There are many RTK GNSS Basic Solutions on the market today. So, how do you choose the right one for you? Read this blog to enrich yourself with all information about these solutions.
What is GNSS?
GNSS, or Global Navigation Satellite System, is a satellite-based navigation system that provides positioning, timing, and navigation information to users on the ground. GNSS systems are used in various applications, including surveying, mapping, navigation, and precision agriculture.
An "RTK GNSS Basic Solutions" is the simplest form of GNSS positioning, which uses a single satellite receiver to determine the user's position. This technology is used in surveying and mapping applications to provide more accurate data than what is possible with traditional GPS receivers.
The components of GNSS
GNSS systems are made up of different components, each of which plays a vital role in ensuring the system works correctly. There are three major components of GNSS: space, ground, and user.
- The space segment
The GNSS space segment components are the satellites that transmit the GNSS signals. Each GNSS system has a unique constellation of satellites. GNSS receivers use the GNSS signals to determine their position, velocity, and time. The GNSS space segment components are the satellites that transmit the GNSS signals.
- The control segment
The control segment components of GNSS are the ground stations that monitor and control the satellites. The ground infrastructure includes the satellites, the ground stations, and the control segment. There are three types of ground stations: the master control station, the backup control station, and the monitor station. The master control station is responsible for controlling the satellite constellation.
- The user segment
The user segment components of GNSS are the hardware and software that users need to access GNSS signals. The hardware includes GNSS receivers and antennas, while the software consists of GNSS algorithms and applications. The users are the people or organizations that use GNSS for their applications.
How do GNSS works?
GNSS" is an umbrella term for any satellite navigation system that can provide positioning and timing data for ground, sea, or air vehicles. GNSS systems use a constellation of satellites that transmit signals from space. The signals are then received by GNSS receivers, which use the data to calculate the receiver's position, velocity, and time.
- The signals
GNSS signals are transmitted by a constellation of satellites in medium Earth orbit (MEO), geostationary orbit (GEO), and highly elliptical orbit (HEO). GNSS receivers use the signals to determine their location and time. The most common GNSS signals are GPS signals, GLONASS signals, and Galileo signals. The GNSS signals are used to determine the position, velocity, and time of GNSS receivers.
- The receivers
A GNSS receiver is a device that uses satellite signals to provide its user with accurate positional data. GNSS receivers come in many different shapes and sizes, from hand-held units to vehicle-mounted or even satellite-based systems. GNSS receivers use satellite signals to provide accurate positional information.
- The positioning
Positioning is a term that is used to describe the process of determining the location of something. There are a variety of different methods that can be used to do this, but the most common method is using a Global Navigation Satellite System (GNSS). GNSS is a satellite-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth's surface.
What is RTK GNSS?
If you're looking for greater accuracy in your GNSS measurements, you may want to consider an RTK GNSS system.
Real-time kinematic (RTK) surveying is a satellite surveying technique used to enhance the precision of position data derived from satellite-based positioning systems (global navigation satellite systems, GNSS)
GNSS RTK is a surveying technique that uses the carrier phase of satellite signals to measure the distance between the satellite and the receiver. This technique can achieve sub-centimeter accuracy in the horizontal and vertical dimensions, which is an improvement over the accuracy of traditional surveying techniques.
Advantages of RTK GNSS basic solutions
Real-Time Kinematic (RTK) GNSS systems offer many advantages over traditional surveying methods. GNSS RTK systems are more accurate, efficient, and versatile than traditional surveying methods, making them the ideal choice for a variety of surveying applications.
- Increased accuracy
With the advent of GNSS and the use of more accurate technologies, the demand for GNSS-based positioning is constantly increasing, especially for high-accuracy applications. GNSS-based positioning uses code and/or carrier-based techniques to determine the satellite ranges, which are then used to compute the user’s position.
The introduction of RTK GNSS has made a big impact on the accuracy that can be achieved. This technique is typically used in surveying applications where high levels of accuracy are required, such as in the construction of roads, bridges, and other large infrastructure projects.
- Faster convergence time
GNSS technology has revolutionized surveying, but one of its chief drawbacks has been its slow initial convergence time. GNSS receivers need to "lock on" to four or more satellites to determine their exact position, and this process can often take several minutes.
- Reduces the number of base stations
The need for more precise and reliable positioning information has led to the development of techniques like GNSS Receiver Autonomous Integrity Monitoring (RAIM) and Real-Time Kinematic (RTK). Both of these techniques require a minimum number of GNSS base stations for optimal performance.
The disadvantage of RTK GNSS
The disadvantages of RTK GNSS systems are that they are usually more expensive than other types of GNSS systems and that they require a clear line of sight for the satellites to work properly.
