Kinematic Data Collection using Topcon TopSURV

Starting The “Base” Occupation

Requirements:

1. A serial or Bluetooth connection has been established between the FC-200 and the GR-3 Base.

2. The SD memory is installed in the GR-3.

Performing a Static Survey

1. To open the Start Base screen choose the GR-3 Kinematic configuration in the Survey Config screen (use the Configure icon) and tap clip_image005Setup GPS > clip_image007 Start Base.

2. Enter the parameters of the occupation point: name, code and antenna height and height type.

3. Tap Start Base. The survey will start, and the Duration field displays the timeclip_image002 passed, since the beginning of survey.

4. To stop the survey, tap the same button (when taped, it changes (toggles) to Stop Base).

Kinematic Data Collection on the “Rover”

Requirements:

1. A serial or Bluetooth connection has been established between the FC-200 and the GR-3 Rover.

2. The SD memory is installed in the GR-3.

Performing Data Collection

1. To open the Topo screen select Survey>clip_image009 Topoclip_image011

2. The Topo screen will look very similar to the Topo screen when surveying in RTK mode. clip_image014

3. With the static configuration we will start a log file first. When starting a log you will give this a name for the area or job if you are going to run a kinematic survey.

4. After starting the log tap the Starclip_image016t button to begin the epoch count for that observation. The observation for that point will continue until the desired epoch count has been reached. This is the Stop portion of the Kinematic observation.

5. If you are collecting in Kinemclip_image019atic Mode you will leave the log file running and move to your next point. This is the Go part of the kinematic survey.

TopSURV Kinematic Configurations

The following example configuration will allow Kinematic Data Collection using Topcon TopSURV data collection software:  

image image Add a new configuration called GR-3 Kinematic (This configuration is of course intended for a GR-3 receiver)

image image Set the logging rate to the desired rate. This should be equal too or less than the rate on the Base station. The Logging Rate also dictates the epoch count.

Selecting User Defined as the File Name allows you to name your static/kinematic files instead of the default Topcon timestamp.

Occupation time is simply a suggested occupation time based on the number of Satellite Vehicles and the antennas  frequency capability. The Number of ephocs dictates the length of each observations. If the logging rate is set at 5.0 and the Number of Epochs is set at 12 then the total occupation time would be: 5X12=60 seconds.
