Trigonometric leveling is a technique used in land surveying applications to determine elevation differences between two points using angular measurements and distances. Unlike geometric leveling, which determines elevation differences from staff readings, trigonometric leveling uses trigonometry to indirectly calculate the height difference.

To compare the determination of height differences using GNSS and total station, a 5 km itinerary is carried out, consisting of 11 materialized points spaced every 500 m, producing a total of 10 height differences, which are observed directly using GNSS and total station.

The Trimble S5 can be operated from a wide range of controllers. Among them, a good alternative is the TDC600, which can be used in different modes and is compatible with Trimble's entire S-series of total stations as well as its GNSS portfolio, or both simultaneously.

It is strictly necessary to configure a map projection when working with a total station, and even more so when combined with determinations made with GNSS. This applies to any map projection, even those that minimize the effect of the combined scale factor on projected distances.

If you are looking to automate precise total station observations for monitoring projects, we recommend the Trimble S9 HP + Trimble 4D Control (T4D) solution.
