This H-RTK module uses a helical antenna that offers significantly better precision compared to the standard lite M8P antenna.  This makes it possible to use this module as either a rover or base station module in your RTK setup. The enclosure is made from aluminum alloy and features an integrated safety switch and a tri-colored LED indicator, and it is compatible with the open source Pixhawk series flight controller.
