrestrial Network (NTN) applications.

This achievement builds on YTTEK’s previous satellite ground reception experience,
including FORMOSAT-5 and NASA’s Landsat-8 and Landsat-9 missions, extending the 
company’s mission experience to Taiwan’s FORMOSAT-8 constellation and further demonstrating
Taiwan’s domestic capabilities in supporting high-throughput satellite missions.
