YTTEK debuts its all-in-one SDR satellite modem with X/Ku-band support

Innovation breakthrough: All-in-one platform for X and Ku-band

Traditional ground stations have long been burdened by cumbersome external up/down converters, leading to high deployment costs and system fragility. YTTEK’s HyperSDR ground station modem addresses this by integrating RF front-end and modem functions into a unified, high-performance architecture.

This design allows a single device to directly interface with both X and Ku frequency bands—a significant advancement that reduces hardware footprints and simplifies the path for rapid terminal deployment. In an era where agility is paramount, YTTEK’s integrated SDR solution offers a streamlined path for operators by consolidating modulation, signal analysis, PCIe high-speed data transfer, and massive data storage into a single, unified platform.

Proven performance: Validated by TASA’s FORMOSAT-5 mission

YTTEK’s entry into the international market is backed by rigorous operational validation. Working in deep collaboration with the Taiwan Space Agency (TASA), YTTEK’s proprietary ground transceiver equipment has already demonstrated its reliability in high-stakes environments.

The system successfully received and decoded high-resolution imagery from Taiwan’s FORMOSAT-5 and has further proven its reliability by decoding signals from NASA’s Landsat-8 and Landsat-9 satellites. These milestones position YTTEK as a key player in the Asian aerospace sector with a field-proven track record in satellite data reception.

Targeting 2027 launch for communication payload

Building on its ground-proven systems, YTTEK will showcase a high-throughput satellite communication payload designed for CubeSats and Low Earth Orbit (LEO) satellites. This payload features a Software-Defined Radio (SDR) architecture supporting dual X/Ku bands and a 720 Mbps downlink data rate, and is targeted for launch in 2027 to secure critical flight heritage.

Strategic expansion in Asia-Pacific

At SatelliteAsia 2026, YTTEK will exhibit alongside its regional distributor, Linkwen Electronics. This partnership leverages YTTEK’s technological innovation and Linkwen’s extensive system integration expertise to provide localized service and support across the Asia-Pacific region.

YTTEK’s end-to-end satellite communications architecture: space, ground, and mobility.

Ground segment: National space agency-validated, mission-proven performance

YTTEK has built its satellite communications expertise through long-term collaboration with the Taiwan Space Agency (TASA). Its satellite ground station modem has been mission-proven, successfully receiving and decoding signals from TASA’s Formosat-5 and NASA’s Landsat-8 and Landsat-9 satellites. These accomplishments position YTTEK among the few Asian firms with verified, national-level satellite communications credentials.

Space segment: Targeting 2027 launch for communication payload

Building on its ground-proven systems, YTTEK will showcase a high-throughput, flexible satellite communication payload designed for CubeSats and Low Earth Orbit (LEO) satellites. The payload features a Software-Defined Radio (SDR) architecture that supports multiple protocols and overcomes the limitations of traditional fixed hardware. It is targeted for launch in 2027 to secure flight heritage.

Automotive Segment: Redefining Satellite Connectivity for Smart Mobility

Expanding into smart mobility, YTTEK has partnered with Tier-1 supplier AUO Mobility Solutions Corporation to co-develop a next-generation automotive satellite User Terminal (UT). The solution combines AUO’s roof-integrated transparent glass antenna with YTTEK’s satellite communication system for user terminals. Featuring a millisecond-response Antenna Control Unit (ACU) built for seamless modem integration, YTTEK’s system ensures precise satellite tracking and uninterrupted connectivity, even at high speeds across complex terrains.

From integration to complete systems

“As global LEO deployments accelerate, competition is shifting from individual components to system-level integration,” said Jiangson Chen, CEO of YTTEK. “Our goal is to build a complete satellite communications solution—from ground to satellite to vehicle.”
At Satellite 2026, YTTEK aims to deepen collaboration with global aerospace leaders and system integrators, leveraging its end-to-end integration capabilities to strengthen Taiwan’s strategic role in the global LEO satellite ecosystem.

About YTTEK Technology

YTTEK, a leader in Software-Defined Radio (SDR), delivers cutting-edge wireless communication solutions for satellite communications, defense UAV and academic applications. We are dedicated to offering proven, reliable, and integrated communication solutions, helping customers accelerate product development and ensure exceptional performance.

The SOTM solution enables vehicles to connect to LEO satellite networks through translucent phased-array antennas, supporting real-time Vehicle-to-Everything (V2X) control, Over-the-Air (OTA) software updates, High-Definition (HD) mapping, and in-vehicle digital services. Unlike traditional terrestrial networks, satellite connectivity extends coverage beyond ground infrastructure, providing more resilient and reliable connections across wide geographic areas.

The project combines two core innovations. AUO’s translucent SatGlass Antenna enables satellite antennas to be virtually invisible by integrating them directly into the vehicle sunroof. Meanwhile, YTTEK’s high-performance Antenna Control Unit (ACU) and satellite modem deliver millisecond-level tracking for stable connectivity in motion. Together, these technologies ensure seamless satellite access without compromising vehicle aesthetics.

By combining YTTEK’s mission-validated satellite communications technology—demonstrated through successful signal reception and decoding from TASA’s Formosat-5 and NASA’s Landsat-8 and Landsat-9 satellites—with AUO’s innovative glass-based substrates, the collaboration addresses long-standing trade-offs between high-performance connectivity and automotive design, accelerating the realization of satellite-connected smart mobility.

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.
