Preparations are underway for a new, small spacecraft technology demonstration that will test cost-efficient swarm capabilities - the ability for multiple spacecraft to communicate and perform coordinated actions. The PY4 mission's four CubeSats are slated to launch Monday March 4, 2:05 p.m. PST to low Earth orbit aboard SpaceX's Transporter-10 mission from Vandenberg Space Force Base in California.
Led by Carnegie Mellon University in Pittsburgh and funded by NASA's Small Spacecraft Technology program, PY4 seeks to demonstrate spacecraft-to-spacecraft ranging, in-orbit navigation, and coordinated simultaneous multi-point radiation measurements at low size, weight, power, and cost.
It uses a unique avionics platform called PyCubed that integrates power, computing, communications, attitude determination, and orbit control functionalities into a single board system. The PyCubed system is also open-source, programmable entirely in the Python programming language and uses affordable commercial off-the-shelf components.
Once in orbit at over 325 miles above Earth, the spacecraft will periodically measure their relative distances. These range measurements provide information about the spacecrafts' positions relative to each other, and when combined with other sensor data, can be used to determine the configuration of the swarm. Advancing these capabilities could decrease the workload for operators on the ground while enabling multi-spacecraft missions at an accessible price point.
