5-1.25B Definitions automated machine guidance: Technology that uses one or more positioning devices, such as GNSS, robotic total stations, or rotating laser levels, to determine line and grade, or control the real-time position of construction equipment using onboard computer equipment.

California Coordinate System of 1983 (CCS83): California Coordinate System as defined in Public Resource Code §8801.

Caltrans Spatial Reference Network: The Department owned and operated GNSS real-time positioning network. This network is used to collect data to be used for the design and construction of transportation improvement projects.

digital construction model: Electronic three-dimensional model of the project’s proposed design infrastructure used by the Contractor's AMG equipment.

digital design model: Electronic three-dimensional model consisting of roadway design elements including alignments, profiles, and cross sections representing the finished grade.

digital terrain model: Electronic three-dimensional model that represents the original ground before job site activities begin.

global navigation satellite system: Constellation of orbiting satellites used to determine the geographic location of a user's receiver on the surface of the earth.

GNSS base station: Single ground-based instrument consisting of a GNSS receiver, antenna, and telemetry equipment that provides GNSS corrections to other GNSS receivers. Base stations can be set up temporarily or permanently constructed. Multiple base stations can be combined into a GNSS real-time network.

GNSS correction service subscription: Subscription service to receive GNSS corrections for GNSS positioning through a private GNSS real-time network. Corrections are typically received via cellular wireless data services.

GNSS real-time network: Satellite-based correction service using a collection of ground-based receivers and a central processing center that provides highly accurate location services to users instantaneously over a broad geographic region.

GNSS rover: Portable GNSS antenna, receiver, rod, and data collector with telemetry equipment for real-time point measurements.

GNSS site calibration: Process that establishes the relationship between the observed control point coordinates and the established control point coordinates that define the project survey datum.
