Overview
This GPS Module is a high-performance positioning and navigation module based on the ATGM336H-5N. It supports BDS (BeiDou), GPS, GLONASS, and QZSS, and can simultaneously receive signals from these satellite navigation systems for joint positioning. It is designed for ROS robot projects and drone navigation development, with onboard USB Type-C/USB connectivity for quick setup with a computer, Raspberry Pi, Jetson, and other common platforms.
Key Features
- Supports four satellite systems: BDS, GPS, GLONASS, QZSS
- 32 channels; supports single-system positioning and multi-system joint positioning in any combination
- Positioning accuracy: 2.5 m (CEP50); tracking sensitivity: -162 dBm
- Pi-type antenna network design: impedance matching 50 ohm; antenna standing wave ratio (VSWR) lower than 1.6
- Built-in USB interface and serial (UART) interface for plug-and-play connection
- Cold start time: 32 s
- GNSS antenna connection via SMA socket (outer screw and inner hole), compatible with active antennas
- Onboard reset button, pulse output indicator, 5V power indicator, and super-capacitor for improved stability during unstable power supply
- ROS-related tutorial materials, debugging software, and source codes provided by Yahboom

Details


The Yahboom ATGM336H-5N GPS module ships with an external antenna for quick GNSS signal reception and setup.

Onboard USB and an SMA antenna connector make it easy to integrate into robot and drone navigation builds.

Multi-constellation support improves positioning reliability by combining signals from GPS, BDS, GLONASS, and QZSS.




Designed for development workflows, the module combines multi-mode GNSS reception with plug-and-play USB and UART access.

Clear onboard labeling helps with wiring: Type‑C/USB for power and data, UART pins for embedded integration, plus status indicators and reset.

Connect to a computer or Raspberry Pi over USB for fast configuration, testing, and data logging.

UART pin access supports direct integration with common microcontroller development boards when USB isn’t needed.




Standard NMEA-style outputs include coordinates, altitude, accuracy references, and UTC time for robotics and navigation applications.


Official tutorials, manuals, and example resources are provided to speed up development and ROS integration.

Free Windows PC software supports module debugging with live sky view, satellite signal levels, and coordinate data.

The ATGM336H-5N GPS antenna impedance chart lists S11 return loss and standing wave ratio near 1.579 GHz for quick matching checks.

The Yahboom ATGM336H-5N GPS module comes with a separate GPS antenna and cable for flexible mounting and cleaner wiring.

The Yahboom ATGM336H-5N GPS module has a compact footprint (29.5 mm wide by 42 mm tall) with an overall thickness of about 4 mm for easier mounting.

The ATGM336H-5N module supports multi-GNSS (GPS/BDS/GLONASS/QZSS), uses a 5V, GND, TX, RX pinout, and offers 1–10Hz update rates with configurable baud settings.

The GPS positioning module kit includes an active antenna, a Type‑C data cable, and an accessory screw set for installation.

The Yahboom ATGM336H-5N GPS kit includes a GPS positioning module, 10-axis IMU inertial navigation module, active antenna, USB-C cable, and pin headers for easy integration.
