Modern space sector innovations are making space access more affordable and technologies more ubiquitous. Space Domain Awareness (SDA)–the ability to monitor, understand and predict natural and man-made objects in orbit around the Earth–is more important than ever. The ExoAnalytic Global Telescope Network (EGTN) is a global commercial SDA telescope network with more than 25 observatories and 275 telescopes tracking man-made space objects in multiple orbit regimes. Our telescopes regularly detect, track, and correlate objects in geosynchronous Earth orbits (GEO), highly elliptical orbits (HEO), and medium Earth orbits (MEO). The EGTN passively collects both angles and brightness measurements (RA/DEC and apparent magnitude) that can be provided in commercial bulk or as part of a focused service.

ESpOC technology supports any optical sensor design configuration and has been used on more than 100 different telescope and camera configurations. The ESpOC Operator Package turns any telescope into a powerful and responsive SDA system. Telescopes running ESpOC have automated image registration (position accuracy), image calibration (brightness accuracy), man-made space object detection (find all objects), object correlation (know what they are), catalog maintenance (know where they are), and orbit updates (know where they are going).

ESpOC enables the efficient and effective allocation of sensor resources to provide rapid space situational awareness, and to rapidly recommend appropriate operator responses to events in space. Our ESpOC sensor status suite (ESpOC S3) provides real-time observatory and sensor availability and performance conditions. ESpOC Task Manager is a dynamic sensor tasking algorithm that delivers tasking via machine-to-machine interface for all network sensors. Our Ontological Sensor Management and Adaptable Real-Time Tasking (O-SMART) module, developed for the Missile Defense Agency, optimizes tasking across the detect, track, characterize process while adaptively responding to changing priorities.

Our powerful catalog tools autonomously correlate known tracked objects to objects in our database containing identifying information (e.g., satellite number, common name, etc.).  For unknown objects (i.e. objects that cannot be correlated to a catalog), we perform an initial orbit determination and maintain the objects as uncorrelated tracks (UCTs). BruteStack is our UCT discovery tool that provides track-to-track association and outlier rejection. BruteCorr provides tracklet to catalog correlation, multi-sensor correlation, and ambiguous track processing.

Our industry-leading orbit determination tool, EigenOrbitFitter, provides high-fidelity batch fit orbit determination using 2-D line of sight measurements to produce an orbit estimate in the form of 3-D position and velocity vectors and a 6×6 covariance matrix. EigenOrbitFitter has been validated against WAAS satellite truth orbits with <10m error near GEO, and has been used to discover momentum impulse changes as small as ~1mm/s.

The first question we are asked each time we work with any company or government organization is, “how good is your data?” Simply put, we produce the most accurate data available commercially. Our data has been independently validated by numerous defense, civil, and intelligence agencies as well as by many commercial companies.

ExoAnalytic has a variety of data collection and delivery services to meet our customer’s needs. Customers wanting to develop their own catalogs utilize our Tiered Subscription services that consist of many telescopes distributed globally that provide data utilizing a variety of search and survey routines. Other customers are only interested in a few satellites (typically their own) and utilize Individual Telescope tasking to direct our collections. Our data collection services are tailored to each customer’s needs and include automated delivery as well as training on the use of our data with their in-house tools.

ExoAnalytic maintains a complete historical archive of our 100 million+ metric and non-metric object measurements within our SpaceFront data archiving and analytics engine. SpaceFront is a web-browser based Graphical User Interface (GUI) that allows a user to access and analyze historical ExoAnalytic data.

As operators of the world’s premier SDA telescope network, ExoAnalytic Solutions is uniquely positioned to support a wide variety of space industry needs. Our team of professionals offers custom solutions for satellite operations throughout the spacecraft lifecycle. These services include launch monitoring, conjunction analysis, warning and secondary screening, anomaly detection and resolution. We also regularly provide customized services designed to help satellite operators ensure safety and cost-effectiveness.
