On the Role of HAP as Support System to Galileo Regional/Local Components

Fabio Dovis, Letizia Lo Presti and Paolo Mulassano

Abstract:	The possibility to provide users with a large number of navigation-related services has been a driving force to increase the Global Navigation Satellite Systems accuracy, availability, reliability, integrity requirements and a stimulus for their integration with the world of personal communications. With this aim, several support systems both terrestrial and satellite based have been implemented; under the boost of the Galileo deployment and of the GPS modernization, new evolutions of such augmentation systems are being studied and designed . In this paper we present the latest results of a research activity introduced in [1] and [2], addressing the design of a novel GNSS augmentation system based on the use of High Altitude Platform (HAP) [4]. After a brief introduction on the Stratolite concept, we the integration with Galileo Local Element (GLE) architecture is discussed and a case study where the Stratolite is employed as support infrastructure using EGNOS, is discussed.
