Localization systems such as the Global Positioning System (GPS) are prone to jamming and spoofing. Localization using the Signal-Of-Opportunity (SoOP) gained much attention recently as an alternative to typical localization systems. We consider a general scenario where a receiver deployed on a mobile UAV finds its location based on Time Difference Of Arrival (TDOA) measurements with a number of unsynchronized reference Base Station (BS) receivers using signals from unsynchronized transmitters. The UAV has relative time offsets and clock skews with the BSs. We derive the Cramer-Rao Lower Bound (CRLB) of the UAV location and relative skews. Then, we plot them for Phase Alternating Line (PAL) analog TV transmission as SoOP.eninfo:eu-repo/semantics/openAccessLine-Of-SightLOSNon-GPSReceiver Self-LocalizationSignals Of OpportunitySoopTDOAUAVConference Object15816310.1109/CAMAD59638.2023.10478402N/A0011961003000272-s2.0-85190550974N/A
