This application can communicate with a layout navigator LN Series. By using this, you can perform the layout work of 3 dimensional design data and as-build measurement of 3 dimensional point data. Layout navigator LN Series is pursuing the increase in efficiency of survey work and the ease of using compared with the conventional survey instrument. The update rate of data has realized 20 Hz. So the data delay to the motion of the prism is minimized and the response of guidance to a layout point becomes smooth. Moreover, it can be re-tracked quickly when it failed of tracking the prism. By carrying the self leveling, LN Series can also be used easily by user which is not used to handling of a survey instrument. Main Features of layout navigator LN Series: +Realization of simplification of operation by the limit to the function of layout work and as-build measurement. +Realization of the laborsaving by the measurement by oneself. +Realization of improvement of operational efficiency by the optimal sequence for each of layout work and as-build measurement. +Realization of simplification of instrument setup by the self leveling and visual information of operation steps. https://www.topconpositioning.asia/jp/en/products/brand/topcon/ln-150/ To use this application, the use of location information should be enabled.
