gps gps static positioning instrument

There are five common gps static positioning instruments: "GPS dual-frequency static measuring instrument", "GPS single-frequency static measuring instrument", "RTK system", "static differential measuring instrument" and "GNSS data collector" : 1. GPS dual-frequency static measuring instrument, a high-precision GPS positioning instrument with higher measurement accuracy and faster data collection speed; 2. GPS single-frequency static measuring instrument, which can provide higher positioning accuracy; 3. , RTK system, which combines GPS measurement and differential correction technology, can achieve real-time high-precision positioning and so on.

# Operating system for this tutorial: Windows 10 system, Dell G3 computer.

GPS (Global Positioning System) static positioning instrument is a device used for precise measurement and positioning. It is mainly used in surveying, geological exploration, land surveying, construction engineering and other fields. The following are some common GPS static positioning instruments:

  1. GPS dual-frequency static measuring instrument:

    This is a high-precision GPS positioning instrument that uses dual frequency The receiver receives satellite signals and calculates position coordinates by observing multiple satellites simultaneously. Such instruments typically have higher measurement accuracy and faster data acquisition speeds.

  2. GPS single-frequency static measuring instrument:

    This instrument uses a single-frequency receiver for measurement. Although the relative accuracy may not be as good as dual-frequency instruments, it can still provide better High positioning accuracy.

  3. RTK (real-time dynamic differential) system:

    The RTK system combines GPS measurement and differential correction technology to achieve real-time high-precision positioning. It usually consists of a base station and one or more mobile stations. The base station receives GPS signals and performs differential calculations, and then transmits correction signals to the mobile stations to achieve high-precision real-time positioning.

  4. Static differential measuring instrument:

    This instrument performs differential calculations by receiving signals from a reference station with a known position, thereby improving positioning accuracy. It is suitable for applications that require higher accuracy but do not require real-time positioning.

  5. GNSS data collector:

    This device is specially used to collect and record raw observation data from GPS or other Global Navigation Satellite Systems (GNSS). It is often used in conjunction with subsequent data processing software to achieve precise measurement and positioning.

It should be noted that the selection of GPS static positioning instruments should be based on specific application requirements and budget constraints. Different instruments have different capabilities, performance and accuracy levels, so their technical specifications and performance indicators need to be carefully evaluated when selecting.

What is the difference between gps and gnss What is the difference between gps and gnss Feb 02, 2023 pm 03:06 PM

Difference: 1. Different definitions. GPS refers to the Global Positioning System, which is a high-precision radio navigation positioning system based on aerial satellites; while GNSS refers to the Global Navigation Satellite System, which uses the pseudorange, ephemeris, and satellite information of a group of satellites. Observations such as launch time. 2. Different applications. GPS is mainly used for navigation and positioning. It has attracted many users with its high accuracy, all-weather, global coverage, convenience and flexibility; GNSS can provide users with all-weather 3D coordinates at any location on the earth's surface or near-earth space. and speed and time information space-based radio navigation and positioning systems.
