Key Features
U-blox M10 Platform
The modern GNSS platform provides high sensitivity, fast acquisition and reliable positioning for FPV and autonomous applications.
Multi-Constellation Reception
Supports GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS for improved satellite availability.
Low Power Consumption
Power consumption of approximately 25mW makes the module suitable for battery-powered aircraft and mobile navigation devices.
Built-in Flash Memory
Customized baud rate, update rate and protocol settings can be stored in flash memory and retained after a power cycle.
Up to 18Hz Update Rate
A configurable navigation update rate supports dynamic FPV aircraft, autonomous vehicles and mobile positioning systems.
1PPS Timing Output
The dedicated one-pulse-per-second output supports precise timing and synchronization requirements.
Integrated Ceramic Antenna
The built-in 25 × 25mm ceramic patch antenna provides a compact integrated positioning solution.
Positioning Status LED
The onboard LED provides a visible indication when the module has achieved a valid 3D positioning fix.
Technical Highlights
Concurrent Multi-GNSS Positioning
The BU-1025TF supports concurrent reception from multiple navigation systems, including GPS, GLONASS, Galileo and BeiDou. Access to more visible satellites helps maintain positioning availability in complex operating environments.
High-Sensitivity U-blox M10 Receiver
The U-blox M10 platform provides tracking sensitivity of up to −167dBm. This enables reliable satellite tracking for FPV drones, bait boats and other mobile navigation equipment.
Built-in Configuration Memory
Configuration settings can be written to the onboard flash memory and retained after the module is restarted. Supported settings include the baud rate, navigation update rate and output-message configuration.
Low-Power GNSS Operation
Power consumption of approximately 25mW reduces the load on the aircraft or vehicle power system, making the module suitable for compact battery-powered positioning applications.
UART and NMEA Integration
The UART TTL interface supports configurable baud rates from 4800 to 921600bps. NMEA 0183 and UBX protocol support simplifies integration with flight controllers, navigation controllers and embedded systems.
Compact Integrated Antenna Design
The receiver, ceramic patch antenna, backup power component and positioning indicator are integrated into a compact 25.3 × 27.5mm module for space-limited FPV installations.
