Abstract :
One of the most stringent requirements to a multilateration (MLAT) system is very high accuracy of target (emitter) localisation. In view of this, the potential accuracy of emitter localisation (PAEL) based on Cramer-Rao inequality is important to use. Its dependence on system geometry and time of arrival (TOA) measurement accuracy allows choosing reasonable system geometry and requirements for TOA measurements. PAEL for MLAT systems and wide area MLAT (WAM) systems with different geometry is considered including systems developed for the Marco Polo airport in Venice, Italy (as an example). The possibility of velocity determination using PAEL for landing and taking off aircrafts is also discussed.
