What is GPS?

The Global Positioning System (GPS) is a high-precision radio navigation system based on artificial Earth satellites that provide the accurate geographic location, speed, and time information anywhere in the world and in near-Earth space.

GPS Features

GPS is currently the most successful satellite positioning system in use and is regarded as a milestone in human positioning technology. In summary, the system has the following features.

(1) Global, all-weather continuous navigation and positioning capability

GPS can provide continuous, all-weather navigation and positioning capability for all types of users at any location in the world or in near-Earth space, without the user having to transmit signals, thus meeting the needs of multiple users.

(2) Real-time navigation, high positioning accuracy, and short observation time

When using GPS positioning, position data can be obtained several times within 1s. This near-real-time navigation capability is of great significance to highly dynamic users and can provide users with continuous three-dimensional position, three-dimensional velocity, and precise time information.

The current real-time positioning accuracy using C/A codes is 20-50m, velocity accuracy is 0.1m/s, with special processing up to 0.005m/s, and relative positioning accuracy is up to millimeter level.

With the continuous improvement of the GPS system and the continuous updating of the software, the relative static positioning within 20km now only takes 15-20min.

When each mobile station is within 15km from the reference station, the observation time of the mobile station only takes 1-2min, and then it can be positioned at any time, and the observation of each station only takes a few seconds.

(3) No need for station visibility

GPS measurement only requires the open sky over the stations and does not require the stations to see each other, so it can save a lot of the cost of mark-making (generally 30% or 50% of the total cost of mark-making).

As there is no need for inter-site visibility, the location of points can be as sparse or as dense as required, which makes the selection of points very flexible and eliminates the need for transfer points and transition points in classical surveys.

(4) Provide global unified three-dimensional geocentric coordinates

GPS measurement can accurately determine the plane position of the survey station and the geodetic elevation at the same time. At present, the GPS level can meet the accuracy of the fourth-class level measurement.

In addition, GPS positioning is calculated in the global unified WGS-84 coordinate system, so the measurement results of different locations around the world are interrelated.

(5) Easy operation of the instrument

With the continuous improvement of GPS receivers, GPS measurements are becoming more and more automated. The surveyor only needs to set up the instrument, connect the cable, measure the antenna height and monitor the working status of the instrument.

Other observation work, such as satellite caching, tracking observation, and recording, is automatically completed by the instrument, and at the end of the measurement, it is only necessary to turn off the power and put away the receiver to complete the field data collection task.

If a long period of continuous observation is required at a station, the collected data can also be transmitted to a data processing center by data communication to achieve fully automated data acquisition and processing.

In addition, the size of the receiver is also getting smaller and lighter, which greatly reduces the labor intensity of the measurement author and makes field work easier.

(6) Strong anti-jamming ability and good confidentiality

GPS uses spread-spectrum technology and pseudo-code technology, the user only needs to receive the GPS signal, will not transmit the signal itself, and will not be interfered with by other external signal sources.

(7) Multiple functions and wide application

GPS is a dual-use system for military and civilian use, and its application range is very wide. Specific application examples include car navigation and traffic management, patrol vehicle management, road engineering, personal positioning, navigators, etc.
