Hidden Point

Introduction

This manual describes the "HIDDEN POINT" program of the TPS SYSTEM 1000 instruments.

The program allows measurements to a point that is not directly visible using a special hidden-point rod. The data for the hidden point are calculated from measurements to the prisms mounted on the pole with a known spacing and a known length of pole. The pole still may be kept slope.

"Measurements" are calculated as if the hidden point was observed directly. These "calculated measurements" can also be recorded.

The hidden-point rod can have either two or three reflectors. The rod you are using is defined in the "CONFIGURATION" of the program. Here, you enter the length of the rod, spacing between reflectors, and the prism constant. Refer to Figure on page 112, which illustrates a hidden-point rod with three reflectors.

HP

If the hidden-point rod you are using has three reflectors, the program calculates coordinates for the hidden point from three combinations:

Reflector 1 + Reflector 2

Reflector 3 + Reflector 2

Reflector 1 + Reflector 3

In the case of motorized theodolites, you can configure the program in such a way, that it points the telescope at the third reflector automatically after the first two reflectors have been measured.
