Base station-rover vs rover-rover setup for placing rtk gps
I am searching about the ways I can place rtk gps modules for outdoor localization. based on the _swiftnav_ documentation, there are two ways to do that:
Typically one module is a stationary base station, which may be located at a surveyed point, while the other is mounted on a rover and provides ROS navigation software with a highly accurate position relative to the base station....
Other configurations of two modules are possible, such as placing both on moving platforms. Each device computes its position relative to the other. This symmetry of operation enables the robot's position to be found using position data from either the base station or the rover.
What is the advantage (or disadvantage) of the second method over the first one?
How the second approach is useful as the modules output relative location?
Thank you in advance.
Some expectation management: I'm not sure you'll get answers to your questions here. This is a very specific product, and you're asking questions about how to (best) use/configure that product. You may want to try a different forum / support channel, as the intersection between users of that specific package+product and ROS Answers members will likely not be very large.
Hi gvdhoorn. Thanks for your comment. I understand you point, but I think my use case is not very specific. Almost any outdoor autonomous navigation setup needs some sort of gps.
