Go to the Job > Settings > Post Process screen. Set a Recording Interval in the drop down list if you wish to record raw GPS data in the receiver’s internal memory for post processing in the office. Set the Recording Interval to OFF if you do not want to log post processing data simultaneous with the RTK survey.
6 already, and upload this file to the data collector. Open this file, or open a new job and import this file into the new job as control. • You will be prompted to set the last used mapping plane zone when you start a new job if you have previously selected a zone. • You can open a new job and then select the correct zone before you start the survey. To select a map projection zone: 9. Go to the Survey > Projection screen and tap Switch to Mapping Plane …. 1.
Survey Pro Basic GPS Quick Start Guide 7 an internet GPS service with a cell phone for a modem, or if you are using a rover with a radio and the base is already setup and broadcasting corrections, follow the steps in the Remote Rover section. Start Base Receiver 1. Go to the Survey > Start GPS Survey screen. If you are using a serial cable for base and rover, connect the base serial cable to the data collector.
8 the instructions below to select the proper base point for your first GPS base. Select Base Point 5. The user interface shown on the Select Base Point page will depend on the location of the base setup and whether or not any GPS points or a GPS coordinate system exists yet in the job. Before showing the Select Base Point screen, Survey Pro will search the job for a point that matches the location of the base.
Survey Pro Basic GPS Quick Start Guide 9 Start Rover Receiver 7. On the Rover Setup page, review the antenna Measured height and Measure To mark. 8. When the rover receiver has received and verified the base position, a button will appear on the bottom right hand side of the interface. This button will be labeled either Finish or Next >, depending on the need to solve a localization after GPS receiver setup.
10 automatically attempt to connect to a rover receiver using the method selected for the rover’s connection setting, either serial or Bluetooth. If you are using a radio link for base corrections, and you are using a serial cable for both base and rover, connect the cable to the rover to start the connection. If you are using a radio link, and you are using Bluetooth for either base or rover, tap Rover when prompted for the receiver to connect to. 2.
Survey Pro Basic GPS Quick Start Guide • • 11 button for either new or known point, and enter the Base Point name in the edit field. When Survey Pro finds a unique point in the job file that matches the base location, the Select Base Point page shows you the name of the base point found. When Survey Pro finds more than one point in the job file that matches the base location, the Select Base Point page has a drop down list of possible matches for you to choose from.
12 When using GPS, establishing the local coordinate of the base and orienting the setup is called localization. When you setup on a known point, the Survey Pro Basic GPS workflow is called GPS Backsight, and you need to collect one additional GPS control point with the rover to orient the setup.

Select an existing job file point, and check the boxes to set if you want to Use This GPS Control Point For: horizontal, vertical, or horizontal and vertical control. 3. Level the pole over the point and tap Start Control Point Occupy… to begin an occupation on the selected point and open up the Occupy Control screen. 4. When you are satisfied with the GPS observation, tap Accept to create the GPS control point and go back to the Localization Status page. 5.
14 9. Level the pole over the point and tap Start Check Point Occupy … to begin an occupation on the selected point and open up the Occupy Control Check Point screen. 10. Examine the calculated errors, and when you are satisfied with the observation tap Accept to create the GPS control point and return to the Localization Check page. 11.
Survey Pro Basic GPS Quick Start Guide • • • • • 15 If the localization solved and no blunders were detected, you will see a green light and the status line will show the root mean squared (RMS) error of the horizontal and vertical solution. If the localization solved and no blunders were detected, but some of the points used have a large residual error, you will see a yellow triangle and the status line will show the point with the largest horizontal and/or vertical residual.
16 Data Collection Screen There are different methods to collect data: Point : Use this function to take the most precise measurement to a point. Depending on your settings, this function will put the receiver into static mode, mark the event in the post processing logging file, and open the Occupy Data Points screen where you can remain in static mode for the desired length of time and store the point. Topo SS : Use this function to quickly store a point with slightly less precision.
Survey Pro Basic GPS Quick Start Guide 17 Traverse Base This function is used to move the base receiver to a new location and restart the RTK survey. When you tap Traverse Base , you will see the Traverse Base prompt screen. Traverse Base > : Use this function if you have already collected the new base point with the RTK rover, or if the point exists in the job file from other source. Follow the prompts to move the base receiver and restart the RTK survey from the new base location.
18 ¾ If you want to automatically store points that meet your criteria after five epochs of data collection, check the Automatically accept data collection points box. Stake Out This section describes: ¾ How to use the RTK rover in roving mode to navigate to a stakeout design location. ¾ How to switch the RTK rover to occupy a stake out design location or an as staked point. Stake out with GPS is very similar to stake out with conventional instruments.
Survey Pro Basic GPS Quick Start Guide 19 ¾ How to perform stop and go data collection with the EPOCH25 rover. ¾ What to do with the receiver’s data files after the survey. Data collection for post processing involves storing GPS raw data to a file on the receiver’s internal memory. Raw data from multiple receivers is combined on the PC and then software is used to process the base line measurements.
20 Note: The Post Processing screen will first check if the connected receiver is the RTK base or rover. If you are connected to the RTK base or rover receiver, your only option here is to stop recording. To start recording with the base or rover receiver, use RTK setup described in the previous section. If the connected receiver is already recording data, you can tap Stop Recording to end logging and close the file.
