3.3.6. Smart Stations

Site surveying is increasingly being carried out using GNNS and Total Station equipment.

Smart Stations are advanced tools used in site surveying to improve efficiency. They are a combination of two technologies: GNSS (Global Navigation Satellite System) and Total Stations. Site surveying, which involves measuring and mapping land, has traditionally depended on these instruments. The integration of these technologies into Smart Stations makes the process quicker and more efficient.

Think of Smart Stations like smartphones combining the functionality of a camera, GPS, and computer into one device, making it easier and faster to complete various tasks.

Integrated survey rovers (called Smart Stations) combine the GNSS and Total Station to significantly improve the efficiency of survey work. It ensures that in case of obstruction in horizontal visibility, GNSS antenna is connected to the Total Station, and all operations of GNSS observations are performed through the keyboard of the Total Station.

Smart Stations combine the best features of GNSS and Total Stations to enhance surveying. If there is an obstruction (like a building or tree) that blocks the satellite signal, the GNSS antenna can link up with the Total Station. This means that surveyors can continue their work without interruption by using the Total Station to conduct GNSS observations, effectively merging the strengths of both technologies.

Imagine trying to drive in a busy city. If GPS signals get blocked by tall buildings, a navigation app on your phone can still use road data to guide you, similar to how Smart Stations switch to other methods when GNSS signals are obstructed.

Where GNSS does not receive good signals from the satellites due to vertical obstructions, Total Station is used.

When GNSS signals are weak or obstructed (like under a bridge or dense vegetation), the Total Station becomes the primary tool for surveying. Total Stations measure angles and distances with high precision, allowing surveyors to obtain accurate data on site even when satellite signals fail.

It's like being at a concert where it's hard to see the stage due to other people standing in the way. Instead of giving up on the concert, you could rely on your friend, who has a better view, to tell you what’s happening.

These latest developments in Total Stations are also capable to provide data for building information modeling (BIM) and virtual design and construction.

Recent advancements in Total Station technology have expanded their use beyond traditional surveying. Now, they can provide data that's integrated into Building Information Modeling (BIM) and virtual design processes. This means that the data collected from surveys can be directly used in creating detailed models of buildings and infrastructures, improving planning and design efficiency.

Think of it like a designer using a 3D printer to create models from digital designs. The transition from surveying to creating detailed models helps teams visualize the project before it is built, leading to better outcomes.

Although the use of GNSS is increasing, but the Total Stations are one of the predominant instruments used on site for surveying, and will be used in future along with other surveying equipment to provide accurate and faster data collection approaches.

Despite the growth in GNSS technology, Total Stations remain crucial in field surveying. They will continue to be used alongside GNSS for effective data collection on-site. The combination of these tools promises more accuracy and speed, which are vital in construction and planning.

Just like a Swiss Army knife, which combines multiple tools for different tasks, the combined use of Smart Stations and Total Stations provides surveyors with more tools to handle diverse challenges in the field.

Developments in both technologies (GNSS and Total Station) will find a point where devices can be made that complement both the methods.

Looking ahead, the continuous advancements in GNSS and Total Station technologies will lead to devices that can utilize both systems efficiently. This synergy will enhance survey accuracy, reducing reliance on a single technology and increasing robustness in various conditions.

Consider how smartphones incorporate cameras, GPS, and internet access all in one device. Future surveying tools will likely merge GNSS and Total Station capabilities for comprehensive data collection.
