Abstract
Very Long Baseline Interferometry (VLBI) is a method for observation of extragalactic radio sources which appears to have potential for precise long-distance Earth surveying, clock synchronization and spacecraft navigation. For the past several years, many researchers at JPL and elsewhere have been working to establish the accuracy of VLBI observations. The intent of the work reported here has been to review the principal components of the VLBI instrument in order to estimate and/or bound the systematic error contributions. In this first of a series of articles, we establish the definitions and tools which we need in order to apply filter transfer-function analysis to the VLBI receiver, and we use it to estimate the sensitivity of the VLBI receiver to plausible filter variations.
