Access to the Galileo signal in a multi-constellation environment is providing benefits and opportunities for businesses, thanks to the enhanced performance and increased accuracy on offer, said the European GNSS Agency (GSA).

Swedish geographical information technology company SCIOR Geomanagement AB uses a variety of technology in its equipment, including drone aerial photography, terrestrial laser scanning, GNSS or combinations of these.

SCIOR, a measurement technology producer, incorporates RTK processing techniques into its approach. The company also uses Galileo-enabled receivers to increase the positioning accuracy of its solutions.

According to the company’s findings, which it presented at the 2019 Intergeo conference in Stuttgart, it has been achieving significantly enhanced performance and other benefits in its day-to-day activities from the use of Galileo-enabled equipment, GSA said.

“Our experience with Galileo has shown an improvement in the density of the constellation of visible satellites, and thus an improvement in the time needed to obtain centimeter-level accuracy,” said Javier Corral, an engineer at SCIOR Geomanagement AB. “From my personal point of view, I would recommend using this constellation in combination with the other existing ones, since it provides you with a better and quicker performance.”

According to GSA, the most significant performance improvements are observed at high latitudes and within forest environments. Even taking into account that better results can be obtained in open spaces, using multi-constellation GNSS with Galileo in the woods is sometimes the only way to obtain a satisfactory performance if there is no reference station close enough. performance will be even better in coming years as the number of Galileo satellites increases to reach full operation capability, allowing users to obtain their desired position accuracy and availability in a shorter period of time, GSA added.
