RTK Data Collection

Once your horizontal and vertical projections are solved, you are

ready to collect data. The different measure mode settings and data

collection options are described below.

Measure Mode

1. From the Data Collection screen or from any GPS stake out

screen, tap Settings to open the Job

> Settings > Measure Mode

card.

2. Select the receiver dynamics.

• Static on occupy will set the receiver to ‘static’ mode for point

occupations. When in static mode, the receiver assumes no

antenna movement and uses advanced averaging techniques

to compute the most precise position possible.

• Dynamic always will leave the receiver in ‘dynamic’ mode for

point occupations.

3. Select the Accept filter.

• Fixed RTK only will reject all positions that are not fixed.

Code, Float, or Fix will allow you to accept any position except

autonomous or invalid data.

Note: If you are collecting simultaneous RTK and post processing

data, you can accept an autonomous position based on the

Job/Settings, Post Process card. If enabled, you will either be

prompted to put the autonomous position on a separate layer, or it

will automatically be stored on a separate layer.

4. Set the Acceptance Criteria.

• Acceptance Criteria is used to check each solution you accept.

If the measurement exceeds the criteria, you will be prompted

to accept or reject the point. Check this box if you want to

enable criteria checking. Enter a maximum value for HRMS,

VRMS, and/or PDOP in the fields. Only fields with a non-zero

value will be used for criteria checking.
