Gps Antenna categories (GPS Antenna categories and their applications)

With the rapid development of Global Positioning system (GPS) technology, GPS antennas, as the key equipment to receive GPS signals, are increasingly widely used. In this paper, the categories of GPS antennas are introduced in detail, and their applications in different fields are discussed.

Overview of GPS Antenna

GPS antenna is a device that receives GPS satellite signals. Its main function is to convert the received weak GPS signals into electrical signals for subsequent processing. The performance of GPS antennas directly affects the positioning accuracy and stability of GPS equipment.

GPS antenna category

1. Classify by structure

(1) Spiral antenna: suitable for hand-held GPS equipment, with the characteristics of small size and light weight.

(2) Rod antenna: commonly used in vehicle or shipboard GPS equipment, with good receiving performance.

(3) Plate antenna: widely used in fixed GPS equipment, such as base station and measurement equipment, with the characteristics of stable receiving performance and high gain.

(4) Array antenna: composed of multiple antenna elements, it is suitable for high-precision applications, such as aerospace, UAV and so on.

2. Classify by working frequency

(1) L-band antenna: it mainly receives the L-band signal of GPS satellite, which is the most commonly used type of GPS antenna at present.

(2) other frequency band antennas: such as receiving antennas of other satellite navigation systems, such as GLONASS, Galileo, etc.

3. Classify by application scenario

(1) Civil GPS antenna: widely used in smart phones, vehicle navigation, measuring instruments and other fields.

(2) Professional GPS antenna: suitable for aerospace, UAV, marine fishery and other high-precision applications.

Characteristics and application fields of all kinds of GPS antennas

1. Spiral antenna: small size, light weight, suitable for handheld devices and mobile applications, often used for outdoor exploration, hiking and other scenes.
