Trimble PX-1 RTX

The Trimble PX-1 RTX is a relatively expensive but also highly accurate RTX GNSS+INS. It supports corrections from a satellite or cellular network through CenterPoint® RTX Correction service. RTX provides centimeter accuracy without the use of a base station. Although the PX-1 is designed to be used as an external inertial navigation system, it is also supported for use as a strict GPS in ArduPilot. Detailed information from the manufacturer can be found here.
