Combined ADS-B and GNSS Indoor Localization

Satellite-based localization systems do not work well indoors. Signals sent by aircraft in the ADS-B protocol however can be used for indoor localization. We propose improvements to the multilateration using ADS-B messages and then combine ADS-B multilateration with satellite-based localization. Even in situations where not enough satellites are available to estimate a position, the addition of AD...
