Excerpt: ...then, if a meridian mark is used (which is not absolutely necessary), the transit should be set up in the meridian by the main telescope and the pointing on the sun or star may be made with the auxiliary telescope with or without the prism, as conditions may require. In observing transits the auxiliary telescope should be mounted on top and ranged into line with the vertical wire of the main telescope by using the two opposing screws as explained. In making solar and stellar observations with the main telescope and prism attachment, the telescope should always be reversed through the standards with the objective down instead of up. Cross Section Showing Our Edge-bar Needle and Compass-Likewise the watertight needle lifter combined with the toothed variation ring and pinion motion for instantaneously changing the graduation to any declination East or West. The needle shown in the cross section of our Transit compass also in the top view on opposite page, represents the form adopted and preferred by us for all of our compass instruments, because it has its greatest dimensions in the vertical direction; hence its name. At the ends, where it is read, it is quite thin, but increases in thickness symmetrically towards the central part to give it the rigidity necessary to retain the true longitudinal shape and yet be very light of weight to minimize the dulling of the pivot on which it swings. The point of suspension in the steel cap and the two ends of the needle are in a straight line, thereby forming the geometric axis. The advantage derived from the edge-bar form, therefore, is that its magnetic axis must be contained in the geometric axis of the needle, whence it follows that there is no index error at its reading ends. This cannot be...

Available in PDF, EPUB and Kindle. Book excerpt: With the advent of GPS/GNSS satellite navigation systems and Unmanned Aerial Systems (UAS) surveying profession is nowadays facing its transformative stage. Written by a team of surveying experts, Surveyor’s Instruments and Technology gives surveying students and practitioners profound understanding of how surveying instruments are designed and operating based on surveying instrument functionality. The book includes the required basic knowledge of accurate measurements of distances and angles from theoretical principles to advanced optical, mechanical, electronic and software components for comparative analysis. Readers are presented with basic elements of UAS systems, practical interpretation techniques, sensor components, and operating platforms. Appropriate for surveying courses at all levels, this guide helps students and practitioners alike to understand what is behind the buttons of surveying instruments of all kinds when considering practical project implementations.

Excerpt: ...horizontal wire coincides with the mark and then clamp the side-telescope to its hub. The telescopes are now set to correspond with thg zero of the vertical circle. To place the telescopes at an angle with each other. Level up and fix a mark when the main telescope is level. Then raise or depress the main telescope the required angle and clamp the horizontal axis. Now move the side-telescope until its horizontal wire bisects the mark and clamp it firmly to its hub. During an extended operation with the side-telescope, the relative position of the two telescopes should be verified from time to time to detect any disturbance of the side-telescope. Tm_nsits having the telescope mounted at the end of the horizontal axis of revolution are sometimes used in mines; or, as shown in the Alt.-Azimuths Nos. 15a and 15b, this construction is used in some instruments for geodetic and smaller astronomical work. The adjustment of such a telescope for collimation may therefore be explained in this connection. The following method is as simple as any: --. Select a well-defined object, as a church-spire, distant at least 5 or 6 miles. The..1strument being leveled, bisect the object with the vertical wire and read the verniers of the horizontal limb. Then turn the vernier plate so as to read exactly 180 different from the previous reading, and revolve the telescope. If the vertical wire is adjusted for collimation it will again bisect the distant object, since the space covered by the cross-wires on an object at such a distance will be much greater than the change in the position of the telescope as caused by its excentricity from the center of the instrument. If it does not again bisect the object, correct one-half the error by means of the hon zontal..
