Performance Analysis of Mobile Station Location Using Hybrid GNSS and Cellular Network Measurements

Pierre-André Farine, Cyril Botteron, Elham Firouzi

Recently, different hybrid GNSS/cellular methods combining GNSS measurements with cellular network measurements have been proposed. These methods are designed to improve the availability (and accuracy) of position determination in situations where few sate ...

Challenging EGNOS in the Swiss Alps

Pierre-Yves Gilliéron

In view of the operational validation of EGNOS, some early tests are being performed with the EGNOS System Test Bed (ESTB). This prototype has been broadcasting an EGNOS-like signal since early 2000. The performance of ESTB is reduced compared to the full ...

Capteurs et algorithmes pour la localisation autonome en mode pédestre

Quentin Ladetto

The challenge of knowing one's position in a precise and reliable way, at any time, with and without reception of satellite signals, represents an area fairly explored for the navigation of vehicles. To widen this service to the pedestrians requires a diff ...
