Scientific paper
A series of numerical experiments simulating angular observations with a scanning astrometry satellite, and the subsequent reconstitution of the celestial sphere, is shown to demonstrate the determinability of (1) relative positions and (2) absolute trigonometric parallaxes, for a network of stars covering the entire sky, after only one year of observation. The experiments confirm previously estimated variations of the astrometric accuracy, with ecliptic latitude and basic mission parameters such as length, revolving angle, and number of stars observed. Support is also given for a simple formula by which the overall accuracy as a function of such parameters may be estimated. The study is pertinent to performance projections for the Hipparcos satellite project.
