Not if the only thing you're tracking is pulsars. There aren't that many that the model would have to track. Your pic relates: The system would not have to track all objects. But, it would be helpful so that you don't run into stuff. The speeds required for travel (even within the solar system) could make any collision deadly. zeenews.india.com/news/space/astronaut-finds-bullet-hole-in-iss-solar-panel_845683.html

As of now they don't. Currently, it's too difficult to precisely measure the speed of the pulsars. It's unnecessary too, they're just so far away that even though they're moving thousands of miles an hour, they're relatively fixed points in the sky. Anything we'll be doing anytime soon will most likely use a static model, as it's just too much work to accurately produce a dynamic model. Right now, they seem to have limited themselves to using pulsars that can be approximated as static. In the far distant future, they'll have to use a dynamic model, but the current "static" model is accurate up to 1 km anywhere in the solar system, which is more than sufficient for anything we'll ever use it for.

Here's a link to the paper if you're interested: microcosminc.com/analysis/AAS%2008-054%20XNAV.pdf

"I wonder if they account for the pulsars moving?"
No, when dealing with relativity, scientists certainly don't consider things moving.
The GPS we have now is already heavily accounting for movement on a level too tiny for most people to comprehend, let alone work with.
I'm almost certain that not only are they accounting for it, it's a major factor as to why the pciture says "working on" and not "implemented already and I mean, it wasn't even that hard guys"
#99 - kingpongthedon (05/06/2013) [-]
Nope, they just found pulsars that are moving so slow, they can be approximated as static. You gotta remember, they're so far away, we can barely perceive their movement. It won't affect a triangulation system at all.
#103 - drshkidz (05/06/2013) [-]
I feel like that puts an operational limit on range, lifetime and accuracy and in no way recognize the validity of settling for a design that merely works "pretty damn well all things considered" in favor of "provably accurate to the nearest planck length."
Go figure. Lazy goddamn astrophysicists.
#104 - kingpongthedon (05/06/2013) [-]
It does, but you gotta think of it as an engineer and not a scientist. Engineers are all about taking the easy way out. And frankly, there's just no need to design a system that accurate. Once you're within a km of something, you're probably already using detection devices, like old-fashioned cameras, to do your navigating. And we've only produced one object that has left the solar system. It will be hundreds, if not thousands of years before that kind of system needs to be implemented. Right now, we just don't have the need or technology to implement a dynamic system.
#107 - drshkidz (05/06/2013) [-]
Well, no I got that, I pretty much cotton'd on to it once you pointed out they had just gone ahead and scraped by, then I put it together with the five klick maximum deviation that they had just settled for something workable in a first generation system.
But wonderful clarification anyways. It's kind of easy to forget we haven't really gotten much under our belt in the way of even system-wide travel, y'know? I'm just worried that my grandchildren's grandchildren's etc might end up in some gas giant from using bootleg 21st century positioning algorithms.

This system depends on a working 3d model of the galaxy. Any model of this nature has to include movement.
#100 - kingpongthedon (05/06/2013) [-]
It doesn't account for motion, they just found pulsars that are moving so slow, they can be approximated as static. They're just so far away that any motion they may have has no practical effect on their apparent location.
