PARUS is a family of CubeSats developed and used by the Taiwan Space Agency.
The family is named after the Chestnut-bellied tit (Sittiparus castaneoventris) which is endemic to Taiwan. [1]
PARUS-T1A was launched in 2024 but failed to achieve orbit due to rocket failure. PARUS-T1 achieved orbit following a January 2025 launch [2] as part of SpaceX's Transporter-12 mission. [3] PARUS-T1 orbits at 515-kilometers, within low Earth orbit. [4] It is a 3U class cubesat and carries experimental telecommunications and Automatic identification system payloads. [1]
PARUS-T2 was launched to orbit in June 2025. It has a primary communications payload. It has a domestic Automatic Packet Reporting System (APRS) and a domestic altitude determination and control system (ADCS). The ADCS is made by Tensor Tech. PARUS-T2 has a planned mission life of 12 months and orbits at 621 kilometers. [5]
PARUS-6U1 is scheduled for launch in October 2025 as part of SpaceX's Transporter-15 mission. [5]
