JS-A56U9D High-Precision Multi-Band GNSS Module for RTK, Robotics, Mapping, and Smart Transportation

Compact JS-A56U9D GNSS receiver module with multi-band architecture for high-precision positioning in robotics and surveying..jpg

As industries increasingly rely on precise spatial awareness, high-performance GNSS receivers have become essential across robotics, surveying, transportation, and autonomous systems. The Jumpstar JS-A56U9D is engineered to meet these requirements by combining multi-band concurrent GNSS, RTK capability, and robust interference resistance within a compact module design

Multi-Constellation, Multi-Band Architecture

The JS-A56U9D processes signals from GPS, BDS, GLONASS, Galileo, and QZSS/SBAS simultaneously, enabled by its multi-band RF front-end. Concurrent operation ensures consistent performance and improved satellite geometry, particularly in urban or obstructed environments.

Supported signals include:

GPS: L1C/A, L2C
GLONASS: L1OF, L2OF
BDS: B1I, B2I
Galileo: E1-B/C, E5b

This broad compatibility provides a reliable foundation for applications requiring continuous, high-integrity positioning.

Centimeter-Level RTK Accuracy

When supplied with RTCM correction data, the JS-A56U9D achieves RTK Fixed solutions with centimeter-level horizontal accuracy (0.01 m + 1 ppm CEP).

· RTK convergence: <10 seconds

· Dynamic heading accuracy: 0.3°

· Velocity accuracy: 0.05 m/s

Both base and rover modes are supported through UART, RS232, USB, or I2C, enabling flexible deployment in static or mobile scenarios.

High Performance in Demanding Environments

Engineered with integrated TCXO, LNA, SAW, and RTC, the module maintains high sensitivity and fast acquisition:

· Cold start: 25–30 s

· Hot start: 2 s

· Tracking sensitivity: –167 dBm

These characteristics improve performance where signal multipath or attenuation is common, such as city centers, dense foliage, or vehicle-mounted installations.

Enhanced Hardware Integration and Interfaces

To support various embedded designs, the JS-A56U9D offers:

· UART (host communication)

· UART dedicated for RTCM/NMEA

· RS232 (optional model)

· USB (optional model)

· I2C interface

· Integrated high-gain antenna

Three variants—JS-A56U9D-T, JS-A56U9D-R, and JS-A56U9D-U—enable designers to select the appropriate interface configuration for their system architecture
