survey-grade GPS

Survey-grade GPS refers to high-precision positioning technology used mainly by professionals for mapping and surveying. Unlike typical GPS devices that provide approximate location within a few meters, survey-grade GPS offers accuracy within a few centimeters. It achieves this through advanced signals, multi-frequency receivers, and correction methods that compensate for atmospheric and environmental errors. This precision is essential for tasks like land boundary delineation, construction planning, and engineering projects, ensuring reliable and exact location data for critical applications.
