NOKIA AYGE 475647A multi-GNSS receiver

The NOKIA AYGE 475647A is a high-performance multi-GNSS (Global Navigation Satellite System) dual-band receiver with an integrated antenna, designed to provide precise timing and positioning capabilities for telecommunications infrastructure. It is engineered for seamless integration into Nokia's AirScale base station ecosystem, serving as a critical component for network synchronization and reliable frequency/time distribution

• Multi‑GNSS Constellation Support: Simultaneously tracks multiple global satellite systems (e.g., GPS, GLONASS, Galileo, BeiDou) to maximize satellite availability and improve time‑to‑first‑fix (TTFF) under diverse environmental conditions.

• Dual‑Band Reception: Operates on two frequency bands (e.g., L1/L2 or L1/L5) to mitigate ionospheric errors and enhance positioning/timing accuracy, particularly in regions with variable atmospheric conditions.

• Integrated Antenna: Combines the GNSS receiver and antenna in a single, ruggedised enclosure, simplifying outdoor installation and reducing deployment complexity.

• Telecom‑Grade Timing Output: Provides a highly stable, GNSS‑disciplined 1‑Pulse‑Per‑Second (1PPS) and time‑of‑day (ToD) reference for synchronising base station radio frames, meeting stringent 3GPP specifications for LTE and 5G TDD operation.

• High Sensitivity & Fast Acquisition: Advanced signal processing and assistance technologies (e.g., A‑GNSS) enable rapid satellite lock even in weak‑signal or obstructed‑view scenarios.

• Carrier‑Grade Reliability: Designed with industrial‑grade components; supports wide operating temperatures and voltage ranges for continuous outdoor deployment in cell towers and remote telecom shelters.

• Hot‑Swap Support: The receiver module is hot‑swappable, enabling replacement without powering down the base station, thus minimising service disruption.
