Difference Between RTK and Static Oklahoma GPS Survey

Sep 27, 2022 | GPS Survey

Civil engineering, land surveying, and land planning firms have integrated the Global Positioning System into their practices because Oklahoma GPS survey techniques allow technicians to accurately and efficiently calculate precise distances, heights, latitudes, and longitudes. Since its introduction into these industries, many variations of GPS surveying practices have been developed.

There are many different methods that technicians utilize when surveying, each of which requires specific equipment capabilities and involves unique parameters. Two of the most frequently conducted GPS survey Tulsa types are RTK and static. To determine which service will benefit your project the most, it helps to learn more about the differences between them.


Understanding Static and RTK Oklahoma GPS Surveys

RTK and Static surveys provide highly accurate information that can assist in the design, construction, and post-construction phases of significant projects. While these styles lead to similar results, each involves a unique process.


Static Tulsa Surveying

Surveying technicians utilize static positioning procedures to establish and define the baselines between stationary GPS units. Based on the needs of your project, the practice may involve a multiple baseline approach or several units. To ensure the overall accuracy of the results, the technician will observe the area over various sessions for an extended observation time and note any redundancies.

Depending on the data that your project requires, the technician may conduct a Fast-Static survey. While these procedures also establish the baselines between units, this style involves a shorter observation period. To gather results efficiently, the technician will utilize advanced equipment with a radial baseline technique, network technique, or a combination of both.


RTK Tulsa Surveying

Real-Time Kinematic surveys are a specialized version of the Kinematic GPS survey. During a traditional Kinematic survey, a technician will use both portable and stationary units to get the data a specific project requires. For the survey, at least one stationary unit is set at a pre-established location. After this, one or more portable units are relocated from station to station. Kinematic surveys may be continuous or “stop and go.”

As an advancement on the traditional style of Kinematic GPS surveys, RTK surveys provide real-time results. For this procedure, the technician will measure the relative positions of specific points by utilizing two Global Navigation Satellite System (GNSS) antennas. This technology is especially useful as it can provide centimeter-level accuracy in a very short period of time.
