How can I use your equipment to establish ground control points for an aerial site surveys to achieve accurate northing/easting/elevation coordinates in AutoCAD Civil 3D? Do I need setup my base station then go to my GCP's and mark then go to the next GCP and so on? Do I need an internet connection to gather the data?  A base must be set up in the original point, and the RTK corrections must be transmitted to the rover. After that, the cm-level position of the rover will be available. You can place the rover in the 10-12 GCPs, respectively and get their accurate positions. After that, the northing/easting/elevation can be calculated. No internet access is needed to get the accurate positions of the rover. The corrections can be transmitted from the base to the rover via a radio, which is included in our kit . Contact us: info@tersus-gnss.com Website: www.tersus-gnss.com

Can Precis-BX306 work well for aerial photogrammetry with UAV without the need for ground control points (GCPs) ? Yes, the following solution can be used to replace the GCPs: You can setup a base with our Precis-BX306 , and then transmit RTK corrections from the base. After the corrections are received, it will output accurate (cm-level) positioning and heading info. In the application of aerial photogrammetry with UAV, after the camera take a picture, it will send a pulse from the PC (Prontor-Compur connection) port to the receiver, the accurate position (cm-level) will be saved. The photos and their positions will be input to the mapping software (eg, PIX4D or Agsoft) to get an accurate map. Do I need a specific camera to work or any camera? No specific camera is needed; you can use any camera which has a PC (Prontor-Compur connection) port. And the synchronization between the shutters to the flash must be enabled. When the camera is taking a photo...
