GNSS Activities and Performance at USNO

Abstract

This paper presents selected recent GNSS activities in the Time Service Department at the U. S. Naval Observatory in Washington, DC. Items investigated include relative receiver calibration; evaluation of the recent performance of GNSS receivers; zero-age corrections applied to operational PPS receiver data to compute a better one-day value for the USAF; a brief presentation of an algorithm to detect and correct discrete jumps in time-series data including the potential applications; applications of PPP for GPS time transfer as well as the ability to determine receiver instability through common-antenna, common-clock PPP solutions; GPS Time Transfer Trips; USNO's contributions to the IGS MGEX; and progress on GPS-to-GNSS Time Transfer (GGTO).
