A long-range acoustic side-scan echo-ranging technique has been employed to the east of the Bahama Islands-Blake Plateau area. Towing a hydrophone array at approximately 600 meters and regularly firing deep explosive charges as sound sources yielded ranges of ≤370 km. Ranges were limited by topographic relief and not by the ranging system.

Accuracy of Range-Range and Range-Sum Multilateration Systems
IEEE Transactions on Aerospace and Electronic Systems, 1975A recent paper [1] described a novel procedure for assessing the accuracy of hyperbolic multilateration systems for the case of uncorrelated ranging errors. Basically the procedure reduced the problem of assessing accuracy to that of calculating the moments and products of inertia of a simple mass constellation. This paper derives analogous results for

Precision ranging systems for close-range weapons
Journal of the Institution of Electrical Engineers - Part IIIA: Radiolocation, 1946The paper traces the development of naval close-range radarranging devices from 1939 to 1944, and describes the factors responsible for the successive changes. A simple discussion of the prediction of aircraft future position, including a mathematical analysis of ?rate-aiding?

Proceedings of the 2008 ACM conference on Computer supported cooperative work, 2008
An important challenge in designing ubiquitous computing experiences is negotiating transitions between explicit and implicit interaction, such as how and when to provide users with notifications. While the paradigm of implicit interaction has important benefits, it is also susceptible to difficulties with hidden modes, unexpected action, and ...
