Starling satellites “will automatically adjust their measurement techniques in order to take advantage of their relative positions,” Cannon said. With GPS receivers, Starling satellites will monitor ionospheric density and move around to further explore regions of particularly high or low density. The final Starling experiment, Distributed Spacecraft Autonomy, relies on artificial intelligence to make plans based on ionospheric observations. “The ground planning software is a reference to see how well the autonomous satellites are performing in this kind of test scenario,” said Praveen Kurian, 元Harris general manager for space superiority. While the Starling satellites conduct autonomous operations in orbit, 元Harris Technologies will be running a variation of its flight dynamics planning software on the ground. ![]() “ROMEO is integrating our Autopilot and Navigator flight software products to demonstrate autonomous station keeping and reconfiguration of the Starling swarm.” “Coordinated autonomous maneuvering will be required for future constellations and swarms where communications delays and bandwidth limitations make ground-based control impractical,” said Austin Probe, chief technology officer for Emergent Space Technologies. The third demo, Reconfiguration and Orbit Maintenance Experiments Onboard (ROMEO), will test whether Starling satellites can maneuver autonomously to achieve their objectives. “By exchanging and processing these cameras measurements, we are able to determine the orbits of all the spacecraft.” “For the first time, we will give a swarm the capability to autonomously navigate in space without GPS, using only cameras embedded in these four cubesats pointing at one another,” said Simone D’Amico, who leads Stanford University’s Space Rendezvous Laboratory. Starling satellites will rely on star trackers to move into various formations and prevent collisions. Next up is the Starlink Formation-Flying Optical Experiment, known as StarFOX. “That is what we are trying to solve here with NASA.” “If one of the satellites goes out of range or fails, how do you make sure that network still meets a certain level of reliability and throughput,” asked Shey Sabripour, founder and CEO of CesiumAstro, which is providing Starling’s software-defined radios with S-band intersatellite links. Starling mission managers will test whether the six-unit cubesats can establish and maintain a dynamic communications network. EXPERIMENT LINEUPįirst up is the Mobile Ad-hoc Network experiment. ![]() NASA intends to find out during the six-month Starling mission with a series of experiments. It remains to be seen whether communications, navigation and autonomy technologies are advanced enough for swarm operations. “Turbulence is inherently a multiscale process and those multiple scale sizes must be sampled simultaneously to understand how energy is conveyed.”ĭespite the promise, swarms in general and the Starling mission specifically present challenges. “HelioSwarm’s nine spacecraft form an observatory to provide the first ever simultaneous, multiscale observations in the solar wind needed to understand space plasma turbulence,” Harlan Spence, HelioSwarm principal investigator and director of the University of New Hampshire Institute for the Study of Earth, Oceans and Space, said by email. HelioSwarm mission managers will communicate with the hub satellite built by Northrop Grumman, which will coordinate operations of eight smaller spacecraft built by Blue Canyon Technologies. HelioSwarm, for example, is a $250 million mission NASA plans to launch in 2028 to study solar wind turbulence with nine satellites.
