|
| It is inevitable that humankind will weaponize space and equally likely that this will take place in the next 30 years. The United States is in the early stages of a transition from using space assets to support combat operations on the surface of the earth to using space assets to conduct combat operations in space, from space, and through space. This paper discusses factors driving the United States to ... |

|
 | Satellite communication applications are continuously searching for ways to either reduce earth terminal antenna size or increase the data rate of the communication link. The Tracking and Data Relay Satellite System (TDRSS) space deployable mesh antennas provide an alternative for increased satellite antenna gain. The TDRSS space-to-space link uses a 4.8 meter diameter deployable mesh antenna. Harris Corporation delivered two deployable antennas for each of the six TDRSS satellites built ... |

|
| Today's space law environment consists of a number of general positions. The United States believes in space use by all states for peaceful purposes and supports laws that will not hinder national security or peaceful progress. Defensive, nonaggressive military activity is not precluded. To the Soviet Union, space is an extension of the terrestrial environment, subject to the same political and military realities associated with the continuing struggle between capitalism ... |

| Authors:
L. W. Maddox; AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH SCHOOL OF ENGINEERING
|
| A flexible method was developed to optimize electric orbit transfer vehicles (EOTVs) and compare them with baseline chemical systems. EOTVs have been characterized by the thruster technology and the propellant mass versus power supply mass for standardized NASA BIMOD configurations. Baseline chemical systems are represented by the Inertial Upper Stage CENTAUR-G, and a proposed reuseable LOX-LH Centaur derivative. Five electrostatic propulsion thrusters were chosen for optimization. These were the baseline ... |

George E. Morduch; OLD DOMINION SYSTEMS INC GAITHERSBURG MD
|
| The Fotonap program has been modified (i) to include the option to compute the desired solution without inverting the normal equations matrix (thus not obtaining the solution covariance matrix), and (ii) to include the capability to handle Geoceiver measurements. For a typical run involving photogrammetric data, implementation of item (i) reduced the time taken to obtain the normal equations solution from 1 hour 50 minutes to 20 minutes. Two types ... |

|
| The LES-8 and -9 satellites are three-axis stabilized earth-orbit spacecraft which provide communications at UHF and K-band frequencies with the capability of simultaneously establishing and automatically maintaining a K-band (36-38 GHz) satellite-to-satellite data link. The inter-satellite data crosslink extends the earth coverage over that which a single satellite can provide and demonstrates how a global communications system might be realized without the restrictions imposed by ground relay. This report describes ... |

|
| Range rate data between two satellites can be used to determine acceleration along the connecting line between two satellites by numerically differentiating an analytic representation of this data. Using a reference potential field this acceleration can be interpreted to be a derivative of the disturbing potential along the line of the satellites. Using geometric techniques, the radial component of the disturbing potential can be estimated. This component can then be ... |

L. A. Hoffman; AEROSPACE CORP EL SEGUNDO CA LAB OPERATIONS
|
| Applications for millimeter waves are discussed, and it is shown how propagation effects enter into systems considerations for the EHF region. The state of the millimeter-wave art is reviewed as to antennas, sources, amplifiers, and receivers. Highlighted are two applications, a high-resolution radar, which it is hoped can utilize the inherent advantage of the short millimeter wavelengths for resolution, and a space-to-space communication system at EHF. |

| Authors:
R. A. Rollin Jr.; F. Zwas; MICHIGAN UNIV ANN ARBOR INST OF SCIENCE AND TECHNOLOGY
|
| Space-to-space and earth-to-space communications systems with currently available laser sources have been studied and analyzed. Conclusions are drawn concerning the best continuous wave (CW) laser wavelength for both types of systems under various conditions, and areas of research are recommended. The general optical-communications range equation was derived using signal to noise considerations for the space-to-space and earth-to-space systems. The performance of seven laser systems employing state of the art components ... |

|
| A simple technique is presented for obtaining the optimum frequencies for communication with a low-altitude satellite, no higher than 800 nautical miles. The output signal-to-noise ratio at the receiving station is expressed in terms of as many parameters as possible with their respective frequency dependence. The optimum frequency is obtained by a maximization process. In cases where the exact frequency behavior of the process is too complex, an approximate analytical ... |

|
| Laser communication techniques are presented that can be integrated into the AIRCOM System to satisfy unmet current and estimated future AF requirements. The advent of the laser has aroused great interest among communication engineers because it affords use of a new spectrum millions of megacycles wide. Although the laser will have a great impact in certain areas of communications technology, its potential in any specific area must be carefully evaluated. ... |
