Product details
Garmin, a GPS antenna, is the preferred scheme for marine and vehicle positioning. It integrates GPS and GSM dual frequency bands, and with high precision and stable signal receiving ability, it can easily meet the complex positioning requirements in multi-mode applications.
Its GPS gain performance is particularly outstanding, up to 29dB, and the fluctuation range is strictly controlled within 3 dB. Accurate gain control fully demonstrates the exquisite design process of the product. In addition, the center frequency of the antenna has been accurately calibrated to 1575.42MHz, which is highly compatible with the working frequency of the GPS system to ensure the stability of signal reception.
The high gain design and stable gain fluctuation range complement each other, which greatly improves the signal capture ability of the antenna. In the complex and changeable electromagnetic environment, it can lock the GPS satellite signal quickly and accurately, and complete the signal receiving task efficiently, whether it is influenced by natural factors such as multipath effect or faced with man-made signal interference.
The right-handed circular polarization mode is adopted, which is a highlight of the antenna in GPS frequency band. Right-handed circular polarization can effectively reduce the multipath effect, that is, the interference caused by reflection and refraction during the propagation of signals, thus significantly improving the positioning accuracy and stability. In the marine scene, facing the complex water reflection environment, this polarization mode can ensure the pure reception of signals and provide users with reliable navigation information.
The signal-to-noise ratio (V. S.W.R) of GPS band is less than 1.8. By realizing the high matching between antenna and transmission line, signal reflection is reduced, transmission efficiency is improved, and finally more accurate and timely positioning effect is brought.
In GSM frequency band, the antenna adopts vertical polarization mode, which is specially designed for large-scale mobile communication base stations. Vertical polarization can enhance the stability and efficiency of signal reception, and ensure that the antenna can receive GSM signals continuously and stably during the mobile process, such as in vehicle applications, and provide uninterrupted communication services for users.
The gain of GSM band is 3.5dBi, and the moderate gain design not only enhances the signal receiving ability, but also is perfectly compatible with multi-mode applications. Whether it is the daily mobile communication demand or the signal strength requirement in a specific scene, the antenna can easily cope with it, providing users with a stable and reliable GSM signal receiving experience.
The signal-to-noise ratio (V. S.W.R) of GPS band is less than 1.8. By realizing the high matching between antenna and transmission line, signal reflection is reduced, transmission efficiency is improved, and finally more accurate and timely positioning effect is brought.
For GPS frequency band, the antenna is specially equipped with Fakra connector dedicated to automobile environment. Through customized design, it ensures that the antenna works stably when the vehicle is driving-even in the face of bumpy roads or complex driving environment, it can always maintain a stable connection and provide users with uninterrupted continuous positioning services.
For GSM band, the antenna is equipped with SMA-Male connector. The connector itself has the characteristics of stability and reliability, and can easily adapt to the connection requirements of various devices; It also supports customized services. No matter the interface size, material or other special requirements, it can be adjusted as needed to ensure the seamless connection between the antenna and the equipment.
Aiming at the two core scenarios of marine navigation and vehicle application, Garmin, a GPS antenna, provides efficient, accurate and stable positioning and communication support with excellent performance of dual-band (GPS/GSM) and multi-type connectors, and easily meets all kinds of complex needs, so it is a practical choice for users.
What scenes is this Garmin GPS antenna mainly suitable for?
It is mainly aimed at the two core scenarios of ship navigation and vehicle positioning, which can meet the positioning and communication requirements in complex environments and is the preferred scheme for these two scenarios.
What are the characteristics of connectors in GSM band?
SMA-Male connector is used in GSM band, which is stable and reliable and can adapt to all kinds of equipment; At the same time, it supports customized services, and the interface size and material can be adjusted according to the actual needs of users to realize seamless connection with equipment.
Can the antenna work normally in a complex electromagnetic environment?
Sure. The combination of high gain design and stable gain fluctuation range can help the antenna to lock the GPS satellite signal quickly and accurately in complex electromagnetic environment (such as multipath effect and man-made signal interference) and complete signal reception efficiently.
