New Navigation System for the US Army to backstop GPS.

So its a more accurate INS...

US Army approves production of vehicle-mounted GPS alternative

The Mounted Assured Positioning, Navigation and Timing system will provide forces the ability to operate in GPS-denied environments.

Likely uses fluxgate compasses and inertia navigation, coupled with abilty to update it with fixes and might also triangulate with other nodes. The Britis used something similar before GPS

ADATS had a similar system in the late 1980s. It was accurate(ish).

I can imagine that modern stuff is way better, with no moving parts.

The history of inertial guidance dates back centuries ago, but the modern developments started in the 1920s with Prof. Robert Goddard.

Don't worry, today's US military can rely on GLONASS.

it is interesting that INS is a required component on GPS approaches that thread the needle into very tight canyons and other hard to reach places. These approaches require 2 channels INS as the primary navigation system with GPS required to keep the INS updated.

The LINAPS (Laser Inertial Navigation Artillery Pointing System) from Leonardo has been in use by British and Canadian artillery and several other countries since early part of the century. It was purchased by Canada on a UOR in 2006 and installed on our M777s in the field in Afghanistan in 2007 as the Digital Gun Management System. Primary positioning comes from GPS backed up by an inertial navigation unit in the case of GPS unavailability. It was subsequently acquired as an in-service component for all of our M777s as part of the Light Weight Towed Howitzer project.

Map and compass not good enough for you eh??

I had a pretty good track record as a GPO and FOO with just a map and a compass . . . but then I wasn't routinely calling 155 rounds down on Danger Close missions within 80 metres of my own troops. These days I'd take all the tech aides that I can get my hands on.

Target location error of like 300 m so no. Nothing funnier than being told, yeah it’s super accurate it’s 10 figure! Only to have to explain accuracy vs precision.

Well I was going to suggest we all march up and down the square…
