• High Precision & Fast Fix: Delivers 1.5m horizontal positioning accuracy (undisturbed) and completes cold start first fix in just 30s, balancing precision and efficiency for time-sensitive tasks.
• Low Power & Compact Design: Consumes only ≤60mA@5V, ideal for battery-powered devices (e.g., small drones); its compact size (Φ46mm * 18mm) saves installation space, adapting to space-constrained scenarios.
• Standardized Interface & Protocol: Equipped with a universal UART 232 interface (5-pin JST connector) and supports the widely used NMEA0183 protocol, ensuring easy integration with most flight controllers, industrial PLCs, and navigation devices.

Leveraging its high precision, anti-interference capability, and compact design, the product is widely applicable to scenarios requiring reliable positioning and timing:

• Unmanned Aerial Vehicles (UAVs): Provides stable positioning for FPV drones, surveying drones, and agricultural drones—resisting interference from ground electromagnetic sources and ensuring flight safety.
• Industrial Automation: Supports AGVs (Automated Guided Vehicles), robotic arms, and smart factory equipment, delivering high-precision positioning to optimize workflow efficiency.
• Intelligent Transportation: Assists in vehicle-mounted navigation, fleet management, and low-speed autonomous driving (e.g., campus shuttles), maintaining positioning accuracy even in urban canyons (signal obstruction) or near high-voltage lines (electromagnetic interference).
• Precision Agriculture: Guides agricultural machinery (e.g., planters, harvesters) to achieve accurate row spacing and operation paths, improving crop yield and resource utilization.
• Communications & Power Sectors: Offers high-precision timing (≤20ns RMS) for base stations, power grids, and data centers, ensuring synchronization of signal transmission and transaction records.

A1: It supports four major global satellite systems: BDS (BeiDou), GPS, GLONASS, and Galileo.

A2: Yes, accuracy differs based on environmental conditions:

• Undisturbed environment: Horizontal ≤1.5m, Elevation ≤2.5m;
• Under interference: Horizontal ≤10m, Elevation ≤10m.

A3: Its anti-interference capability is 65dBc. It can effectively handle satellite signal interference, physical obstruction (e.g., buildings, trees), and multipath effects—maintaining positioning stability even in harsh electromagnetic or occluded environments.

A4: It requires a 5V power supply (via the 5-pin JST XH-2.54-5T connector) and has a power consumption of ≤60mA@5V. Do not supply power beyond the rated 5V range to avoid device damage.

A5: It is equipped with 1 x UART 232 interface (connector type: 5-pin JST XH-2.54-5T) and supports the NMEA0183 protocol for positioning and timing data output.

A6: The cold start first fix time is 30s (2σ).

A7: Three key requirements must be met:

1. The installation position must ensure a 180° sky viewing range for the antenna (to capture satellite signals);
2. Avoid proximity to metal objects or electromagnetic interference sources (e.g., motors, high-voltage cables);
3. The antenna installation surface must be kept horizontal.

A8: No. The device contains sensitive electronic components, and unauthorized removal of the housing is prohibited—this may damage internal parts or void functionality.

A9: Its timing accuracy is ≤20ns (RMS), suitable for scenarios requiring high-precision time synchronization (e.g., communications base stations, power grids).

A10: Its external dimensions are Φ46mm * 18mm (circular shape), making it compact for space-limited installations.
