Precision is the reproducibility of the measurement.It can be from + / – 10mm to + / – 2mm per kilometre.ġ0-12 kmNIKONOne second+ / – 2mm/km or 2ppmTriple the number of prisms double the distance.LEICAOne second SOKKIAOne second. Accuracy of a Total Station:Īccuracy depending upon the instrument and varies from instrument to instrumentġ.The angular accuracy varies from1″ to 20 ″.Ģ.Distance accuracy depends upon two factors.ī) Error due to the length of measurement. A fully charged battery works for about 3 to 5 hrs continuously.įigure 1: Different Parts of Total Station 1.3. It also consists of battery socket which houses the battery. It also has a memory card to store the data. It consists of an EDM, Theodolite, Microprocessor combined into one. ii) An angle measuring instrument (Theodolite). A combination of all the three results in a powerful instrument called TOTAL STATION.Hence, the TOTAL STATION is an instrument which consists of the following: Once distance and angular measurement is over computation is performed to provide the control points.Angle can be measured by using a THEODOLITE.Electronic Distance Measurement Instruments, Total station and GPS.Again, distance can be measured by using various instruments like chain, tape.Whatever the method the provision of control points, includes the measurement of two entities( Distance and Angle).There are several numbers of methods like traverse, triangulation etc., to provide these control points.The purpose of any survey is to prepare maps, control points formed a basic requirement for the preparation of these maps.
COORDS CHANNEL MOD PLUS
The total station is an electronic theodolite (transit) integrated with an electronic distance meter (EDM), plus internal data storage and/or external data collector. It is also used by archaeologists to record excavations as well as by police, crime scene investigators, private accident Reconstructionists and insurance companies to take measurements of scenes.
COORDS CHANNEL MOD SOFTWARE
Data can be downloaded from the total station to a computer and application software used to compute results and generate a map of the surveyed area.Angles and distances are measured from the total station to points under survey, and the coordinates (X, Y, and Z or northing, easting and elevation) of surveyed points relative to the total station position are calculated using trigonometry and triangulation.The basic properties are unsurpassed range, speed and accuracy of measurements. Total stations are developed in view of the maximal convenience of work of the user. High-efficiency electronic tachometers are intended for the decision It has the broad audience for sole of industrial problems.The measurement results can be recorded into the internal memory and transferred to a personal computer interface. The Total station is designed for measuring of slant distances, horizontal and vertical angles and elevations in topographic and geodetic works, tachometric surveys, as well as for solution of application geodetic tasks.
