Satellite Orbits
This modern presentation guides readers through the theory and practice of satellite orbit prediction and determination. Starting from the basic principles of orbital mechanics, it covers elaborate force models as well as precise methods of satellite tracking. The accompanying CD-ROM includes source code in C++ and relevant data files for applications. The result is a powerful and unique spaceflight dynamics library, which allows users to easily create software extensions. An extensive collection of frequently updated Internet resources is provided through WWW hyperlinks.
Satellites
This useful resource deals with satellite orbits, showing how the wide range of available orbits can be used in communications, positioning, remote-sensing, meteorology, and astronomy.
Eccentric Orbits
“Good corporate drama . . . an enlightening narrative of how new communications infrastructures often come about.” —The Economist, “A Book of the Year 2016” In the early 1990s, Motorola developed a revolutionary satellite system called Iridium that promised to be its crowning achievement. Its constellation of 66 satellites in polar orbit was a mind-boggling technical accomplishment, surely the future of communication. The only problem was that Iridium the company was a commercial disaster. Only months after launching service, it was $11 billion in debt, burning through $100 million a month and crippled by baroque rate plans and agreements that forced calls through Moscow, Beijing, ...
God Save the Queen
The first in an alternate fantasy series where vampires, werewolves, and goblins rule London. Queen Victoria rules with an immortal fist. The undead matriarch presides over a Britain where the Aristocracy is made up of werewolves and vampires, where goblins live underground and mothers know better than to let their children out after dark. It's a world where the nobility are infected with the Plague (side-effects include undeath), Hysteria is the popular affliction of the day, and leeches are considered a delicacy. And a world where technology lives side by side with magic. The year is 2012 and Pax Britannia still reigns. Xandra Vardan is a member of the elite Royal Guard, and it is her duty to protect the Aristocracy. But when her sister goes missing, Xandra will set out on a path that undermines everything she believed in and uncover a conspiracy that threatens to topple the empire. And she is the key -- the prize -- in a very dangerous struggle. The fantastic start to The Immortal Empire series that continues with the spectacular undead books, The Queen is Dead and Long Live the Queen.
The Great Witch of Brittany

Brittany, 1741: There hasn't been a witch born in the Orchière clan for generations. According the elders, that line is dead, leaving the clan vulnerable to persecution. Ursule Orchière has been raised on stories of the great witches of the past. But the only magic she knows are the false spells her mother weaves over the women who visit their fortune-telling tent. All of that changes when Ursule comes of age and a spark of power flares to life. Thrilled to be chosen,...
Wild and Wicked Things
"Haunting, immersive, and seething with dark magic."―Alexis Henderson Oprah Daily Top 25 Fantasy Book of 2022! In the 1920s, a lush, decadent gothic tale unfolds as a young woman slips into a glamorous world filled with illicit magic, tantalizing romance, and murder. On Crow Island, people whisper that real magic lurks just below the surface. But magic doesn’t interest Annie Mason. Not after it stole her future. She’s on the island only to settle her late father’s estate and, hopefully, reconnect with her long-absent best friend, Beatrice, who fled their dreary lives for a more glamorous one. Yet Crow Island is brimming with temptation, and the most mesmerizing may be her enigmatic n...
The Fallen Blade
Venice, 1407. The city is at the height of its powers. In theory, Duke Marco commands, but Marco is a simpleton so his aunt and uncle rule in his stead. They seem all powerful, yet live in fear of assassins better than their own. On the night their world changes, Marco's young cousin prays in the family chapel for deliverance from a forced marriage. It is her misfortune to be alone when Mamluk pirates break in to abduct her - an act that will ultimately trigger war. Elsewhere Atilo, the Duke's chief assassin, cuts a man's throat. Hearing a noise, he turns back to find a boy drinking from the victim's wound. The speed with which the angel-faced boy dodges his dagger and scales a wall stuns Atilo. He knows then he must hunt him. Not to kill him, but because he's finally found what he thought was impossible - someone fit to be his apprentice. Award-winning author Jon Courtenay Grimwood is a master storyteller. Here, he blends history, politics and dark fantasy in a compelling vision of an alternative Venice.
The Justice of Kings
'A stunning piece of modern fantasy writing' RJ Barker 'Utterly compelling, thoroughly engrossing and written with such skilful assurance I could barely put it down' Nicholas Eames NO MAN IS ABOVE THE LAW The Empire of the Wolf simmers with unrest. Rebels, heretics and powerful patricians all challenge the power of the imperial throne. Only the Order of Justices stands in the way of chaos. Sir Konrad Vonvalt is the most feared Justice of all, upholding the law by way of his sharp mind, arcane powers and skill as a swordsman. At his side stands Helena Sedanka, his clerk and protégé, orphaned by the wars that forged the empire. When the pair investigate the murder of a provincial aristocrat,...
Theory of Orbit
Theory of Orbits: The Restricted Problem of Three Bodies is a 10-chapter text that covers the significance of the restricted problem of three bodies in analytical dynamics, celestial mechanics, and space dynamics. The introductory part looks into the use of three essentially different approaches to dynamics, namely, the qualitative, the quantitative, and the formalistic. The opening chapters consider the formulation of equations of motion in inertial and in rotating coordinate systems, as well as the reductions of the problem of three bodies and the corresponding streamline analogies. These topics are followed by discussions on the regularization and writing of equations of motion in a singu...
Handbook of Geostationary Orbits
This Handbook 0/ Geostationary Orbits is in principle an extension of the Introduction to Geostationary Orbits that was printed as a special publica tion by the European Space Agency (ESA) in 1983. The immediate purpose was to provide the theoretical background and some practical advice for the orbit control of geostationary spacecraft by means of the software package "PEPSOC". PEPSOC, short for "Portable ESOC Package for Synchronous Orbit Con trol" , was produced by the European Space Operations Centre (ESOC) to support spacecraft operations in the routine phase. The resulting publication was a handbook for engineers and spacecraft operators, rather than a clas sical textbook in celestial m...
