In this post, I'll walk you through setting up the RoboDot as a GPS base station using online services, a crucial step for achieving high-precision mapping and surveying results. This is just one of three methods to establish the RoboDot at an absolute point, ensuring your work can be referenced by other surveyors or projects in the future.
Three Methods for Setting the RoboDot to an Absolute Point
Manual Setup: This method involves entering the coordinates directly into the RoboDot. It’s the simplest approach but requires a known point on site.
OPUS Online Processing: The OPUS (Online Positioning User Service) provides accurate location correction by processing static observation data. This method is highly recommended for achieving the best possible precision. You can submit your data to OPUS, which will return corrected coordinates for your base station.
Internet Base Station: With this method, you connect the RoboDot to another base station online. This allows for dynamic updates and is particularly useful when working in areas without an established GNSS network.
The Benefits of an Absolute GNSS Base Station
Setting up a GNSS base station on an absolute point has several advantages. It allows other surveyors and projects to use your reference point, which enhances collaboration and ensures consistency across different mapping efforts. This setup is especially beneficial for projects that span large areas or involve multiple teams.
Reliable Mapping with RoboDot
Once your RoboDot is configured as a base station, you can confidently map with your drone, knowing that your connection remains stable even if the internet drops out. This reliability is crucial for extensive mapping projects where data integrity cannot be compromised.
Improved Relative Positioning and Shorter Baselines
Using the RoboDot as your base station enhances relative positioning between images, resulting in more accurate maps. Shorter baselines—meaning the distance between the base station and the drone—are key to achieving this precision.
Virtual Reference Station (VRS) Service
Another great feature of the RoboDot is its integration with the VRS (Virtual Reference Station) service. After your RoboDot has completed using the VRS service, it becomes available for others in the area to use, further extending its utility and ensuring precise positioning for more users.
Dual Correction Source Capability
The RoboDot can serve as a correction source for both your drone and a RoboDot rover simultaneously. This dual capability is invaluable for projects that require real-time corrections for multiple devices, enabling high-precision positioning and reducing the need for additional equipment.
Conclusion
Setting up the RoboDot as a GPS base station using online services is straightforward and offers numerous benefits for mapping and surveying projects. Whether you're using manual entry, OPUS processing, or connecting to another internet base station, the RoboDot provides a robust and reliable solution.
