The Value of Integrity for GNSS-Based EFC Systems

The main objective for the Global Navigation Satellite System (GNSS) based Electronic Fee Collection (EFC) systems is to obtain its PVT with a certain level of quality, expressed in terms of accuracy, integrity, continuity and availability. The ability to provide efficient toll collect is directly related with availability of integrity at the On-Board Unit. Assuming EGNOS assures a service with a certain defined quality, these systems should take advantage from such assurance. The integrity of positioning refers to the assurance that the system works within specified limits. These limits relate to the maximum error that the system can cope while continuing to exhibit a correct behavior. The “Active Road Management Assisted by Satellite” (ARMAS) project led by Skysoft Portugal, is finishing its third phase of work. The ARMAS project has the objective of demonstrating the feasibility of satellite based technologies in car navigation devices for improving road safety, use in dynamic traffic management and providing a means for generalized and cost-effective road pricing.
