Abstract:

In the experimental mobile inertial survey system, geodetic parameters are measured relative to an origin point. Certain errors build up along the survey course. Typically, these errors are adjusted and distributed both during and after completing each mission. During testing, the adjusted derived data are compared with known data that are determined by conventional classical surveys. In its research, ETL requires a more accurate adjustment of errors obtained from conventional methods. The approach to the problem involved evaluating and analyzing the various error sources in the conventional data recalculation of certain data by new methods and developing a new statistical error treatment that applies not only to the objectives of this in-house research, but to the general application of inertial geodetic systems. In this report, a new statistical error procedure has been developed to improve geodetic positions that are useful in ETLs core program of RGSS tests and in any future tests of inertial systems.
