GPS survey Tulsa technology has had a significant impact on the Tulsa surveying industry. Any land survey involves gathering data about the positions of specific points to determine the distances and angles between them.

1. What Are the Four Types of GPS Survey Tulsa Techniques
GPS survey Tulsa technology has had a significant impact on the Tulsa surveying industry.
Any land survey involves gathering data about the positions of specific points to determine the
distances and angles between them. Oklahoma GPS survey technology allows those
measurements to be made more quickly and accurately than ever.
Understanding Oklahoma GPS Survey Technology
GPS technology utilizes a sophisticated satellite network that communicates with ground-based
receivers. When calculating locations, these satellites are highly specific, allowing the technician
to record each receiver’s exact height, latitude, and longitude. Additionally, GPS technology
provides data on the velocity, speed, and time synchronization of moving receivers.
The 4 GPS Survey Tulsa Techniques
Static
These procedures establish baselines between stationary GPS units. To do this, the receivers
record data over an extended period, during which the satellite geometry changes. Static
positioning often involves a network or multiple baseline approach; for this, the technician will
utilize multiple receivers, baselines, observational redundancies, and sessions. By using very
long observation times, the technician can guarantee a high level of accuracy.
Fast-Static
These procedures are similar to static surveys; however, they have a shorter observation period.
As such, fast-static surveys require more advanced equipment and methods. These procedures
are used when horizontal accuracy is very important. By utilizing a radial baseline technique,
network technique, or combination of both, this method can get results in a comparatively shorter
observation time.
Kinematic
For these procedures, at least two GPS units are utilized. At least one unit is set up over a pre-
established station, where it remains fully stationary. The other units move from station to station.
Kinematic surveys can be continuous or “stop and go” (which have a duration of two minutes or
less). Real-time kinematic (or RTK) is a versatile and highly precise technique that allows for
useful real-time results.

2. OPUS
These procedures involve the National Geodetic Survey’s Online Positioning User Service
(OPUS). For this, users submit individual GPS unit data files to OPUS, where it automatically
processes them. While these procedures will not produce final coordinates, they can be used to
verify other procedures. OPUS provides free access to highly accurate coordinates from the
National Spatial Reference System (NSRS). Of course, there are regulations in place to ensure
that all of the submitted data is reliable and accurate.
Using Tulsa Surveying Data
The data found through GPS technology can be utilized in many ways. The five primary uses of
GPS technology include:
 Location; to determine a point’s exact location.
 Navigation; to guide individuals when moving across locations.
 Tracking; to monitor a person’s or object’s movement.
 Mapping; to create a plan or map of an area.
 Timing; to make precise time-based measurements.
While there are many benefits of utilizing GPS technology, one of the most prominent is that a
high-quality GPS land survey can help any project succeed.
