The Allystar TAU1113 is a cost-effective, low-power single-band GNSS positioning module designed for space-constrained and battery-operated applications. Based on Allystar's proprietary CYNOSURE III Lite GNSS SoC architecture (HD812X chip), it combines high-sensitivity satellite tracking with minimal current draw, making it highly optimal for large-scale Internet of Things (IoT) deployments.
Technical Specifications
• Supported Constellations: GPS/QZSS, BDS (Beidou), GLONASS, Galileo, and SBAS.
• Form Factor: Ultra-compact 18-pin LCC package.
• Dimensions: 10.1 mm × 9.7 mm × 2.5 mm.
• Position Accuracy: 1.5 m CEP standalone (down to < 1.0 m CEP with SBAS support).
• Power Consumption: Active tracking requires only 16 mA (GPS/QZSS), with a standby backup current of just 15 µA.
• Tracking Sensitivity: -163 dBm.
• Update Rate: 1 Hz to 5 Hz.
• Operating Voltage: 2.0V to 3.63V.
• Interface: UART (NMEA protocol).
Key Features
• Integrated Components: Features a built-in SAW filter, Low Noise Amplifier (LNA), internal flash memory, and an onboard antenna supervisor.
• Antenna Flexibility: Out-of-the-box compatibility with both active and passive external antennas.
• Fast Acquisition: Supports Allystar’s free A-GNSS (Assisted GNSS) service for rapid Time-to-First-Fix (TTFF) startup.
• Hardware Compatibility: Engineered to be pin-compatible with earlier Allystar modules (like the TAU1103 and TAU1105) as well as mainstream industry-standard 1010-sized modules to simplify drop-in hardware migrations.
Common Applications
Due to its strict power constraints and small physical profile, it is heavily used in:
• Asset Tracking: Shipping containers, logistics, and livestock tracking.
• Telematics: Fleet management systems and OBD dongles.
• Portable Devices: Wearables, shared micro-mobility (scooters/bikes), and small battery-operated electronics.
