Types of GPS in China

China has developed its own satellite navigation system called Beidou to provide accurate location and timing services for users worldwide. The Beidou system was fully completed in 2020, and since then, it has provided advanced GPS services for various applications, including transportation, agriculture, and emergency rescue. Here are some types of GPS in China that are worth exploring:

• Handheld GPS

  Handheld GPS devices are portable and lightweight. They are designed for hiking, hunting, and other outdoor activities. Handheld GPS devices have durable and waterproof features. They also have long battery life. Some common handheld GPS devices include the Garmin GPSMAP 66i and the Magellan eXplorist 310.

• Smartphone GPS

  Smartphones are equipped with built-in GPS receivers that allow users to access location-based services and navigation apps. Users can use their phones to get directions, track workouts, and find nearby places. The GPS quality in smartphones might not be as accurate as other dedicated GPS devices. However, they are convenient and suitable for casual use. Common navigation apps in smartphones include Google Maps and Apple Maps.

• Car GPS

  Car GPS are integrated into the dashboard of the vehicle. They provide turn-by-turn voice directions, real-time traffic updates, and points of interest. Car GPS systems are designed specifically for road navigation and offer features like route optimization and lane guidance. Popular car GPS systems include the Garmin DriveSmart series and the TomTom GO series.

• Surveying GPS

  Surveying GPS are used in land surveying and geomatics for high-precision location measurements. They operate on GNSS (Global Navigation Satellite System) and can receive signals from multiple satellite systems, including GPS, GLONASS, Galileo, and BeiDou. Surveying GPS provide accurate position data for mapping, construction, and other engineering applications. Some common surveying GPS devices include Trimble R10 and Topcon HiPer SR.

• Marine GPS

  Marine GPS are used in boats and ships for navigation, chart plotting, and tracking. They ensure safe navigation by providing accurate location information, even in open waters. Marine GPS also include fish finders and depth sounders, which help locate fish schools and determine water depth. Popular brands of marine GPS include Garmin, Raymarine, and Lowrance.

Specifications and maintenance of GPS in China

Various factors affect the specifications of GPS in China technology. This includes the GPS accuracy, availability, receiver, and system performance.

Chinese GPS uses satellites to give users accurate location information. The satellites broadcast messages with information about their status and position. This helps the GPS receiver know the satellite's location and the signal's delay. The time difference shows how far the satellite is from the receiver.

The maintenance of GPS in China is divided into three parts: satellite system maintenance, ground control station maintenance, and user equipment maintenance.

• Satellite system maintenance: The BeiDou satellite system is responsible for maintaining the satellites in orbit. This includes checking their health, tracking their position and orbit, monitoring their performance, and adjusting their satellite clock and signal.
• Ground control station maintenance: Ground control stations are responsible for the satellite system's orbit and time. The stations are responsible for measuring and controlling the satellites' orbits, tracking their signals, and monitoring their systems. The data is used to ensure the satellites' accuracy and reliability.
• User equipment maintenance: The user equipment is the interface between the users and the BeiDou system. The user equipment must be maintained to ensure the system's accuracy. This includes updating the software, calibrating the hardware, and ensuring the signal quality and timing stability.

Regular maintenance of the satellite, ground control station, and user equipment is essential to ensure the BeiDou system's accuracy, reliability, and continuity. The maintenance activities are performed by specialized organizations and institutions.

How to Choose GPS in China

Choosing the right GPS in China depends on various factors. Here are some of them:

• Readability

  The screen on the Chinese GPS needs to be large enough and bright enough so that drivers can easily read the directions while driving. A display that is too small could be hard to see.

• Battery Life

  Long battery life is important for handheld or portable GPS devices to last through the whole trip without needing to be recharged.

• Durability

  For outdoor use, it is good if the GPS device is strong, waterproof, and able to handle different weather conditions. This makes it last longer in tough situations.

• Voice Directions

  Having voice instructions is useful so that users can hear the directions while keeping their eyes on the road. It is safer than constantly looking at the screen.

• Size and Mounting Options

  When selecting a GPS, consider the size and mounting options. This is important for in-car GPS. The device should be of appropriate size and have flexible mounting options.

• Price

  Price is an important consideration when choosing GPS in China. There are affordable options available as well as high-end devices with advanced features. Determine the budget and choose a GPS that meets the requirements within that budget.

How to DIY and Replace GPS in China

Most handheld GPS devices have a simple interface that allows users to update the software easily. Those with GPS integrated into their car's dashboard may need professional help to get the maps updated. Here are the DIY steps to replace GPS in China.

• Connect to a Computer

  Connect the GPS device to a computer using a USB cable. The computer will have the latest maps and can transfer them to the GPS device.

• Open GPS Software

  Open the GPS software on the computer. This is the program that manages the GPS maps and data.

• Check for Updates

  Look for an option that says "Check for Updates" or "Update Maps." This will tell the software to see if there are new maps available.

• Download Maps

  If there are new maps, the software will download them from the Internet. This may take some time, depending on the map size and Internet speed.

• Transfer Maps

  Once downloaded, the software will transfer the maps to the handheld GPS. Now, the device has the latest maps for navigation.

Q and A

Q1: What is the most accurate GPS in China?
