NANO RTK Receiver

Overview

NANO RTK Receiver

NANO RTK Receiver is the latest high-precision RTK receiver based on Allystar’s latest generation GNSS SoC. It can simultaneously support tracking all visible navigation satellites, including GPS, QZSS, BDS, GALILEO, GLONASS, and IRNSS.

It support RTK base and rover options.

You could choose Helix antenna and Survey antenna for your applications.

It has two interface: USB serial port and 6P connenctor. It support Bluetooth (BLE and Bluetooth Classic SPP).

Note: only SKU: NANO-BT-00 support bluetooth.

Compaible with:

Ardupilot PX4

SW Maps Mapit GIS

NANO RTK Receiver Connector NANO RTK Receiver Pin Map

By default, NANO series supports three types of external connections: Bluetooth, UART, and USB connection. For SKU: NANO-BT-00 Receiver, support the following connection:

Connection Remark
USB C Input: RTCM, Binary, Command
Output: Binary, RTCM, NMEA
Bluetooth Input: RTCM, Binary, Command
Output: Binary, RTCM, NMEA
6P UART Input: -
Output: RTCM, NMEA

Other NANO series (the following sku) do not support Bluetooth connection, but the 6P UART can fully support data input and output.

NANO-DG-xx, NANO-HRTK-00

Connection Remark
USB C Input: RTCM, Binary, Command
Output: Binary, RTCM, NMEA
Bluetooth -
6P UART Input: RTCM, Binary, Command
Output: Binary, RTCM, NMEA

Application

Work with other devices

Telemetry radio for Base station Connect telemetry radio device with RTK Receiver via 6P connector.

NANO RTK Receiver with Telemetry Radio

Ardupilot setup

NANO RTK Receiver support to use on autopilot.
For example,NANO is connected to the autopilot’s SERIAL4 port, it should work with :

SERIAL4_PROTOCOL = 5

GPS1_TYPE = 5
