Author : Michael Scharber Organization : Scripps Orbit and Permanent Array Center (SOPAC) Date : August 7, 2003 Description : These schema components were desgined to encapsulate and validate : GPS/GLONASS receiver equipment for use/reference in : other XML document types, such as IGS-style Site : Information Logs, and GPS/Geodetic Observation/Occupation Log : from the National Geodetic Survey (NGS). : : The data model used in this XSD aims at uniquely-identifying : a given (single) GPS/GLONASS receiver. This entity could then : be contained within a parent entity which attributes other : aspects of where, when, by whom, and why this particular piece : of equipment was used or referenced. : Notes : All distance/length measurements/values are assumed to be in meters. : All date/time measurements/values are assumed to be of the : ISO8601 variant "CCYY-MM-DDThh:mm:ssZ" (UTC) Pulling in schema components for generic geodetic equipment structures. Instantiable, non-substituble, global complex type representing a GNSS Receiver uniquely-identified by a serial number and IGS model code. Instantiable, non-substituble, global complex type representing the settings (transient properties) of a gnss receiver. Refers to a satellite constellation being observed by a gnss receiver. Refers to the manufacturer- designated version of the firmware installed on a gnss receiver. Refers to the elevation mask (or cutoff) used on a gnss receiver. Refers to the temperature stabilization on a gnss receiver. Refers to the sampling interval with which observations are made with respect to the observed constellation(s) of satellite(s). Refers to the sampling interval with which observations are made with respect to the observed constellation(s) of satellite(s).
