Phase Four, one of the leaders in advanced radio-frequency thrusters for small satellite propulsion, has announced the successful flight heritage of its next-generation Maxwell propulsion system. This marks a major step in deploying state-of-the-art propulsion technology for small satellites.

The advances in the Maxwell propulsion system underscore Phase Four's commitment to excellence, innovation, and customer-focused solutions towards providing reliable, cost-effective propulsion systems tailored towards proliferated Low Earth Orbit (LEO) small satellite missions. A continued differentiator for Phase Four is its focus on providing a full suite of products and services for in-space propulsion.

It is noteworthy that Phase Four's propellant fill operations were completed with its engineering team using in-house developed Ground Support Equipment (GSE) for this critical component of launch preparation for the Maxwell propulsion system. Phase Four takes pride in seamlessly integrating propellant fill operations and on-site support, ensuring mission flexibility while adhering to industry-standard safety protocols such as AFSPCMAN 91-710 and AIAA/ANSI S-080A. Additionally, Phase Four performs a comprehensive telemetry check during on-site visits, covering all system channels, and ensuring optimal propulsion subsystem condition before launch. All Maxwell propulsion units are delivered with an initial propellant load for optional end-to-end testing and hot fires with each spacecraft, ensuring mission readiness.

Phase Four's 24-hour commissioning support services ensure optimal deployment of the Maxwell propulsion system. As a mission partner seeking to continuously improve customer success, Phase Four has already delivered Over-the-Air (OTA) software updates for the system's on-orbit performance, ensuring adaptability and mission optimization post-deployment. Another innovation worth noting is the Built-in Self-Test (BIST) feature of the latest Maxwell system, enabling thruster function validation anytime, anywhere, enhancing system reliability.

Phase Four, a "one-stop-shop" propulsion provider, allows customers to focus on satellite applications and mission objectives. The newest Maxwell system's flight heritage is a significant milestone in Phase Four's quest to redefine small satellite propulsion, with its customer-centric approach, dedication to innovation, and unwavering commitment to safety.
