Running Constellations: A Flight Dynamics Viewpoint – SpaceNews
In an period where by technological innovation is advancing at an remarkable amount, satellite functions in Minimal Earth Orbit (LEO) continue on to working experience rapid modify like never ever right before. In the initial fifty percent of 2021, more than 1,000 mainly LEO satellites have launched. Federal Communications Fee (FCC) filings and current market research signifies that thousands of LEO satellites could be on orbit by 2030. This exponential growth is dominated by a number of significant constellations, with a handful of operators flying additional than 1,000 satellite constellations. In addition, the world market place is evolving as many businesses operate towards lesser constellations of five to 50 satellites, with unique desires at that scale. It is in this context that a.i. methods sat down with Andrew Werner, Director of House Solutions at the corporation.
What purpose does a.i. solutions participate in in the modernization of satellite operations?
a.i. solutions is an engineering solutions company specializing in satellite flight dynamics (also identified as orbital mechanics or astrodynamics) — identifying exactly where your satellite has been, figuring out where it will be looking at the several forces performing on it, and scheduling maneuvers to fulfill the satellite’s targets — all although protecting proper orientation, conference conversation and sensor protection demands, and averting particles and other satellites.
In 2021, we celebrate 25 decades of delivering flight dynamics knowledge and application to civil, armed service, professional, intercontinental, and educational prospects. Across mission setting up, start, early mission, on-orbit, and disposal [phases], a.i. solutions has enabled the achievements of hundreds of satellites, such as the International House Station (ISS), GPS, Landsat, and the Geostationary Operational Environmental Satellite (GOES). We also build FreeFlyer®, the most impressive, flexible, and operationally verified and validated flight dynamics COTS [Commercial off-the-shelf] computer software on the industry. FreeFlyer allows engineers to customize room mission design, evaluation, and operations functions to fulfill their distinct requirements. In addition to our dependable and tested space software program, shoppers can obtain our planet-course FreeFlyer engineering assistance team, all with versatile licensing, resulting in the ideal value on the marketplace.
We’re seeing extra and much more LEO constellations. How can COTS providers meet the escalating needs of constellations?
When operating a satellite, flight dynamics jobs have to have to be carried out at specified intervals, these as preparing an upcoming maneuver or identifying attainable contact moments with an antenna on the Earth. It is common for FreeFlyer-primarily based operations to automate these tasks and make the ensuing details products obtainable. With a number of satellites, the processing time of these functions boosts, in some instances exponentially, for jobs this kind of as intra-constellation Collision Avoidance (CA). Floor units want to be ready to scale, and FreeFlyer is architected to accommodate that. FreeFlyer can distribute an full constellation’s flight dynamics duties across digital equipment or cloud occasions, generating products in parallel to reduce total run time. Our clientele with current or prepared constellation operations tell us FreeFlyer presents what they are looking for — flexible interfacing and scalability to meet up with their flight dynamics desires nowadays and in the upcoming.
Constellation providers typically program to start with a couple prototype spacecraft and develop to 50 or much more satellites. In these circumstances, automation and flexibility will have to go hand and hand. Several suppliers want a arms-on operator for the very first handful of satellites to get practical experience right before transitioning plan procedures to automation. We have also located that constellation companies need to have the adaptability to modify automation workflows more than time, re-operate unique jobs [if needed], and run throughout distinct components configurations — this sort of as solitary device, customer/server architecture, or at scale throughout virtual equipment or cloud scenarios.
a.i. solutions created our Meridian software package, which is driven by FreeFlyer, with these demands in intellect. It fulfills most regular LEO or GEO flight dynamics specifications with small configuration. Automated workflows create plan products and solutions: maneuver designs, speak to occasions, ephemerides, etc. Operators can see automated tasking and manually intervene if essential, enabling them to regulate many spacecraft from a single modern interface. a.i. solutions consistently develops new versions of our Meridian and FreeFlyer solutions with elevated features.
How does your software package scale to assistance operations of significant constellations with thousands or tens of 1000’s of satellites?
FreeFlyer’s overall flexibility and electric power helps make it uniquely suited to help assessment and operations for substantial constellations, in which automation and processing speed is of enhanced value. It is not sufficient to automate schedule functions, as even infrequent functions at this scale can outcome in a considerable workforce if they demand operator intervention. For example, an a.i. alternatives engineer works by using FreeFlyer to examine ascent and on-orbit functions of the Starlink constellation instantly. Orbit facts is ingested for each satellite as it gets to be available, managing a series of analyses that expose when a spacecraft deviates from its expected conduct, alerting the engineer. By only analyzing anomalous behavior, we decrease staffing, making it possible for us to emphasis on potential risks to other satellites.
Significant constellations have a dozen or far more satellites unfold out across a one orbit airplane. These orbit planes are organic grouping mechanisms for carrying out investigation and functions at scale. A single cloud instance of FreeFlyer can immediately carry out the essential flight dynamics tasks, these as preparing maneuvers to maintain suitable satellite spacing inside the plane. Conjunctions are feasible where by orbit planes overlap, and FreeFlyer can assess the possibility at these crossings with practical uncertainty in position and velocity. Different avoidance strategies can be swiftly devised and analyzed to reduce and successfully prepare for this hazard.

Another form of constellation on the rise is a cluster (or development) — a smaller number of cooperative satellites in close proximity. What exclusive worries are concerned with clusters?
The geometric relationship amongst cluster customers — their spacing, interactions, and in general cluster shape — is very sophisticated and must be constantly evaluated and predicted in operations. Our attempts with NASA’s record-placing Magnetospheric Multiscale development located classic CA methods ended up not legitimate for shut-traveling, low-relative velocity missions. We designed new methodologies using Graphics Processing Unit technological innovation to get hold of trusted CA outcomes on operational timelines. Developing on this, we created a cluster excellent aspect metric to statistically evaluate how mission performance will degrade or increase more than time, maneuvering satellites inside the cluster as required.
There are issues about how these huge constellations will impression place safety. How does a.i. solutions imagine the foreseeable future of space site visitors management?
a.i. solutions is committed to generating area safe and sound. FreeFlyer is currently employed for CA on dozens of missions, most notably the ISS. While FreeFlyer could conduct CA for all Area Visitors Administration as it moves from 18 SPCS to a civil company, a.i. solutions supports the Open Architecture Information Repository (OADR) thought, an open marketplace with various competing remedies. FreeFlyer’s API allows cloud-based mostly autonomous scripts to complete any portion of the CA assessment pipeline, depending on customer demands and options.
Additionally, a.i. solutions has developed a instrument identified as ObsSIM that gives simulated physics-centered place surveillance observations to aid well timed, effective, and practical tests, education, and true-time room workout routines. ObsSIM makes use of FreeFlyer to deliver simulated observations in the exact formats as stay facts, allowing for trainers to emulate an adverse condition, such as a separation or collision, that may possibly be infeasible to execute for an physical exercise or other coaching scenario. ObsSIM and resources like it can be the basis for simulations that aid operators educate on the OADR atmosphere.
