Scientists improve accuracy by 40% for ground orientation

Two scientists from the University of Alicante (UA) and two other Germans have designed a new method that improves by 40 percent the accuracy of the predictions of the daily values ​​of two of the five ground orientation parameters.

This achievement has been published today by the prestigious online magazine 'Scientific Reports', from the Nature group, and is signed by researchers Santiago Belda and José Manuel Ferrándiz, from the Department of Applied Mathematics of the Polytechnic School of the (UA), and by Robert Heinkelmann and Harald Schuh, from the GFZ center, German research excellence institution of the Earth.

The two parameters studied by these mathematicians are called CPO (in its acronym in English) and the new system allows to reach a year of official predictions with precision, when the current only reach about 40 days.

As explained to Efe Ferrándiz, these values ​​are essential for the proper functioning of the browsers that are usually used, for example, on the mobile phone or on a map of a car, and are part of the 5 parameters of terrestrial orientation (EOP in English) that are used for global positioning.
