Abstract:	University of New Brunswick researchers have actively participated in the research community’s efforts to investigate the new GPS signal which is being broadcast by Block IIR-M satellites: the so called L2C signal. This participation has been carried out in several ways. UNB was one of the first institutions to have an active station participating in the International GNSS Service (IGS) L2C Test Network. UNB personnel have also contributed to the organization and management of the data, providing feedback to NASA’s Crustal Dynamics Data Information System (CDDIS), which is responsible for the L2C Test data archiving. UNB’s primary L2C station, which is called UNB3, has also been continuously used by several centers for different purposes, involving the modernization signal or not. However, perhaps the most substantial contribution from UNB for the L2C activities has been the research on the performance of the new signal, which has been carried out since early 2006. In this paper we present the latest results from our L2C signal analysis, which involves not only the investigation of the signal’s quality, but also the impact of its use on positioning.
