The ideal candidate should possess a keen visual understanding and knowledge of quality control and ASO-9100 standards with close attention to detail and origination skills. Reporting to the Production Supervisor, the AIT Technician will be responsible for manufacturing sub-assemblies of spacecraft.

Terran Orbital Corporation is seeking an experienced AIT Technician (Weekend Shift). We are a unique, fast-growing, and trusted team focused on quickly and economically designing, building, launching, and operating state-of-the-art satellites for advanced mission constellations. We are a pioneer in the miniaturization of space technologies and the delivery of responsive space solutions. Applications of this work for international space policymaking, including the development of on-orbit norms of behavior and the distribution of spectral and physical space in GEO, is also discussed.Be more than an employee number! Join Terran Orbital, the leader in innovation, manufacturing, and operations in the small satellite industry. Identifying anomalous satellite behavior is of critical interest to space situational awareness (SSA) system operators, who may choose to task their sensors to obtain more observations of anomalous behavior, and satellite operators themselves, who may wish to diagnose its root cause.

In this work, a satellite’s behavior is considered nominal if it adheres to the satellite’s pattern of life (PoL)-its previous on-orbit behavior made up of sequences of both natural and non-natural behavioral modes, including routine station-keeping, other on-orbit maneuvers, and uncontrolled motion-and anomalous if it deviates from the satellite’s PoL. When detected, longitudinal shift maneuvers can be used to identify anomalous behavior in GEO. Performance metrics are presented for algorithms trained on two different training data sets corresponding to five and ten years’ worth of geographic position time-histories labeled with longitudinal shift maneuvers. A preliminary maneuver detection algorithm is designed, trained, and tested on all GEO satellites in orbit from January 1 to December 31, 2020. A method for converting TLE data to geographic position histories-longitude, latitude, and altitude positions over time in the Earth-centered, Earth-fixed geographic reference frame-and labeling longitudinal shift maneuvers by inspection is described. Space Command’s (SPACECOM) space object catalog. This work describes an approach for detecting the components of longitudinal shift maneuvers-including the patterns associated with initiating and ending eastward and westward drifts-using convolutional neural networks trained on publicly available two-line element (TLE) data from the U.S.

Such a maneuver often requires both a series of impulsive thrusts and a period of natural drift. One such maneuver is a longitudinal shift: changing a GEO satellite’s sub-satellite point from one position on the Earth’s equator to another.

Less frequently, GEO satellites perform maneuvers to alter their orbital characteristics more drastically. To maintain their position relative to the Earth’s surface, GEO satellites must station-keep, or regularly expend onboard propellant to counteract the natural forces in the near-Earth space environment that perturb their orbital trajectories. This unique orbital characteristic makes GEO satellites ideal for telecommunications missions that require Earth-fixed antennas to send and receive signals, such as television broadcasts or military communications. Due to the nature of the geosynchronous (GEO) orbital regime, where space objects orbit the Earth once per sidereal day, GEO satellites can appear fixed to a position in the sky when observed from the Earth’s surface.
