CHIPS: CubeSat HTP Innovation Propulsion System
A high-performance, green propulsion system designed specifically for CubeSats.
A high-performance, green propulsion system designed specifically for CubeSats.
CHIPS is a cutting-edge project developed under ESA Contract No. 4000132061/20/NL/RA. Developed by the University of Pisa, CHIPS offers a reliable, low-cost, and eco-friendly alternative to toxic hydrazine-based thrusters. Designed with a compact form factor, it provides the maneuverability required for modern small satellite missions.
CHIPS utilizes 98% concentration High Test Peroxide (HTP) as a monopropellant. Unlike traditional toxic fuels, HTP is safer to handle and environmentally friendly, classifying CHIPS as a "green" propulsion solution. The system uses a specialized Platinum on α-Alumina pellet catalyst to achieve efficient decomposition.
Compact Design: The entire system fits within a 2U volume envelope and weighs less than 1.2 kg (dry mass), maximizing payload space for operators.
Cost-Effective: By utilizing Commercial Off-The-Shelf (COTS) components where possible, the overall system price is kept ≤ 50 k€.
Innovative Tank: To overcome standard limitations, the project designed a custom cuboidal tank capable of storing up to 0.45 liters of propellant within a 1U envelope.
Clean Assembly: All components are passivated and assembled in a clean room environment to prevent contamination and ensure safety.
