Multilateration, or hyperbolic positioning, is the process of locating an object based on the Time Difference of Arrival (TDOA) of a signal emitted from that object to three or more sensors. When a signal is transmitted from an object, it will be received by two spacially separate sensors at different times. The time difference is then used to calculate the objects position. By using three or more sensors, a complete position analysis can be attained by determining the intersection point of the three or more hyperbola formed by the TDOA from each sensor.
There is general agreement that Automatic Dependent Surveillance – Broadcast (ADS-B) will play a significant role at the core of future civil aviation surveillance infrastructure.
Extended ADS (ADS-X) refers to the integration of multilateration techniques into an ADS-B surveillance infrastructure to mitigate the equipage, validation and backup issues surrounding ADS-B and to enable a faster, more comprehensive and more cost-effective ADS-B implementation.
