Jumpstar Introduces X43: Ruggedized High-Precision GNSS Solution for UAVs, Robotics and Surveying

In an era where autonomous systems demand unyielding accuracy, Jumpstar GNSS proudly unveils the X43—a breakthrough ultralight compact RTK GNSS receiver. Engineered for seamless integration into drones, robots, and precision-driven applications, the X43 combines all-constellation, all-frequency capabilities with centimeter-level precision, setting new standards in the GNSS mass market. At under 25g and measuring just 43.8 x 34.0 x 11.5mm, it's the ideal choice for space-constrained setups without compromising performance.

Unmatched Features for Demanding Environments

The X43 boasts a high-performance chipset with 789 hardware channels for simultaneous multi-constellation tracking, including GPS, GLONASS, BDS, Galileo, QZSS, NavIC, and SBAS. Its ultra-low latency under 10ms ensures real-time responsiveness, crucial for autonomous navigation and control. Advanced technologies like AIM+ for interference and spoofing mitigation, LOCK+ for shock/vibration resistance, IONO+ for ionospheric protection, and APME+ for multipath separation make it excel in complex urban or industrial settings.

Key highlights include:

● Centimeter Precision: 0.6cm + 0.5ppm horizontal RTK accuracy, 1cm + 1ppm vertical.

● Heading Capabilities: Dual-antenna mode delivers 0.15° heading and 0.25° pitch/roll at 1m spacing.

● Fast Acquisition: Cold start <35s, RTK initialization in 7s.

● Protocols Supported: NMEA 0183, SBF, RTCM v3.x, CMR/CMR+.

● Integrated Perks: Built-in TCXO, LNA, and TF card slot (up to 32GB) for data logging.

With a navigation update rate up to 20Hz and velocity accuracy of 0.03m/s RMS, the X43 is future-proof, even supporting Galileo OSNMA for enhanced security.

Easy Setup and Operation with RxTools

Getting started is straightforward. Download RxTools from Septentrio's site and connect via USB or serial (default 115200 baud). Use RxControl for firmware checks (latest: 1.0.0-beta2 as of Feb 2025) and upgrades. View satellite status, SNR, differential data, and positioning in real-time. Configure tracking satellites/frequencies (e.g., GPS+GLONASS+Galileo+Beidou) and PVT solutions via intuitive menus or commands like sst,GPS+Glonass+Galileo+Beidou.

Optimize performance with anti-interference (enable Class1 mitigation), multipath reduction, and 10° elevation masks. For RTK rover mode, use Datalink for differential input from NTRIP or serial sources, achieving fixed solutions quickly. Log NMEA/SBF data to TF cards or PCs for analysis.

Versatile Applications Across Industries

The X43 shines in UAVs for aerial mapping, base stations (X43-A model), smart logistics, geomatics surveying, precision agriculture, geological monitoring, and vehicle-mounted systems. Its dual-antenna heading (X43-AH) enables precise orientation for autonomous robots and driving. Whether mitigating urban multipath or handling vibrations, it's built for real-world challenges.

Troubleshooting and Support

For issues, generate diagnostic reports via RxControl (Ctrl+C) or commands. Log Support SBF at 10Hz for tech analysis—simple steps ensure quick resolutions.
