What is a GPS antenna?
1. Space part
The space part of GPS is composed of 24 satellites (21 working satellites; 3 spare satellites). It is located at a distance of 20,200km from the earth’s surface and has an operating period of 12h. The satellites are evenly distributed on 6 orbital planes (4 on each orbital plane), and the orbital inclination is 55°.
The distribution of satellites allows more than 4 satellites to be observed anywhere in the world and at any time, and navigation information can be pre-stored in the satellites. GPS satellites due to atmospheric friction and other problems, the navigation accuracy will gradually decrease over time.
2. Ground control system
The ground control system is composed of a monitor station (Monitor Station), a master control station (Master Monitor Station), and a ground antenna (Ground Antenna). The main control station is located in Colorado. Springfield, Colorado.
The ground control station is responsible for collecting the information transmitted by the satellite, and calculating the satellite ephemeris, relative distance, atmospheric correction, and other data.
3. User equipment part
The user equipment part is the GPS signal receiver. Its main function is to be able to capture the satellites to be tested and selected according to a certain satellite cut-off angle and track the operation of these satellites.
After the receiver has captured the tracked satellite signal, it can measure the pseudo-distance from the receiving antenna to the satellite and the rate of change of the distance, and demodulate data such as satellite orbit parameters.
Based on these data, the microprocessor in the receiver can perform positioning calculations according to the positioning calculation method, and calculate the longitude, latitude, altitude, speed, time, and other information of the user’s geographic location.
The receiver hardware, internal software, and GPS data post-processing software package constitute complete GPS user equipment.
The structure of the GPS receiver is divided into two parts, an antenna unit, and the receiving unit. The receiver generally adopts two kinds of DC power supply inside and outside the machine.
The purpose of setting the internal power supply is to continuously observe without interrupting the external power supply. The internal battery is automatically charged when the external power supply is used. After shutting down, the internal battery provides power to the RAM memory to prevent data loss.
Various types of receivers are getting smaller and lighter in size and lighter, which is convenient for field observation. The second is the user receiver. There are two types of single-frequency and dual-frequency. However, due to price factors, most users buy single-frequency receivers.
