Amungo Navigation NUT2NT+ is an open source hardware four-channel, all-frequency, GNSS RF-to-bits receiver for precision, satellite-based positioning. Connected to the right antennas, the board can achieve centimeter positioning resolution by connecting to multiple navigation satellite systems including GPS, GLONASS, Galileo, BeiDou, and IRNSS.
Amungo claims that while several startups and large companies already offer proprietary GNSS positioning solutions NUT2NT+ is the only open source option in this class of GNSS devices.
NUT2NT+ key features and specifications:
- Receiver chip – NTLab NT1065 4-Channel RF Front-End IC
- FPGA – Lattice ECP5 with 12K LUTs + 28 DSP blocks (LFE5U-12) opened for custom design
- USB – 1x USB 3.1 Type-C port via CYUSB3014 USB 3.0 controller:
- Clock – 10 MHz TCXO, soldered
- RF inputs – 2x bands dedicated; – 5 dB referred noise floor
- ADC – 2-bit resolution up to 99 MHz
- Samples transfer – Continuous full stream, from 10 to 50 Mbytes/sec
- Standards – GPS, GLONASS, Galileo, BeiDou, IRNSS, and future standards
- Band: L1/L2/L3/L5, G1/G2/G5, B1/B2, E1/E5, and future bands
- Power injector circuit – For antennas with a DC short like a dipole or PIFA. The circuit is software-controllable.
- Power consumption – 5 V/0.3 A from USB
- Dimensions – 100 x 50 x 10 mm
The board comes with optional enclosures and antennas, as well as open source software for spectrum and GNSS signal monitoring, USB controller firmware, and FPGA code which you’ll find on Github.
Some of applications made possible by this board includes a GNSS Sensor for autonomous driving when combined with a RA125 antenna and Jetson TX2 board, or a GNSS multi-band “Black Box” Logger with RockPro64 or other small factor SBCs.
NUT2NT+ GNSS board launched on Crowd Supply a few days ago with a $15,000, and so far they’ve reached a little over half of the target. Rewards now start at $320 for an NUT2NT+ board only, but you may also consider adding accessories such as antennas ($80 and up), $20 for an RF cable connecting to the antenna, or enclosures. Shipping for the board is free to the US, but adds $30 to the rest of the world, and backers can expect their kit to be shipped by the end of September 2019 if everything goes according to plan.
