What is the purpose of the bilby tower?

The purpose of the bilby tower is primarily to allow for more accurate triangulation surveys. This type of survey uses the position of the tower as a fixed point from which surveyors can measure angles to various targets. By employing triangulation—the method of determining locations based on the angles between points—the bilby tower serves as a crucial reference elevation point, improving the accuracy and precision of the survey results. This method is particularly valuable in surveying applications, as it enables surveyors to establish control points over relatively large areas.

Additionally, the bilby tower can assist in enhancing surveying capabilities by providing a stable observational platform that minimizes errors associated with ground-level obstructions, variances in terrain, or other environmental factors that could compromise measurements taken directly from the ground.

Other options, while relevant in their respective contexts, do not align with the primary intended use of the bilby tower in the realm of triangulation and surveying accuracy.
