This interface control document defines the (e)Loran based alternate PNT interface for the EGI. It provides technical descriptions of definitions, specifications, and explanations for general distribution to providers, manufacturers, and consumers.

This standard provides guidelines for resilient GNSS receivers.

This standard defines how a resilient GNSS receiver provides enough information for an alternative PNT source to be selected when the GNSS receiver does not meet the required levels of accuracy, availability, integrity, or continuity even when the GNSS signals are subject to interference

This recommended practice enables users to utilize raw GNSS measurements to improve positioning, navigation, and/or timing solutions.

This information report provides an overview of the eLoran PNT system.

This standard, SAE1002, is a republication of FGDC-STD-011-2001, and defines a preferred USNG for mapping applications at scales of approximately 1:1000000 and larger. It defines how to present Universal Transverse Mercator (UTM) coordinates at various levels of precision. It specifies the use of those coordinates with the grid system defined by the Military Grid Reference System (MGRS). Additionally, it addresses specific presentation issues such as grid spacing. Together, the UTM coordinate representation, the MGRS grid, and the specific grid presentation requirements define the USNG. Use of USNG grid coordinates may be useful, and even desirable, within some systems or enterprises. The decision to use USNG grid coordinates or some other coordinate system internal to geographic information systems or location service appliances is left to the discretion of the system developer as long as the human interface provides for USNG grid coordinate readout as one option.

This recommended practice provides users with raw GNSS measurements to facilitate positioning, navigation, or timing solutions.
