Learning outcomes of the course unit

Basic knowledge of students about theory of errors. Basic information of precision of measurements and adjustment.

Prerequisites

Surveying and computing of measurements on the plane, Linear algebra - fundaments of matrix calculus, Analytic geometry, Derivative of a function, Taylors expansion of a function.

Co-requisites

Basic knowledge of surveying methods, Precise measurements of distances and angles, Mathematics - partial derivative

Planned learning activities and teaching methods

The course is taught through lectures, practical classes and self-study assignments. Attendance at lectures is optional, but attendance at classes is compulsory.

Assesment methods and criteria linked to learning outcomes

Attendance, submission and acceptance of single tasks protocols, 4 test, passing the final written test. The exam is composed from test examples, exercise and oral part. 30% of the points are generated from the exercise evaluation. 20% from test examples and 50% oral part of exam. The total number of points is 100, for the successful completion of the exam 50% of points
