GNSS/GPS antennas: The key component for precise positioning
GNSS/GPS antennas play a crucial role in determining position. They are the interface between Global Navigation Satellite Systems (GNSS) such as GPS, GLONASS or Galileo and the receivers that receive and process the satellite signals. With the advancement of GNSS technology, more precise positioning is becoming possible, making GNSS/GPS antennas increasingly important.
GNSS/GPS antennas are used to receive the signals from the satellites and relay them to the receiver. It is important that the antennas have a high reception power in order to detect even weak signals in urban areas or under unfavorable conditions. They should also have good directional characteristics to minimize interference from reflections or multipath propagation.
There are different types of GNSS/GPS antennas that can be selected depending on the application and environment. The most common types of antennas are the patch antennas, which are designed as area radiators and offer high reception power. These antennas are compact and therefore well suited for use in mobile devices such as smartphones or navigation systems.
Another type of antennas are the active antennas, which have an integrated amplifier and thus have a higher sensitivity. This allows them to better detect weak signals and enables more precise positioning. Active antennas are often used in professional applications such as land surveying or precision agriculture.
In addition to the reception power, the antenna positioning is also of great importance. Optimal placement of the antenna can significantly improve the reception quality. Care should be taken to ensure that the antenna has a clear view of the sky and is covered as little as possible by buildings, trees or other obstacles. In some cases, it may also be useful to use multiple antennas to provide better signal coverage.
The advancement of GNSS technology also makes it possible to use GNSS/GPS antennas in more and more application areas. For example, they are used in autonomous vehicles to enable precise positioning for autonomous driving. GNSS/GPS antennas are also used in aviation for precise navigation.
Overall, GNSS/GPS antennas are an indispensable component for precise positioning. Due to the continuous development of GNSS technology, better and better antennas are being developed that enable more accurate positioning. This opens up new possibilities in various application areas such as navigation, surveying or precision agriculture.

What is a GNSS/GPS antenna and how does it work?
A GNSS/GPS antenna is a special antenna that is used to receive signals from global navigation satellite systems (GNSS) such as the Global Positioning System (GPS).
The antenna consists of a metallic radiator and a receiver known as an LNA (Low Noise Amplifier). The radiator is designed in such a way that it captures the signals from the satellites and forwards them to the LNA. The LNA then amplifies the weak signals to make them usable for further processing by the GNSS/GPS receiver module.
The antenna uses a technology called "directionality" to receive signals from the satellites. This means that it is designed so that it only receives signals from a certain direction and blocks signals from other directions. This allows the antenna to minimize interference from other sources and enables precise positioning.
In addition, the antenna can also support various GNSS frequency bands, including L1 (1575.42 MHz), L2 (1227.60 MHz) and L5 (1176.45 MHz) for GPS. This enables optimum performance and accuracy in positioning.

What is the difference between active and passive GNSS/GPS antennas?
Active GNSS/GPS antennas have a built-in amplifier that amplifies the weak GNSS/GPS signal before it is sent to the receiving device. This enables better signal quality and improved reception performance, especially in environments with poor signal conditions such as in urban areas or near obstacles.
Passive GNSS/GPS antennas, on the other hand, do not have a built-in amplifier and send the received signal directly to the receiving device. They are generally smaller and simpler than active antennas, but have a lower reception performance and are less effective in difficult signal environments.
The choice between active and passive antennas depends on the individual requirements and the signal conditions. In situations where a stronger signal is required, an active antenna is recommended, while passive antennas may be sufficient for applications with good signal conditions.
