The aim of this assignment consists of studying orbit maintenance strategies for Low Earth Orbit (LEO) satellites, with STK. The need for an orbit maintenance strategy comes because of the perturbation forces that are applied to a satellite in orbit such as: J2 Earth gravity perturbation, lunar attraction, Sun attraction, atmospheric drag and solar radiation pressure. These forces separate the satellite from its original orbit so that it is necessary to apply correction manoeuvres in orbit, in order to keep the satellite within an acceptable trajectory window.

The Colorado Consortium of Earth and Space Science Education (CCESSE) has teamed up with AGI to enhance its Rendezvous with a Comet and Mars 2076 missions. They have created specific applications for the DATA officers to use in both the Space Station and Mission Control for these two missions. They also created pre-and post lessons for teachers to use to help prepare their students for the mission and to explain the science and math behind the application. The files contain the lessons, data logs and manual pages necessary to add this resource to a Challenger Learning Center (CLC) mission. CLC’s will also need to download the application, apply for an educator partnership with AGI and receive their licenses before they can begin using the product. The goal is to help the other Challenger Learning Centers to boost the DATA officer position, bring real-world applications such as STK into their missions and enhance the overall feel of the Comet and Mars missions.

Current CubeSat communication technology limits the amount of time and number of accesses with ground stations. It has been proposed to use a constellation of CubeSats to imporve relay performance and increase the number of accesses between a CubeSat and ground stations. By using the spatial and temporal analysis features of STK, coupled with the STK/Matlab interface, a robust tool was created to analyze the performance of CubeSat constellations based on a store-and-forward communications model.

DECOM Mission is designed to mitigate the Kessler Syndrome by actively removing five critical debris satellites per year during a five year mission life. Residing within the 800-1010 km altitude and 81-83 deg inclination band, the Cosmos Satellites, which use a Kaur-1 bus and weigh an average of 810 kg, are targeted due to their high collisional probability. The DECOM Robotic Arm (DRA) captures, despins, and disposes of the Cosmos satellite. Through mission heritage, the DRA can be modified to support removal of various debris types and future satellite servicing. A NEXT Electric Propulsion engine, powered by UltraFlex solar arrays, performs debris transfer and orbit lowering down to an altitude of 635 km, where the debris will be released assuring reentry within 25 years. The mission takes advantage of differential precession between DECOM at the disposal altitude and the next debris target altitude to achieve plane changes in right ascension, minimizing mission ΔV.

QB50 is a network of 50 CubeSats in a string of pearls configuation that will be launched in mid April of 2015 by a single launch vehicle into a circular orbit at 320 km altitude. Some of the CubeSats for In-Orbit Demonstration will carry a set of standard sensors to conduct multi-point, in-situ, long duration measurements of key parameters and consitutents in the largely unexplored lower thermosphere and ionosphere. Because of the density variations along the orbit, deployment directions, deployment frequencies, deployment sequences and differences in the ballistic coefficient of the CubeSats, the separation distance between the CubeSats will change, leading eventually to a non-uniform distribution of the CubeSats. This paper seeks to minimize the risk of collision between the 2U CubeSats and maximize the distribution of 2U CubeSats all the way around the Earth. The project goal is to provide an optimized deployment scenario. To obtain this paper, email VKI Library directly at biblio@vki.ac.be and request the report (document id SR201227).

Durch die zunehmende Bedrohung der Piraterie auf den Haupthandelsrouten der Schifffahrt und der derzeitig sehr uneffizienten und lückenhaften Überwachungsmethoden ist es unabdingbar satellitengestützte Monitoring ‐ Maßnahmen zu entwickeln. Hauptziele dieser Mission sind: eine lückenlose Überwachung der Erdoberfläche im Bereich von 20° nördlicher Breite bis 5° südlicher Breite sowie von 40° östlicher Länge bis 60° östlicher Länge (Haupthandelsrouten der küstennahen Bereiche im Indischen Ozean), Warnung bevorstehender Angriffe und die Informationsweitergabe an das Militär. Dadurch ist es möglich Schiffe rechtzeitig vor Piraten zu warnen und strategische Aktionen seitens des Militärs und des Küstenschutzes besser zu koordinieren und zu planen. Des Weiteren könnte man mit Hilfe dieser Mission noch die Einhaltung globaler Schifffahrtsrechte kontrollieren. Diese Mission richtet sich an alle Staaten und Reedereien, die Schiffe auf dem Indischen Ozean haben und an die Forschung.

Paper, slides and poster on the EXOCUBE mission. The EXOCUBE mission is designed to acquire global knowledge of the in-situ densities of the major species in the ionosphere and neutral upper thermosphere and lower exosphere. Specifically, the Neutral and Ion Static Energy Angle Analyzers (NSEAA and ISEAA) and the Total Ion Monitor (TIM) on board Exocube will make measurements of [O], [H], [He]. [N2], [O+], [H+], [He+], [NO+], and total ion (and thus electron) density. By providing benchmark measurements over Arecibo, Wisconsin, Kitt Peak, and Cerro Tololo, EXOCUBE aids in the validation and inter-comparison of ground-based observations from these sites using passive optical inteferometery and photemetry of neutral airglow emissions as well as active incoherent scatter radar to characterize the local ionosphere. In this study, we outline some of the science objectives that can be addressed with these measurements along with the instrumental and observing requirements for these investigations.

The slides are grouped into daily lessons and cover 3 basic areas: •The educational aspect of Orbit Determination: a review of the basics, ( accompanies Chapter 10 of Fundamentals of Astrodynamics and Applications.) The objective is to have the students just “see” what an operational tool can do. •The second part is an intro into the ODTK software . It talks about what it does, in terms that were introduced in part 1. •The last part is an expanded section that looks at various applications. The idea is to get students to know OD, understand how ODTK basically works, and then get them pushing buttons and seeing it in operation, using real-world data to show students that virtually nothing comes out as planned.

