I’m working on an outdoor, autonomous mobile robot project and wanted to ask a few questions regarding your GPS-RTK modules. I wanted to know if you can recommend any modules that would provide centimeter or millimeter level accuracy outdoors that can be integrated with the mobile robot? I also wanted to ask if an antenna is required for those modules? If so, does the antenna need to be placed on top of the mobile robot, or can it be placed inside the body of the mobile robot? Thank you
Yes, you need a multi-band GNSS antenna, outside, with a clear view of the sky, ideally horizon to horizon.
