GNSS, SAM-M10Q
Description
1. Product Summary
1.1. Product Description
SAM-M10Q is a high-performance GNSS module from u-blox featuring an integrated patch antenna and multi-band support for four global constellations (GPS, GLONASS, Galileo, BeiDou). The compact 15.5 × 15.5 × 6.3 mm design with onboard LNA and SAW filter ensures high sensitivity, strong anti-jamming capability, and ease of integration into embedded and portable systems.
1.2. Product Features
- Concurrent reception of GPS, GLONASS, Galileo, and BeiDou signals.
- Integrated patch antenna and low-noise amplifier (LNA) for high sensitivity.
- Built-in SAW filter providing excellent out-of-band jamming immunity.
- Ultra-low power consumption of ~38 mW in continuous tracking mode.
- Compact module size: 15.5 × 15.5 × 6.3 mm.
- Supports UART and I²C interfaces.
- Pin-compatible with u-blox SAM-M8Q.
- Integrated spoofing and jamming detection algorithms.
- Supports Time Pulse (1PPS) output for synchronization applications.
1.3. Applications
- Drones and UAVs: Reliable multi-GNSS tracking in dynamic environments.
- IoT / Asset tracking: Low-power operation ideal for battery-based systems.
- Portable devices: Navigation and timing applications.
- Automotive and industrial systems: Positioning, telemetry, and sensor synchronization.
- Consumer electronics: Wearables and handheld navigation devices.