This thesis describes the approach to designing a Low Earth Orbit CubeSat constellation capable of nearly constant coverage. The software package STK is used to create simulated multi-satellite systems that maintain a communication link between Tenby, Pembrokeshire, Wales and tactically chosen locations in the United States of America. The research will attempt to find the constellation capable of maintaining a set of design parameters (such as signal to noise ratio and altitude), with the minimum possible number of CubeSats. The downlink location, antenna design and the orbital planes are the negotiable parameters in the system, with little to no set constraints, and thus will be altered until the most favorable system is successfully designed.

Earth observation satellites have emerged as the preeminent tool for consistent and high-resolution imagery. The eyeON mission is designed to provide rapid on-demand sub three meter resolution imagery as well as generate a database of regions of interest. In this document, the eyeON team proposes a multi-use satellite observation system capable of servicing many constituents in different areas of study. The constellation of five satellites in a walker orbit enables the entire Earth to experience an overflight within a 24-hour period. This short revisit rate carries distinct advantages over other systems when the satellites are tasked with capturing images of disaster-affected areas. The quick response time of one day enables the distribution of level 3 image products to the customer within one day of request to image. The combination of high optical and temporal resolution provides the eyeON mission with distinct advantages over existing missions.

Ever wonder what satellites are flying above your head when you look up? This app will show them to you using augmented reality. Point your phone's camera to the sky, and small icons track the locations of various satellites. For many, a line indicates their projected path across the sky. Those flying in sunlight are labeled in yellow, and those in the shadow of the Earth or Moon, in blue. This yellow and blue coloring is useful to casual observers who go out looking at the night sky for satellites. Typically, those in shadow (blue) are not visible at all, while satellites in Sun (yellow) may be visible even to the naked eye, depending on size, altitude, and other factors. The best time to spot satellites is often just after dusk or just before dawn, when the Earth's shadow is at a steep enough angle from the observer's point of view that the satellites above are still lit by direct sunlight. The app also contains a simple star map. The brightest 2000 stars are shown as white dots on the screen, to help the user align the app's display with the sky above.

A student paper analyzing the effects of wind turbines on radars and postulating solutions for these interferences. Abstract—Wind power plant installations at different scales are in an increasing pattern starting from year 2000. A curiosity has been raised about 4-5 years ago for if wind turbines interfere with radars. The interference occurs when wind turbines reflect radar waves and cause missing targets and blind regions on radar images. Doppler radars are most used to discriminate between the return from a desired target and that from undesired objects, usually ground clutter. There are so many resulting effects of interference such as shadowing, damage to radar equipment, larger radar cross section (RCS) and missing desired targets, etc. Both radar and wind power plant mitigations are available. But still, there is no overall solution, only case by case treatment. RADAR is an acronym for RAdio Detection And Ranging, it will be used as “radar” throughout this paper. Paper presented at IEEE Conference and is available through the IEEE Computer Society Digital Library (CSDL): http://www.computer.org/portal/web/csdl/abs/proceedings/uksim/2012/4682/00/4682toc.htm

The main scope of the mission is the rapid mapping of the world’s tropical regions, with a primary focus on the Amazon basin. This is accomplished by the satellite’s low orbit inclination allowing multiple data pass times over the tropical areas, mitigating the inherent cloud coverage problem. The mission is designed for five years of nominal operations with a tentative launch date in 2014.

This paper discusses the use of solar radiation pressure augmented deorbiting to passively remove small satellites from high altitude Sun-synchronous orbits. It is shown that passive solar radiation pressure deorbiting is a useful alternative to propulsive end-of-life manoeuvres for future high altitude Sun-synchronous missions.

This project aims to validate an analytical model of the orbital evolution of microsatellites by comparing an implementation in MATLAB against high fidelity STK propagations. The model is based on analytical equations derived by Krivov et al. (1995) that describe the secular perturbations of dust particle orbits about Mars due to solar radiation pressure (SRP) and the J2 effect.

STK Scenarios: 1-Scenario serves the determination of launch opprtunities and communication windows of the TUM MOVE cubesat. STK is used to calculate orbit passes of different weather satellites over the institutes ground station. Using the STK scenario helps to schedule suitable passes for ground stations tests and system verification. 2-STK is used for the evaluation of different communication architectures for real-time teleoperations. The Main GUI is programmed in Matlab configuring different communication infrastructures and creating reports about access times and physical propagation path length. In a second step, an analysis of the link performance will be implemented. To achieve a high fidelity simulation of the communication path the QualNet UI Plugin is used allowing packet simulations. STK was used to propagate the distributed communication system elements (teleoperator, ground station human operator) allowing an evaluation of optimal communication architectures.

Detailed excerpt of simulations and experimental results in a final project of a picosatellite project. Simulations have been made for three different cases depending on the positioning of the orbit relative to the Sun, when the orbit is a significant parameter of the simulation. Since one of the most common orbits for the CubSat mission is the Sun-synchronous, the three most representative Sun-synchronous orbits are analyzed. Includes step-by-step directions to perform the simulations.

With WunderSat the world gets enriched by a very-low-cost, optical moderately high resolution mission, mainly designed for the low-budget farming market - designed for feeding the World. Given the primary importance of this mission to both very low-cost efficiency and frequent availability, the system is serving the need of satellite imagery for every-day applications especially in the field of agriculture and farming. In contrary to previous and existing missions, WunderSat is designed for a different customer range, adressing for the first time also the comparatively small farmers and private sector and thus bringing the use of satellite imagery to the people of this world.
