- SBPS stands for Space Based Positioning System.
- It is a fast and accurate method of determining the location of any point of interest anywhere on the face of the earth of any time during day or night.
- The technology collects and processes signals from satellites in orbit around the earth to determine the location of points of interest on the ground.
Segments of SBPS:
It consist of three segments:
- Space Segment(SS):It generate an transmit code, carrier phases and navigation messages.
- Control Segment(CS):It produces GPS time, predict ephemeris and manage space vehicle.
- User Segment(US):It gives navigation and surveying solution
Advantages of SBPS:
- It gives higher positional accuracies, even in the order of subcentimeter.
- Angular and linear measurements are not required to find position of points.
- There is rapid speed of work.
- It is independent of plumb line which is a reference direction for almost all types of survey systems.
- It does not require line of sight.
- Pre-established reference points are not required to establish the points with same reference coordinate system.
- Digital output, computer compatible ,easy to adjust, process and plot.
Application of SBPS:
- Determine the boarders, making existing utilities like highway, municipal amenities photogrammetric and private site specific projects make them more dense or compact.
- GIS data acquisition.
- Establishing state plane coordinates or geodetic coordinates.
- Used in As-built survey and Topographic survey.
- One uses it for mine exploration.
- Used in Baseline survey and transverse control survey or transverse verification surveys.
- One uses it in natural resource mapping.
- Used in communication tower survey and certifications.
- Used in construction stakes out utilities, highways, facilities, pilling etc.
