**Core Capabilities** * Precision Navigation: Supports multi-band GNSS for reliable flight control and autonomous positioning. * Integrated Remote ID (CubeID™): Provides real-time broadcast of identification and telemetry data to comply with FAA and international tracking requirements * Secure & Compliant: Designed to meet NDAA requirements, making it authorized for use in government-restricted and defense-related applications. **Here4 Blue vs. Here4** The Here4 Blue retains the industry-leading GNSS performance of the standard Here4 but is differentiated by its focus on regulatory transparency and manufacturing security: * Bluetooth 5.2 and CubeID™: Features a dedicated 2.4 GHz nRF module for high-reliability Remote ID broadcasting, enabling FAA compliance without external hardware. * Secure Supply Chain: To meet NDAA standards, the Here4 Blue is manufactured in the United States or allied countries (typically the USA or Taiwan), ensuring suitability for government and enterprise projects. **Testing and Compliance** The Here4 Blue has undergone extensive third-party laboratory testing to ensure it meets international safety and radio standards, including: * Radio Interference: FCC (USA), CE (EU), UKCA (UK), RCM (Australia/NZ) * Material Safety: RoHS (Hazardous Substances), California Proposition 65 (Chemical Disclosure)
