DOWNLOAD 3 MB	U.S. Systems Status and Service Provision Anthony Russo, National Coordination Office This plenary presentation includes three sections covering: U.S. space-based PNT policy implementation; GPS technical information and modernization plans; and U.S. augmentation systems.
DOWNLOAD 1.6 MB	GPS Civil Interface Observations Rick Hamilton, Coast Guard Navigation Center This briefing, presented during a plenary session, describes the Navigation Center's recent experiences in dealing with user equipment that does not comply with GPS Interface Control Documents and user feedback on the NANU process used to disseminate GPS status information. It describes the Notice to All Navigation Users (NANU) format and suggests that other GNSS providers use it to broadcast their own status reports.
DOWNLOAD 3.5 MB	Enabling Multi-Constellation Advanced Receiver Autonomous Integrity Monitoring (ARAIM) Leo Eldredge, Federal Aviation Administration This presentation provides an overview of the FAA's investigations into ARAIM as a possible method of ensuring GPS integrity in aircraft without external augmentation systems. The use of multiple frequencies and multiple GNSS constellations could make this feasible in the future, if the right information becomes available from the GNSS providers.
DOWNLOAD 615 KB	Template for GNSS Service Performance Commitments Karl Kovach, contractor to U.S. Air Force This briefing, presented during the Providers Forum, describes how the United States documents its GPS performance commitments to the public. It encourages other GNSS providers to use the same formats to document their own service commitments.
Coming Soon	DHS Progress with the PatriotWatch Program Rick Hamilton, Coast Guard Navigation Center This briefing, presented during the Providers Forum, describes a U.S. effort to detect and mitigate interference to GPS.
DOWNLOAD 3 MB	Seamless GNSS Through Integrated User Equipment: A Joint Evaluation of US and EU Systems Ken Alexander, Federal Aviation Administration Ignacio Fernández Hernández, European Commission This briefing, presented during Working Group A (Compatibility and Interoperability), summarizes joint U.S.-European studies documenting the combined performances of GPS-Galileo and WAAS-EGNOS.
DOWNLOAD 200 KB	Link Budgets John Betz, contractor to U.S. Air Force This briefing, presented during Working Group A, discusses the need for GNSS providers to avoid interference with each other by consistently defining their maximum received signal power levels.
Coming Soon	Outreach Panel at ION GNSS 2011 Rick Hamilton, Coast Guard Navigation Center Tom Von Deak, NASA This briefing, presented during Working Group C (Information Dissemination and Capacity Building), describes efforts to organize a panel discussion about the ICG during the Institute of Navigation's GNSS 2011 conference.
DOWNLOAD 9 MB	Aviation Augmentations Status Update Leo Eldredge, Federal Aviation Administration This briefing, presented during Working Group B (Enhancement of Performance of GNSS Services), provides detailed updates on the FAA's aviation augmentation systems (WAAS, LAAS) and discusses the growing interference problem caused by small GPS jammers.
DOWNLOAD 540 KB	Geodetic Reference Systems Template Barbara Wiley, National Geospatial-Intelligence Agency This briefing, presented during Working Group D (Interaction with International Organizations, National, and Regional Authorities), proposes a standard format for GNSS providers to use in describing their respective geodetic reference systems.
DOWNLOAD 200 MB	GNSS Timescale Description Template Ed Powers, U.S. Naval Observatory Stephen Mitchell, U.S. Naval Observatory This briefing, presented during Working Group D, proposes a standard format for GNSS providers to use in describing their respective system timescales.
DOWNLOAD 600 KB	Applications of GPS Provided Time and Frequency Ed Powers, U.S. Naval Observatory This briefing, presented during a plenary session on timing, describes the precise time service provided by GPS and the variety of civilian applications it has enabled.
DOWNLOAD 106 KB	Introduction of the Interagency Operations Advisory Group (IOAG) James Miller, NASA This briefing, presented during a plenary session, describes the Interagency Operations Advisory Group, a forum for identifying common needs across multiple international agencies for coordinating space communications, policy, high-level procedures, technical interfaces, and other matters related to interoperability and space communications.
