OTDOA — This method uses the measured timing of downlink signals received from multiple eNBs to locate the user device in relation to neighboring eNBs. In dense urban and indoor environments, OTDOA can be used to supplement AGPS, provided the user device can detect position reference signals (PRS) from three or more eNBs.
This page compares GPS vs U-TDOA and mentions difference between GPS and U-TDOA.GPS stands for Global Positioning System and U-TDOA stands for Unlink Time Difference of Arrival.U-TDOA is uplink method similar to downlink OTDOA.

Igor Bisio got his “Laurea” degree at the University of Genoa, Italy in 2002. 10 CM Accurate Ultra-wide Band (UWB) Positioning for Arduino, Python and Raspberry Pi Projects: the Easiest Way. : Performance you can expect from this project:The video below is slightly older. Since, Pozyx has managed to increase the update rate for two-way ranging to 140 hertz and for TDOA to 400 - 1000 hertz. But this is still one of my favorite videos as it… WPI - with Byron Chen, Lead SE for E911/LBS in LTEi, Alcatel-Lucent LTE Observed Time Difference of Arrival (OTDOA) method in the other hand uses the measured timing of downlink signals received from multiple eNBs to locate the UE according to the neighboring eNBs.
This video is focused on a location technology that just about all LTE-enabled mobile devices need to support. Observed time difference of arrival, or OTDOA, OTDOA (Observed Time Difference Of Arrival) is a positioning feature introduced in rel9 E-UTRA (LTE radio). It's a multilateration method in which the User Equipment (UE) measures the time difference between some specific signals from several eNodeBs and reports these time differences to a specific device in the network (the ESMLC).

To further improve results, these methods can be complemented with additional technologies such as self-learning fingerprinting or proximity location. The use of a combination of technologies
OTDOA uses LMUs to calibrate the downlink measurements from neighbor base stations for individual mobile users. If measure-ments from three or more stations are available, a position can be estimated [1]. Considering the similarities between the systems, we can view OTDOA as a …
In the second part of the tutorial details on theoretical and practical issues about fingerprinting approaches, implemented by using the WLAN (or a 5G femtocell), will be provided. Speakers.

As mentioned there are various ways to obtain user position. Some of them utilize trilateration, e.g., Observed Time Difference of Arrival (OTDoA) defined for cellular networks in LTE Positioning Protocol (LPP) [], 802.15.4a ultra wide band (UWB) [], or different implementations of GNSS, e.g., Global Positioning System (GPS) or Galileo [].Other ones, may use triangulation.
The received signal at the UE is modeled by delaying each eNodeB transmission according to the values in sampleDelay, and attenuating the received signal from each eNodeB using the values in radius in conjunction with an implementation of the TR 36.814 [ 1] Urban Macro Line Of Sight (LOS) path loss model. WPI - with Byron Chen, Lead SE for E911/LBS in LTE i, Alcatel-Lucent This script is a simulation for TDOA application with linear and nonlinear estimation algorithms. Communications Surveys & Tutorials the objective, while the CGALIES just asked the cellular operators to cooperate. The consequence was an initiative led by standardization groups, such as 3GPP and 3GPP2, to determine the location of the mobile terminal. In the US, the operators could not fulfill the demands set by the FCC and were
