GEM1205

The Allystar GEM1205 is a high-performance, compact dual-band (L1/L5) multi-system GNSS positioning module designed by Allystar Technology. It is widely used in automotive logistics, IoT telemetry, smart agriculture, drones, and industrial asset tracking systems.

Key Technical Specifications

• Supported Constellations: Full multi-system concurrent tracking for GPS, NavIC (IRNSS), BDS (Beidou), GLONASS, Galileo, and QZSS. 
• Integrated Antenna: Built-in high-performance dual-feed patch antenna designed to mitigate multi-path interference, especially in dense urban environments.
• Smart Antenna Logic: Embedded circuitry that supports auto-detection and auto-switching between the internal patch antenna and an external active antenna. 
• Power Consumption: Features an ultra-low thermal signature, drawing only ~40 mA during active dual-band tracking mode. 
• Form Factor: Compact footprint measuring 26.7 mm × 18.5 mm × 7.0 mm. 
• Signal Enhancements: Onboard LNA (Low Noise Amplifier) and SAW filters for high sensitivity, along with support for AGPS, DGPS, and SBAS (including GAGAN, WAAS, EGNOS, and MSAS). 
• Advanced Features: Supports programmable hardware geofencing and NavIC/IRNSS message broadcasting services.
