Abstract

A system to provide to different users with information about position coordinates of remote mobile vehicles or individuals (mobile agent) guarantying that each particular position data, as it is provided to the user, is within certain error boundaries. The system is composed by a number of mobile units (MU) installed at the mobile agents and a Central Platform (CP). The MU consists of a GPS/SBAS and/or a Galileo navigation receiver that includes specific autonomous integrity algorithms and a transceiver to transmit GPS/SBAS and/or Galileo derived data to the CP. The CP receives data from MU and enhances position estimation and position integrity. Integrity is guaranteed by the use of a GNSS Integrity service (either provided by SBAS or Galileo) and specific autonomous integrity algorithms that ensure the position integrity in non-controlled environments. The CP provides access to MUs position data to multiple Users via Internet or dedicated telecommunications links. Integrity guarantee of provided position data allows the Users to employ provided position data for legal or commercial purposes where auditability and traceability of position error is required. Besides the support of multiple Users on a single MU allows for the provision of different types of position based services based on the same mobile device.
