Webinar Description:

The use of GNSS technology has become common within the surveying profession. This is especially true when it comes to the use of real-time techniques (Real-Time Kinematic) and Real-Time Networks (RTN). These techniques offer methods that significantly increase productivity, with little degradation of accuracy. But a tool by itself does not produce accuracy or confidence. The procedures used, and attention to detail by the user, are what helps to ensure you achieve the results you are aiming for. In this webinar, we will discuss the GNSS tools and techniques that are available, their adequacy for common survey tasks, and take an in-depth look at “best practices” that have been developed by practitioners that are designed to catch blunders, eliminate common systematic errors, and increase confidence in survey results. We will also look at the newly released NGS Standards and Specifications, which include the use of Real-Time techniques, and provide research showing why certain specifications or techniques are required.

This presentation will reference NOAA Technical Memorandum NOS NGS 92.
