Signal triangulation software

Triangulation is a pain, illegal, and becoming increasingly obsolete. Please send me info on cell phone pinging software. Although there is a history of domestic violence and sinister actions by my brother in law. Many thanks! Like- I and I airport location then 20 miles down I at another tower location can a cell phone ping off that tower?

I heard it can by-pass airport towers due to blocking by airport for security reasons since Hope its not to late to post a comment on this subject of cellphone ping. Pinging gives you coordinates but usualy the radius of the phone could be up to minimum metres. Try searching for such phone in the rural setlements of South Africa…. What is needed is the KingFisher mobile tracking unit which works like a mini cellphone tower on steroids. Law enforcement agencies in USA can trach a phone within 1 meter radius …in your pocket.

Is there a way to tell if this pinging has been done to my phone? Does this stop when I turn off the phone? Thanks — interesting artical. Ah, how times change. If you get any info about cellphone pinging can you please share.

Steven, Please email me info. I would like to added also sam. Jaycoop05 yahoo. I would like to ask a few questons on this. Pursuit Magazine. Thank You. You should actually only need 3 nodes to do this. The location where these three nodes intersect is where the person resides. Luke Willis Luke Willis 8, 3 3 gold badges 46 46 silver badges 77 77 bronze badges. I tried with 3 nodes first but to make it easier I added a forth. I get the concept just not the bloody math :P thanks for taking time to help me out!

Tiax I fixed a small problem. The calculation for py didn't have a cast to double where it was needed. Also, note that this solution will only work if node1 and node2 have the same y value. I'm working on a solution where this need not be true. Thanks a lot! Will play with it tomorrow : — Tiax.

Works like a charm! If you solve the "problem" with node1 and node2 having the same y value, please let me know! Would be truly great! Tiax Unfortunately, I don't have time to work on implementing it right now, but the algorithm to do so isn't too bad.

Just the pre and post processing of the nodes to make them line up with the specifications and then move them back. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.

Imagine only the two points now. The first part of the above example is true for 3 intersecting circles a 2D world , but satellite signals represent spheres in a 3D world. This is vaguely explained further down in the article. This 4th sphere is shown in the graphical picture, but really does not clearly represent why it is needed.

Three spheres still leave an area of possible locations within the intersecting area. It is hard to represent this area visually. The fourth satellite or sphere pinpoints the exact location without accounting for tranmission or timing errors. See this link to an image for a representation of the limits of 3 satellites.

In addition to WAAS, more satellite signals help narrow down errors. Kindly explain the reason why in satellite positioning observations must be made to a minimum of four satellites.

You need at least 24 satellites in orbit to have have 3 visible satellites at all times for triangulation. Your explanation of trilateration is incorrect. Your email address will not be published.

Find new computing challenges to boost your programming skills or spice up your teaching of computer science. This is done by measuring the time delay that a signal takes to be sent from the satellite to the GPS satnav, and converting this time delay into a distance, Using more advanced multilateration formulas based on a 3D model rather than a 2D model.
