200 Series MiniPod, Submersible GNSS

Model

201G MiniPod

The 201G MiniPod is a lightweight, ruggedised Tri-band GNSS receiver with configuration options. These allow for a RTK base, RTK rover and RTK moving base solutions to be used with more than one MiniPod in operation. Additional external sensor information can be added to the wireless protocol.

This enables the MiniPod to record precise GNSS positioning data remotely, including accurate dual axis inclination, temperature sensors, and information received from other data measurement devices. All 201G models are submersible to 50m water depth.
