Overview
Key Features
Tri-System Fusion & Flexible Positioning Modes
Supports combined positioning of GPS+BDS+Galileo, with flexible mode selection (single-mode or multi-mode combination) according to project requirements, ensuring superior navigation stability and coverage.
Ultra-Compact & Lightweight Design
Adopts a high-performance small-volume antenna and miniaturized structure, with dimensions of 18×18×7.8mm (±0.3mm) and weight as low as 8g. Ideal for small traversers, loop machines, and light fixed-wing UAVs without compromising performance.
Superior Star-Search Performance
Features a T-antenna network design with 50Ω impedance matching and antenna standing wave ratio <1.5, maximizing signal reception capability. With high sensitivity (-166dBm for tracking) and fast acquisition (hot start in 1s), it ensures strong and accurate positioning even in complex environments.
High-Precision Data Output
Delivers accurate location (1.5m CEP horizontal position accuracy), velocity (0.05m/s accuracy), and time information (time pulse signal RMS 30ns). Provides comprehensive data including latitude, longitude, speed, and time for professional application needs.
Parameters
The YM-181Q GNSS module uses the latest generation of Ublox chip M10 with strong performance and faster star search speed, up to 32 satellites can be used for accurate positioning and on-board high-performance geomagnetic compass sensor QMC5883L.
Functional characteristics
All three kinds of positioning in one, better navigation
GPS+BDS+GALILEO joint positioning, flexible choice, you can choose to use the selection of positioning mode, you can choose single mode positioning, multi-mode combination positioning according to project requirements.
Small size and light weight
Using high performance small volume antenna, miniaturized design, performance does not shrink. Light weight up to 11g, ideal for small traverser/loop machine/light fixed wing use.
Powerful star search performance
T-antenna network design, impedance matching (50Q), antenna standing wave ratio less than 1.5, play the module receiving power advantage, so that the star search performance is strong, accurate positioning.
Get accurate data
Precise position can be obtained by latitude and longitude, and speed and time information can be learned.
