The AP20 AutoPole – Revolutionising Total Station Measurements
The Leica AP20 AutoPole is truly a unique smart solution that solves many challenges that surveyors experience today when using a prism pole together with an automated total station. The AP20 is comprised of an intelligent sensor module which communicates with our automated total stations and MultiStations and can be attached onto our new AP Reflector Pole with passive sensing elements. Combined, it is possible to measure points with a tilted pole, automate pole height adjustments and search and lock onto any standard target which is mounted on top of the pole.
To support stakeout and survey tasks to the most extent, the AP20 is designed both for one- and two-person operation. It can be operated directly from the total station or from a field controller or tablet. For these reasons, the AP20 fits flexibly into your existing total station survey setup.
Three Powerful Possibilities for the Surveyor’s Workflow
Each of the AP20’s unique functionalities provides distinct and significant advantages to the surveyor’s workflow.
- Tilt compensation - Tilt compensation is a feature that enables point measurements with a tilted pole, eliminating the need to level the pole and hold it steady during point measurement. Essentially, the AP20, replaces the individual levelling uncertainty of the pole operator with the certainty of a reliable IMU sensor. Even when you must drastically tilt a pole to reach a point, you can be confident that the tip of the pole is always the point being measured. Tilt compensation makes points accessible that were previously too difficult to measure or even impossible to reach. At the same time, productivity increases because you can collect data or stakeout a location without slowing down to level the pole.
- PoleHeight - With PoleHeight, the AP20 automatically measures the current length of the pole and applies the detected changes in Leica Captivate field software, removing the need to read, check and enter height changes manually in the field software. This also eliminates time-consuming post-processing to fix incorrectly entered or forgotten target heights, saving time in the office as well as the field. Conditions on sites are rarely static or predictable, you might often need to change the length of the pole to ensure line of sight to the total station over obstacles. With the AP20’s PoleHeight functionality, you can easily adjust the height to accommodate the situation, with the assurance that the correct pole height is always recorded.
- TargetID - Today, our automated total stations and MultiStations are already able to detect what is, and what is not, a target and thereby can filter foreign reflections. Now with the AP20, they can detect if the target is your target. TargetID, enables the total station to uniquely identify your target during search, preventing lock onto other targets. This feature is particularly useful when several surveyors are working on a site together.
