Course abstract

In the study course, students get acquainted with the development of the substantiation of the state geodetic network, its creation and maintenance processes. Students learn to perform accurate measurements of angles, distances and GNSS required for the formation of a geodetic network. Strengthens skills to work carefully and accurately both independently and in a group. To draw up measurement documentation in accordance with the requirements. Acquires to independently obtain, select and analyze information that is necessary for the performance of tasks in production work - using it, to make useful decisions and solve problems. Practices to detect possible measurement errors in a timely manner, to analyze the causes of their occurrence and to find ways to eliminate them. Be able to critically evaluate their knowledge and skills, be able to be responsible for the quality of their work.

Learning outcomes and their assessment

1. Knows the information collection processes about the existing geodetic network, can select and systematize. Can inspect geodetic points, assess the condition. Can install a new geodetic sign. Operations in training practice.
2. Knows the principles of testing geodetic instruments, can perform tests, and evaluate the application of a geodetic instrument, taking into account its accuracy indicators; Operations in training practice.
3. Can independently perform accurate geodetic measurements in field conditions, using angular, elevation, distance, and GNSS methods; Operations in training practice.
4. Has the skills to perform the mathematical processing of the obtained field measurements - smoothing, to evaluate the accuracy of the obtained results; Operations in training practice.
5. Can compile and draw up a report on the performed geodetic activities. Defence of practice.

Course Content(Calendar)

Full-time studies:
1. Expansion of the geodetic network. Survey of geodetic points, evaluation. Installation of a new geodetic point. Precision direction measurements, centering and reduction, trilateration edge length measurements;
2. GNSS measurements, polygonometric measurements, trigonometric leveling, precision leveling, geodetic measurements of direct intersections and other methods, chamber data processing, accuracy assessment. Preparation of the final report.
Defense of practice.

Part-time studies:

All topics specified for full-time studies are implemented, but the number of contact hours is 1/2 of the specified number of hours

Requirements for awarding credit points

Defense of study practice:
Composition of the defense of the study practice -
- Test of practical skills for working with geodetic instruments;
- Students present the logical course of study practice, discussions about the obtained results

Description of the organization and tasks of students’ independent work

- Training practice students fulfill the group's top goal practice tasks by the program, and prepares the report documents of the practice;
- After preparation of the practice report and submission to the practice supervisor, the practice group passes the final examination.

Criteria for Evaluating Learning Outcomes

- Training practice assessment will depend on the practical skills test results and practical running of the results obtained and the evaluation of the presentation.
- Must have fulfilled all the training practice tasks.
