Determinants of Moral Attitudes
Journal for the Scientific Study of Religion, 1988Contemporary controversies over abortion, pornography, homosexual rights, family relations, and prayer in school pit traditional moral conservatives against modern liberal relativists. Prior analyses, especially status politics interpretations, are regularly biased by presuming liberal relativist attitudes and treating moral conservatism alone as ...

Optimal REQUEST algorithm for attitude determination
AIAA Guidance, Navigation, and Control Conference and Exhibit, 2001REQUEST is a recursive algorithm for least-squares estimation of the attitude quaternion of a rigid body using vector measurements. It uses a constant, empirically chosen gain and is, therefore, suboptimal when filtering propagation noises. The algorithm presented here is an optimized REQUEST procedure, which optimally filters measurement as well as ...

Instantaneous GPS attitude determination
IEEE PLANS 92 Position Location and Navigation Symposium Record, 1992The author describes a procedure for instantaneous GPS (Global Positioning System) attitude determination, i.e., a solution for the GPS integrated carrier Doppler wavelength ambiguities using only measurements at a single epoch. Most previous techniques for solving the phase ambiguity problem have required some form of time history processing relying ...

Attitude Determination via GPS
1991The principles of attitude determination using the Global Positioning System (GPS) are described. The specific techniques which can be used to resolve the initial carrier phase ambiguities which arise when the antennas are more than one-half wavelength apart are also described.

Unisat-3 Attitude Determination
2005UNISAT program was established at the Scuola di Ingegneria Aerospaziale of University of Rome “La Sapienza” in late nineties. In the framework of this project Professors, researcher and students of GAUSS (Gruppo di Astrodinamica dell’Università degli Studi “La Sapienza”), coordinated from Professor Filippo Graziani, have already designed, manufactured
