Hsinchu, Taiwan – January 16, 2026 – YTTEK, a leading provider of wireless communication solutions, has been awarded a crucial contract by the Taiwan Space Agency (TASA) to develop the core communications payload for Taiwan’s ambitious Beyond 5G (B5G) Low Earth Orbit (LEO) satellite initiative. Since the contract award in June 2025, the project has progressed steadily and has now entered the engineering verification phase.

The contract, officially titled “Pathfinder Communication Payload Baseband Module Prototype Development,” positions YTTEK at the forefront of the nation’s push for space communication autonomy. YTTEK will leverage its core expertise in Software-Defined Radio (SDR) technology to design, implement, and verify the fundamental components of the first domestically developed LEO satellite payload.

SDR at the core: Building the next-generation communications payload

TASA’s B5G satellite initiative includes two experimental LEO spacecraft. The first payload (1A) was contracted to U.S.-based CesiumAstro, while the 1B satellite—designed to showcase Taiwan’s indigenous aerospace capabilities—will be developed domestically.

TASA will lead the 1B payload development in collaboration with top Taiwanese companies, including YTTEK, and research institutions.

“We are honored to join TASA’s national space team,” said Jiangson Chen, CEO of YTTEK. “YTTEK will apply its deep experience in SDR system design to deliver a high-integration, high-value wireless communications payload that advances Taiwan’s autonomy in LEO satellite technology.”

Strengthening Taiwan’s space manufacturing and B5G competitiveness

The B5G experimental satellite program serves two missions: Technology validation and building Taiwan’s domestic space supply chain. The Taiwan-developed 1B satellite is scheduled to launch in 2030. YTTEK’s participation highlights the country’s commitment to establishing a resilient and fully local communications payload ecosystem.

As the Pathfinder phase of the 1B communications payload program formally enters the engineering verification stage, YTTEK’s participation underscores Taiwan’s commitment to building a resilient, fully indigenous communications payload ecosystem and strengthening its competitiveness in the global B5G landscape.

Proven reliability: Validated by TASA missions

YTTEK specializes in SDR-based wireless communication-modules for satellites and defense-grade Unmanned Aerial Vehicles (UAVs). The company’s HyperSDR satellite ground station modem has already demonstrated space-grade reliability by successfully receiving and decoding signals from TASA’s Formosat-5 and NASA’s Landsat-8 and Landsat-9 satellites.

Building on these proven capabilities, YTTEK’s participation in the Pathfinder payload program further extends its experience from ground-based systems to spaceborne communications payloads.

Hsinchu, Taiwan – September 11, 2025 – YTTEK, a leading innovator in software-defined radio (SDR) technology, today announced a major breakthrough in Taiwan’s defense capabilities. The company will showcase the nation’s first indigenous anti-jamming UAV communication transceiver at the Taipei Aerospace & Defense Technology Exhibition (TADTE) 2025, a significant milestone for Taiwan’s sovereign defense communications.

Unmatched resilience for contested environments

At the core of YTTEK’s exhibition is the SDRone UAV transceiver, a system engineered for critical missions in hostile electronic warfare environments. The SDRone features a wide frequency switching range from 300 MHz to 6 GHz (covering L- and S-bands) and a high-speed frequency hopping rate of 2,000 hops per second. This powerful combination delivers advanced anti-jamming and anti-detection performance, ensuring resilient command-and-control links, secure data transmission, and enhanced UAV survivability.

“Modern battlefields demand not only endurance and mobility but also secure, resilient communications,” said Jiangson Chen, CEO of YTTEK. “We are proud to be the first in Taiwan to introduce this technology. The SDRone is designed to provide robust anti-jamming and anti-detection capabilities to ensure mission success under the most challenging conditions.”

Enhanced operational flexibility with C4ISR integration

Designed with C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance) principles in mind, the SDRone supports edge computing integration and features a compact, SWaP-C (Size, Weight, and Power-Cost) optimized architecture. Its point-to-multipoint (P2MP) capability allows a single operator to control multiple UAVs simultaneously, significantly boosting mission efficiency and operational flexibility.

Proven expertise in satellite and defense communications

In addition to its UAV solutions, YTTEK will highlight its proven expertise in satellite communications. As a long-term partner of the Taiwan Space Agency (TASA), the company’s HyperSDR high-speed satellite transceiver has successfully received and decoded signals from TASA’s Formosat-5 mission and NASA’s Landsat-8 and Landsat-9 satellites. This track record underscores the proven reliability of YTTEK’s wireless solutions and highlights its strong position in the global defense and space markets.

Building on these success, YTTEK is now actively leveraging its expertise to support UAV system integrators and government stakeholders in the defense sector.
