DDC TC Values The TC value used with DDC solutions specifies the period of time over which DDC solutions should be used in calculating filtered DDC solutions Large TC values result in higher precision but slower filter response time and vice versa See Section 8 8 Effect of TC Value for an illustration of the impact of TC values To maximize the amount of information that can be obtained from the GPS data mmVu LabTime can calculate 3 simultaneous DD low pass filter solutions This provides the user with different resolution vs time options The default TC values are Table 8 Default DDC TC values 0 2 hr O hr for fast but less precise displacement detection 1 hrs 1 for moderate speed and precision TC3 6 hrs 1 for slow but most precise displacement detection This option is available for the users who have an RTK license The number of filters used will dictate the amount of output data that is generated and the amount of time required for processing For large scale applications it may be necessary to be selective in which TC values are employed To disable any particular TC value enter a value of 1 If one or more TDD Q values or DDC TC values gets assigned a new value a particular filter or more filters get reinitialized Engine Status Select Keep TDD DDC status to keep the filter status Select Reset the TDD DDC status to reset the filter status If you select Reset the TDD DDC status the
