PY4 is the third CubeSat mission using the open source PyCubed avionics framework. PY4 is also the third collaboration between Carnegie Mellon University’s Robotic Exploration Laboratory and NASA’s Ames Research Center in California’s Silicon Valley.

The PY4 mission aims to enable autonomous swarms of small spacecraft by both reducing the manufacturing cost and integration effort required for individual spacecraft, and by advancing guidance, navigation, and control algorithms that increase autonomy and reduce or eliminate the need for expensive sensor, actuator, and propulsion hardware.

2024年3月5日 · The PY4 mission intends to demonstrate a low-cost approach to multiple-satellite missions. Advancing autonomy and proving that relatively small and inexpensive satellites can succeed could reduce mission and operational costs dramatically for subsequent missions.

2023年8月1日 · PY4 is a low-cost, rapid-turn-around, four-satellite technology demonstration based on the open-source PyCubed avionics framework. PyCubed is an open-source, radiation-tested CubeSat avionics platform that integrates power, computing, communication, and attitude determination and control functionality into a single low-cost module programmable ...

2024年3月4日 · PY4 could dramatically reduce the cost of small spacecraft swarming capabilities and make demonstrating technologies like the autonomous navigation system tested via Starling more widely accessible by offering a flight-ready hardware and software platform.

Python四星 （PY4）是卡内基梅隆大学（Carnegie Mellon University）研发的3U立方星。 用于测试具有成本效益的集群能力——即多艘航天器进行通信并执行协同动作的能力 [1]。

2024年3月6日 · The goal of PY4 is to demonstrate low size, weight, power, and cost (SWaP-C) spacecraft-to-spacecraft ranging, in-orbit relative navigation, and coordinated simultaneous multi-point radiation measurements.

NASA has deployed a mission that will test a cost-efficient spacecraft swarm technology. The mission, called PY4, sent four CubeSats to low Earth orbit aboard SpaceX’s Transporter-10 …

The PY4 mission aims to enable autonomous swarms of small spacecraft by both reducing the manufacturing cost and integration effort required for individual spacecraft, and by advancing guidance, navigation, and control algorithms that increase autonomy and reduce or eliminate the need for expensive sensor, actuator, and propulsion hardware.

2024年3月6日 · PY4 builds on Manchester's previous satellite swarm mission, V-R3x. That mission, launched in January 2021 also in partnership with the Small Spacecraft Technology program, placed three small...
