The mission, led by Pennsylvania State University, places an x ray observatory on a CubeSat platform to capture transient x ray events and study bursts from the collapse of early stars into black holes, probing conditions in the early universe using the sensitivity of Teledynes detector technology.
At the heart of the BlackCAT payload, a 2 by 2 mosaic of Speedster HyViSI focal plane arrays forms the primary imager, enabling the spacecraft to monitor some of the most energetic phenomena in the cosmos. The Speedster design uses a Si PIN hybrid CMOS architecture that is optimized for space based x ray detection, providing high efficiency for soft x ray photons while maintaining the robustness required for long duration missions in orbit.
The Si PIN array delivers high quantum efficiency in the soft x ray band, allowing the instrument to register faint signals from distant and short lived sources that are central to BlackCATs science goals. The hybrid structure couples this absorber layer to a CMOS readout, combining the spectral performance needed for astronomy with the flexibility and radiation tolerance associated with modern integrated electronics.
Teledyne highlights that the CMOS functionality in Speedster HyViSI underpins several key performance advantages for the CubeSat instrument. Event driven fast readout allows the detector to capture and process x ray hits as they occur, improving temporal resolution for rapid transient events while reducing unnecessary data volume when the field is quiet.
Low power operation is another core attribute of the Speedster architecture, a critical factor for CubeSat platforms that must operate within tight electrical and thermal budgets. The detector electronics are designed to support efficient power use without compromising readout speed or signal quality, helping the BlackCAT spacecraft maintain stable operations during extended observation campaigns.
Radiation hard performance is also central to the Speedster HyViSI implementation, ensuring that the focal plane arrays can operate reliably in the space environment over the planned mission lifetime. By combining radiation tolerant CMOS circuitry with a robust absorber design, the detector aims to sustain sensitivity and calibration as it encounters charged particles and other space weather effects in low Earth orbit.
X ray detection is described by Teledyne as a natural extension of the HyViSI technology family, which has already been applied in other imaging domains. Dr Yibin Bai, Director of FPA Development, stated that with its adaptable CMOS features and advanced absorber design, the Speedster HyViSI establishes itself as a high performance alternative to other sensors for x ray astronomy in space, positioning the platform for future missions and instruments.
Through its Space Imaging business, Teledyne manufactures advanced electronics, imaging systems and sensor solutions for space applications across the growing global space economy. The group has a long heritage of supplying space qualified imaging sensors, focal plane arrays and camera systems to major agencies including NASA, ESA, JAXA and KARI, contributing to more than 250 space projects spanning scientific, Earth observation and commercial missions.
Teledyne Space Imaging develops CCD, CMOS and infrared detectors with a range of optical filters, packaging options and proximity electronics to meet diverse performance requirements. The company delivers imagers for institutional science programs as well as commercial space operators, aligning each focal plane design with specific spectral, resolution and environmental targets defined by mission teams.
Teledyne Space Imaging forms part of Teledyne Technologies, whose operations extend across digital imaging products and software, instrumentation, aerospace and defense electronics and engineered systems. Headquartered primarily in the United States, Canada, the United Kingdom and Western and Northern Europe, Teledyne supports a broad customer base in both government and commercial markets that rely on high performance sensing and imaging capabilities.
The BlackCAT deployment continues Teledynes practice of placing its imaging technologies at the center of space instruments that observe high energy astrophysical events. By pairing the Speedster HyViSI focal plane arrays with an x ray optical system in a compact CubeSat form factor, the mission seeks to demonstrate that small spacecraft can deliver scientifically valuable data on some of the most distant and dynamic processes in the universe, potentially shaping the design of future distributed constellations of x ray observatories.
