But it also needed to know your 2D position on a map as well ... “We define it as adding a [3D dimensional] layer to GPS, which is more precise and resilient,” Pattabiraman said.

Thus, A-GPS will not be possible if there is no communication link. Normally, A-GPS provides 2D position data. The height data (if 3D output is available) will be highly erroneous. The accuracy of ...

Before the advent of GPS, especially at sea, navigation meant finding your position by looking up at ... But even as other companies have tapped 2D and 3D imagery for GPS-free navigation, they ...

Given the laser range measurements, 2D features located on the scan/pixel intersections can be scaled up to 3D points ... filter that uses GPS carrier-phase measurements to estimate velocity and other ...

Of course GPS works anywhere, so your position will be right on the detailed ... You can find locations by searching, and view the terrain in 2D or 3D. The 3D is beautifully rendered, and you ...

Maxar Intelligence announced its new Raptor software designed to help drones navigate without GPS. Raptor works by combining a drone's visuals from its camera with Maxar's 3D topographical data.

AUSTIN, Texas—Because GPS can be spoofed or jammed ... “Raptor provides absolute position estimates by matching what a drone sees to Maxar’s 3D map. These estimates can be fused with inputs ...

A quantum device that can determine its position in three dimensions is more accurate than non-quantum versions. Vehicles could use it to navigate even if GPS stopped working. One way to keep ...
