A 2.5-km maximum range laser rangefinder, a GPS and a digital magnetic compass are included.

We put the 350 magnetic compasses also into the strict two-dimensional rectangle lattice, and found no ordered domains just as was predicted theoretically (Fig.

Pedagogic demonstration of spontaneously broken symmetry by magnetic compasses

Putting aside the legality of operating an aircraft with known equipment deficiencies, the point is we can reasonably expect to complete a half-hour flight with a defective fuel gauge if we visually verify sufficient fuel is in the tank, or use the directional gyro--perhaps in concert with a panel-mounted GPS--instead of the magnetic compass to find a nearby airport to which we've flown many times before and with which we're very familiar.

Known deficiency: did problems with the airplane's quantity indication system make a fuel-exhaustion accident inevitable?

A 2.5 km laser rangefinder is included, along with a digital magnetic compass. The Jim-MR was recently adopted for the Felin soldier programme.

Forward observer gear gets target right: the ever-present need to engage targets on the so-called 24-hour battlefield is the major driver behind the growth of the forward observer system market. Not only must today's forward observer be able to detect targets in all weathers and during the day or night, but they must report the position of these targets to artillery units, other troops or aircraft

It was paid for by the society.: Just what IS a binnacle?:The binnacle is the stand for the magnetic compass on board a ship.

BATTLE TO KEEP SCOTT'S BINNACLE

If a single point in time can be picked as the moment when Europe first took the road that was to lead to world dominion, it was the moment when Europeans heard of the magnetic compass and put it to use.

Magnetic compasses

"Magnetosomes align with one another to form a chain inside the bacteria and work like a magnetic compass," said study leader, Dr Adrian Muxworthy, from Imperial's Department of Earth Science and Engineering.

Bacteria's tiny magnetic crystals are a compass, say researchers

Then, as I was looking at the mag compass, the controller asked ATC's equivalent of, "Where are you going?" I answered, "Venice?" As I noted the same indications from both my magnetic compass and my trusty handheld GPS, he asked, "Then why are you heading west?"

Everyday partial panel: flying needle-ball-airspeed when everything is working and without covering the gyros will help you stay sharp when you need to be

It contains a tilt-compensated magnetic compass, electronic pedometer and barometric altimeter to provide a continuous deduced position.

To see how mole rats actually use that innate magnetic compass, Kimchi and her colleagues tested the animals in different networks of tubes, one shaped like a wheel with eight spokes and another assembled as a grid.

This meant that a gyroscope, maintaining its axial orientation, could be used as a steady indicator of true north, substituting for, and better than, the magnetic compass that had been in use for some six centuries.
