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