Brightness of the sky background due to lunar phase and location can dramatically affect the limiting magnitude of astronomical detectors. Formerly, theoretical models have attained limited data sets with 10-20% differences between model and observation. This paper compares and contrasts previous investigations with over a million data points collected from various GEODSS sites located around the world, and attempts to refine predictive modeling of sky brightness for use in scheduling, as well...

Effective space situational awareness (SSA) requires horizon-to-horizon surveillance of the sky, twenty-four hours a day, seven days a week. In practice, the amount of sky over which high-resolution images of space objects can be obtained using the Air Force's large aperture telescopes is limited to regions where the combination of adaptive optics (AO) compensation and numerical image restoration have good performance. For current AO systems and image processing techniques this is achieved for...

Space Situational Awareness (SSA) is a growing concern for National Security. Among the many methods of increasing SSA is the use of space-based Laser Imaging, Detection And Ranging (LIDAR) sensors to detect, track, classify or image other spacecraft. This Thesis explores the unique trade-spaces and design decisions faced by an engineer designing such a system. It provides an overview of the basic operational principles, the major components, the impact of one design choice on all other...

A hybrid genetic algorithm is described for performing the difficult optimization task of resolving closely spaced objects appearing in space based and ground based surveillance data. This application of genetic algorithms is unusual in that it uses a powerful domain-specific operation as a genetic operator. Results of applying the algorithm to real data from telescopic observations of a star field are presented.

The activities in Year 2 have followed two main research directions: The development of a new point-spread function (PSF) reconstruction approach which aims at extracting, from multi-frame observations, a number of PSFs at several locations within an image of an arbitrary object (without point sources). The development of a marginal blind deconvolution estimator, combined with constraints on the observed object such as positivity, for identification of long-exposure adaptive optics PSFs. This...

The need for precision in space surveillance and space control continues to grow as both the number of satellites increases and the importance of space debris tracking elevates. Improvements in instrumentation, from detection devices to pointing hardware, is one area where precision is being increased. Once data acquisition is made, reduction software comes into play. Regardless of the precision in that software, a priori information, such as stellar positions and magnitudes, can degrade the...

Since the launch of satellites into Earth orbits more than 50 years ago, space has become crowded. Commercial and military satellites, both active and defunct, share the space environment with an assortment of space debris, such as remnants of damaged spacecraft and spent rocket boosters. This profusion of orbiting objects could seriously threaten space assets, such as the International Space Station or NASA s science missions such as the Hubble Space Telescope. Moreover, the global...

This award has allowed to develop a new, mathematically sound algorithm of the blind image deconvolution, which demonstrates a superior performance when compared with existing techniques. The concept change in our approach to blind image deconvolution is in the basic strategy of addressing sensible approximate solutions to the ill-posed nonlinear inverse problem. These solutions are addresses as fixed points of the iteration which consists in alternating approximations (AA) for the object and...

In this chapter, we consider the sensor management problem for tracking space targets where the targets may apply evasive maneuvering strategy to avoid being tracked by the space borne observers. We first study the case of single target tracking by a single observer and formulate the pursuit evasion game with complete information. Then we extend the tracking problem to a set of collaborative observers and each observer has to decide when to sense which target in order to achieve the desired...

The current targeting cycle used by the services relies heavily upon the use of space assets. The Global Positioning System (GPS) and satellite communications are just a few of these assets accessed thousands of times a day. With technology growing by leaps and bounds, it is a challenge for tactical and operational commanders to keep up with the growing capabilities offered by space-borne platforms. Having this in-depth knowledge can assist in all facets of combat, from the best time to attack,...

Requirements for a space surveillance system are now being generated by the various unified and specified commands. While details remain to be determined, in general it may be stated that the requirements express a need for three categories of coverage: (a) early detection, (b) coverage of low inclinations, and (c) coverage at extreme altitudes. A minimum-cost, space surveillance system which provides early orbit determination of all satellites out to nearly 30,000 nautical miles is described....

A new operating mode for imaging satellites has been developed. The non-imaging mode is designed to provide high temporal resolution data time varying targets. The idea is to use linear pushbroom arrays with kilohertz sampling rates to not only detect, but also measure the frequency of temporally varying targets. For satellite operations this will involve satellite slewing at a rate which cancels the effects of satellite orbital motion. This concept was explored here with a laboratory...

The computational complexity of track initiation, also known as initial orbit determination or IOD, using only angle measurements is polynomial in the number of observations. However, the polynomial degree can be high, always at least cubic and commonly quartic or higher. Therefore, practical implementations require attention to the scalability of the algorithms, when one is dealing with the very large number of observations from large surveillance telescopes. We address two broad categories of...

In the context of the surveillance of space, known resident space objects (RSO), i.e. active satellites and space debris, need to be acquired periodically to ensure that the knowledge of their orbital parameters is up-to-date. The most sensitive observation method consists of acquiring an image sequence while the target is actively tracked by the optical system such the RSO appears stationary in the image sequence. This generates an incredible amount of data which requires efficient detection...

The problem for efficient use of radar assets for space surveillance is unsolved. Partial solutions have been developed, such as covariance based tasking algorithms, but not all operational requirements for tracking support are quantified by accuracy, for example monitoring a non-cooperative maneuvering satellite for purposes of conjunction assessment. The following effort exposes a different approach, where competing requirements, each with quite different metrics, can compete for sensor...

The Clementine story began in 1990 when NASA administrator Richard Truly asked the Department of Defense to consider a joint NASA/DoD mission that would achieve goals mutually beneficial to both organizations. That request was given to the then Strategic Defense Initiative Organization (SDIO) to investigate. A mission was conceived to test the latest in space-based imaging components, using the Moon and a near-Earth asteroid as celestial targets. The Clementine mission is the result of those...

Data association for Uncorrelated Tracks (UCTs) is a persistent and difficult problem in Space Situational Awareness. Space objects (SOs) often maneuver or are perturbed between observations, and when new measurements are collected, these new UCTs not always easily correlated with existing catalog objects. Presently, orbit element gating, Euclidean distances, and Mahalanobis distances are considered in the literature as tools with which UCTs may be appropriately associated. This Final Report...
