Talk:True-range multilateration

Broken link?

The link "Efficient Solution and Performance Analysis of 3-D Position Estimation by Trilateration" in the External Links section gives me a 404 error. daviddoria (talk) 14:34, 12 February 2013 (UTC)

As of 30 May 2014 the link points to a file hoster that shows porn when cklicking the download button. The link should probably be removed.--Jmknaup (talk) 11:28, 30 May 2014 (UTC)

http://www.globmaritime.com/technical-articles/marine-navigation/general-concepts/9622-trilateration-traverse-and-vertical-surveying.html link (reference number 3) is dead, someone should replace it with something suitable. Alenrajsp (talk) 12:31, 22 July 2016 (UTC)

Dec. 2018 Edits

I added material to several sections. One intent is to show that trilateration is not just an analytic geometry problem. Real-world navigation and surveillance systems use it as well. Before my edits, the article read like a college freshman calculus homework assignment.

Second comment: GPS is not based on trilateration; it's based on multilateration (as defined by Wikipedia). I deleted that incorrect material.

Third comment: The title trilateration is a poor choice. Perhaps it reflects an academic orientation? This point is better made on the Talk:Multilateration page by the first commentor. Re-titling this article would likely require that the current multilateration article be re-titled as well, and there appears to be little interest in doing that.

As a practicing engineer for decades, I never encountered the term trilateration. (What is DME/DME aircraft navigation: bilateration? trilateration, but not literal?) I'd prefer a title like True Range Multilateration or perhaps Circular Multilateration. Then the current article entitled Multilateration would become something like Pseudo Range Multilateration or Hyperbolic Multilateration. Disambiguation might be needed as well. But a poor title is less desirable.

@NavigationGuy: I would like to thank you for your edits to the article and remembering to include some citations as well. This area is well outside my field of expertise (I only deleted the content on the basis of wiki policy), if you feel a title change is a good idea, may I suggest (after discussion in an appropriate project if one exists), just being bold and doing it. Many thanks and kind regards EvilxFish (talk) 15:28, 13 January 2019 (UTC)

Perhaps to conclude this editing phase you might want to delete the clumsy and no longer applicable picture at the top of the page. As compensation you might also want to add some circular arcs to the other picture used to elucidate the formulas −Woodstone (talk) 05:16, 14 January 2019 (UTC)

Jan. 2019 Edits

For the reasons given above, I changed the page title from Trilateration to True Range Multilateration. Comments welcome. NavigationGuy (talk) 15:16, 15 January 2019 (UTC)

In changing the name, I mistakenly created Category: True Range Multilation by mistake. Sorry. NavigationGuy (talk) 13:53, 18 January 2019 (UTC)

Renaming

Dear @NavigationGuy:, I appreciate all your work in the disambiguation between pseudorange multilateration and true-range multilateration. I just wanted to suggest that we stick to common name policy, thus renaming the present article back to Trilateration -- while also leaving a very clear hatnote saying: This article is about "true-range multilateration"; it should not be confused with pseudorange multilateration. What would you think of this proposal? Thanks for your time. fgnievinski (talk) 19:19, 10 September 2020 (UTC)

@NavigationGuy: I intend to request the article be moved back to its common name (Trilateration), that you had moved without discussion [1]. The generalization to more than three ranges can be easily accommondated by simply inverting the simplification to the special case currently described in the lead. fgnievinski (talk) 20:06, 6 November 2022 (UTC)

I've created a third broad-concept article for trilateration (multilateration). fgnievinski (talk) 05:52, 7 November 2022 (UTC)
