Even if the accuracy of the base station is 1.5 to 2 m, the position accuracy of the rover module relative to the base station can still reach centimeter level.Īfter the survey is complete, Mission Planner will display the following page: If your application does not require UAV with high absolute geographic accuracy, you do not need to set the base station’s precision too high, resulting in long survey time. It should be noted that the absolute geographic accuracy of the base station here will affect the absolute geographic accuracy of the rover module without affecting the relative accuracy between the base station and rover. Testing shows that, in an open area without shelter, to achieve the absolute accuracy of 2m takes a few minutes to reach the absolute accuracy of less than 30cm takes around an hour to reach the accuracy of 10cm takes a few hours. The base station needs a certain amount of time to meet the accuracy requirements of your input. The green bar at the lower part of the Mission Planner page shows the satellites being detected and the signal strength related to each satellite. You will see the following page:ĭuring the survey process, the right box will show the current survey status: Position is invalid: base station has not yet reached a valid location In Progress: survey is still in progress Duration: The number of seconds that the current surveying task has been executed Observation: the number of observations acquired Current Acc: Absolute geographic accuracy that the current base station can achieve. Click on Restart, the ground station will transfer the data you have entered to the HERE + base module, the base module will start a new round of surveying.
In the Time column, enter the minimum survey time you expect. In the SurveyIn Acc section, enter the absolute geographic accuracy that you expect your HERE + base station to achieve. Select the correct base module com port in the top left corner and click connect.
Open the Mission Planner ground station software on your computer and go to the initial setup -> Optional Hardware -> RTK / GPS Inject page. During the base station setup, the rover and the UAV do not need to be turned on.
If the uploading is successful, the upgrade interface is displayed in green if the upgrade is aborted, the interface is displayed in red. Uploading usually takes only a minute or less.
