Evil Waveforms (EWF) are non-nominal distortions that can be observed on satellite signals and cause additional bias on the estimated user position. A Threat Model (TM) has been proposed by ICAO for GPS L1 C/A to describe the possible distortions tha

The consequences of GPS L1 C/A signal distortions due to payload failure on a civil aviation GPS user has received a lot of attention in the late 1990’s and early 2000 following the occurrence of a first such event in 1993. The result of the corres

International audience; In order to improve the potential accuracy of our indoor positioning system, previously based on repeaters, we have moved for a few years to the so called "repealite system". The main idea is to be able to carry out carrier ph
