Nokia FYGB 472748A GPS GNSS Receiver Antenna

Product Details 

• Multi - system support: It can support both GPS and GLONASS satellite systems simultaneously, receiving signals from these two systems. Compared with antennas that only support a single system, its positioning and timing reliability and accuracy are higher. Even when there is signal occlusion or a fault in one of the satellite systems, it can still ensure basic functions through the other system, ensuring the stable acquisition of position and time information in various complex environments.
• Integrated design: It has a built - in receiver. This integrated design reduces the need for external component connections, reducing the risk of signal loss and interference during signal transmission. At the same time, it also improves overall stability and reliability. During installation, it only needs to be placed outdoors to obtain satellite visibility and directly connected to the system module, simplifying the installation process and saving installation space and costs.
• Wide temperature range adaptability: The operating temperature range is from - 40℃ to + 85℃. It can work normally in a variety of harsh climate conditions such as extreme cold and high temperature, with strong environmental adaptability. It can meet the usage requirements in different regions and seasons. Whether in the cold polar regions or the hot desert environment, it can operate stably, ensuring the normal operation of the communication system.
• High - precision positioning and timing: As a key device for base station positioning and timing, this antenna can provide high - precision positioning and timing services for base stations, ensuring that the time synchronization accuracy between base stations reaches a high level, thereby reducing signal transmission delay and error, improving the performance and reliability of the entire communication network, helping to improve communication quality and reduce the occurrence of problems such as call interruption and signal distortion.
• High - quality materials and craftsmanship: Nokia has rich experience and strict quality control standards in antenna design and manufacturing. The use of high - quality materials and advanced manufacturing processes can effectively improve the antenna's signal reception ability, reduce the occurrence of signal loss, and also ensure the antenna's durability and service life, reducing maintenance costs and replacement frequency.

FAQ

Q1: What is the main function of Nokia FYGB 472748A? 

A1: It is a GNSS receiver antenna for Nokia Flexi base stations, used to receive GPS/GLONASS satellite signals and provide high-precision 1PPS clock synchronization for telecom BTS.

Q2: Can FYGB 472748A work if GLONASS signal is blocked? 

A2: Yes. It supports automatic fallback to GPS-only mode, so the base station timing still works when GLONASS satellites are unavailable.

Q3: What is the environmental protection grade of FYGB 472748A? 

A3: IP67 rated. It can be deployed outdoors, resistant to dust, rain and moisture, suitable for telecom tower and mast installation.

Q4: Which Nokia base station series is FYGB 472748A compatible with? 

A4: It is designed for Nokia Flexi Multiradio BTS series, commonly matched with Flexi RRH / baseband units for mobile communication sites.

Q5: What cable is required for FYGB 472748A installation? 

A5: It uses dedicated Nokia GNSS timing cable (such as FTSP series) to carry power and 1PPS timing signal between antenna and BBU.
