Key Features
Multi-GNSS Compatibility & Flexible Positioning Modes
Multi-GNSS Compatibility & Flexible Positioning Modes
Supports a wide range of GNSS systems including GPS, BDS, Galileo, GLONASS, QZSS, and SBAS, enabling flexible selection of positioning modes (single-mode or multi-mode combination) based on project requirements. This ensures superior navigation stability and broader signal coverage.
Compact Design & Lightweight Construction
Compact Design & Lightweight Construction
Boasts a compact size of 25mm×25mm×7.8mm (±0.3mm) and a lightweight of 11g, paired with a high-performance small-volume antenna. The miniaturized design maintains full functionality, making it ideal for small devices like traversers, light fixed-wing UAVs, and compact industrial equipment.
Strong Star-Search Capability & Weak Signal Adaptability
Strong Star-Search Capability & Weak Signal Adaptability
Features a T-antenna network design with 50Ω impedance matching and antenna VSWR <1.5, maximizing signal reception efficiency. With high sensitivity (-166dBm for tracking & navigation) and fast startup (1s hot start), it achieves fast and accurate positioning even in weak signal environments such as cities, canyons, under elevated roads, and inside vehicles.
High-Precision Data Output & Versatile Applications
High-Precision Data Output & Versatile Applications
Delivers precise data including 1.5m CEP horizontal position accuracy, 0.05m/s velocity accuracy, and 30ns RMS time pulse accuracy, providing detailed latitude, longitude, speed, and time information. Widely applicable to UAVs, unmanned vehicles, vehicle monitoring, ship navigation, etc., with stable operation in -40°C to +70°C and storage tolerance of -55°C to +85°C.
Parameters

The YM-250 is capable of fast and accurate positioning in weak signal areas such as cities, canyons, and under elevated viadas, as well as inside the car. It can be widely used in UAV, unmanned vehicle, crossing machine, vehicle monitoring, bus station announcement, vehicle navigation, ship navigation, notebook navigation, driving recorder and other products that need to be positioned.

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.
