NUT4NT+

Open, professional satellite navigation equipment.

This project is coming soon. Sign up to receive updates and be notified when this project launches.


NUT4NT+ is our multi-frequency, multi-signal, front-end receiver board built around the NT1065 chip. It’s a low-power, low-cost, all-GNSS RF-to-bits receiver for satellite navigation enthusiasts. The NUT4NT+ is connected to the PC by a USB 3.0 interface. The hardware is open source. The open source software provides the ability to set a receiver’s modes and frequencies, to capture all signals continuously, and to make an example of primary processing features.

We will be offering NUT4NT+ in a conventional four-channel board as well as a smaller board built to mount on the back of an Android mobile device. We’ve recently found ways to make the board much more affordable than previous iterations, without sacrificing performance.

The Android software is currently available on GitHub.
