Unmanned aerial vehicles (UAVs) have made a name for themselves in various industries, most prominently drone mapping with real-time kinetics (RTK). Drones have efficiency and productivity, saving surveying and mapping businesses almost immeasurable amounts of capital.
Moving forward, we are going to make sure there is clarity in the definitions within drone mapping or any other civil engineering studies.
There are many common questions about drone mapping that readers like myself have been left confused about. Eventually, these kinks will be ironed out as people start gaining awareness of organizations within the survey field.
At The Drone Journal we are not experts in any industry, nor do we pay experts to work with us. However, we respect the science of measurement and will fact-check all information with published, scholarly articles.
We have received many questions about GNSS and the aforementioned UAV mapping methods. We will be answering these questions and more throughout the following section.
GNSS is a space-based positioning system consisting of constellations of satellites. GPS is just one type of GNSS, and there are four fully operational GNSS systems in the world: GPS, Chinese Beidu, European Galileo, and Russian Glonass.
GNSS receivers are the core component for satellite positioning. They have an accuracy of 2 to 10 meters and are only possible in outdoor parameters.
A GPS signal travels through the atmosphere, slowing down and perturbing along the way, which leads to errors in the positioning accuracy provided by standard GNSS technology. However, multiple satellite clusters and GNSS receivers can correct this error with 1 cm accuracy.
RTK Technology uses a Base Station and a Rover to improve the accuracy of GNSS positioning to the centimeter level. The accuracy of RTK corrections degrades very quickly beyond 50km from the Base Station.
NTRIP is a language or protocol that distributes RTK corrections over the internet or a local wireless network. It requires a stable internet connection and a high price in some countries.
SSR services use geostationary satellites to transfer GNSS corrections over large areas, and provide wide coverage, reliability, and availability without an internet connection.
GNSS technology provides global coverage for accurate positioning, but RTK technology improves the accuracy to the centimeter level. RTK corrections can be received directly from a Base station within a 50km range, through an IP network, or via SSR services.
Some countries use networks of Base stations with corresponding NTRIP servers, while others use SSR services, which use geostationary satellites to transfer correction models to Rovers. SSR services offer wide coverage, reliability, and availability without the need for an internet connection.
This article summarizes the main points of a comprehensive guide for researching drone mapping and other UAV use cases in geoengineering. It includes information on GNSS technology, RTK technology, and various applications of GNSS technology.
