Differential correction is a technique used to improve the accuracy of satellite-based positioning systems by correcting signal errors through the use of reference stations with known locations. This method significantly enhances the precision of GPS data, making it essential for applications requiring high accuracy, such as surveying and navigation.
Real-time Kinematic Positioning (RTK) is a satellite navigation technique used to enhance the precision of position data derived from satellite-based positioning systems, such as GPS, by using a fixed reference station to provide real-time corrections. This method allows for centimeter-level accuracy, making it crucial for applications in surveying, agriculture, and autonomous vehicle navigation.
Satellite clock error refers to the discrepancies in the timekeeping of the atomic clocks onboard GPS satellites, which can lead to inaccuracies in the positioning data they provide. Correcting these errors is crucial for ensuring the precision and reliability of satellite-based navigation systems.
GNSS Correction Data enhances the accuracy of Global Navigation Satellite Systems by providing additional information to correct errors caused by atmospheric conditions, satellite clock inaccuracies, and other factors. This data is crucial for applications requiring high precision, such as surveying, autonomous vehicles, and precision agriculture.
A reference station is a fixed location equipped with instruments to provide precise data for correcting and improving the accuracy of measurements taken by mobile units, such as GPS receivers. It serves as a known reference point to enhance positioning accuracy through differential corrections, crucial for applications requiring high precision like surveying and mapping.
