Digital avalanche transceiver with LED display beacon transmits 2.275 KHZ 2275 HZ 457 khz was used by hijackers to blindly fly the airplane MH370 from Malaysia #psychic #prediction

i was looking at the ways to fly without the usual stuff and found out this might work.

Passive visual sensing
Inside the consortium, there is experience in processing images for keypoint-based localization and mapping in unstructured environments also in presence of rather homogeneous surfaces. Thus, at least monocular cameras are foreseen on all the platforms.

the idea girl says
the kept going down really LOW in the flight pattern, maybe this is why? they used camera’s on the plane to see where they were going… instead of radar screens.
remember the pilot was very experienced in using toy airplane models and a simulator…

This is the maiden voyage of the my second attempt at building a rc plane from scratch. It was a little windy day for flying, especilally considering that it is my first true flight.
About the plane. The Airframe made primarily from two peices of $7.00 foam core (or foam board), a carbon fibre spar, two wood dowels, hotglue, two thin peices of plywood and packing tape. Motor mount is made from a 150mmx45mm peice of 3003 aluminum. It is powered by 3300mah Turnigy 4cell 30c Lipo, a 60-70amp hobby king ESC, driving a Turnigy D3542/4 1450kv 130g motor, prop is an apc 10×5.
A stereo camera attached to the end-effector of the “Donkey” will enable precise visual servoing. The FWUAV will make use of its inherently large baseline by carrying cameras on the wingtips (3 meters baseline). Furthermore, we plan to equip at the FWUAV and possibly other platforms with thermal cameras, providing vision-based navigation even in the dark, and also to obtain a powerful tool for people localization likewise.
Early avalanche beacons transmitted at 2.275 kHz (2275 Hz). In 1986, the international frequency standard of 457 kHz was adopted, and this remains the standard today.Many companies manufacture beacons that comply with this standard.
Frequencies and Technical Information
The W-Link frequency in use varies based on geographical location. Currently the frequencies are 869.8 MHz in Region A and 916-926 MHz in Region B. Region A consists of the majority of the European Union, Sweden, Norway, Greenland, Iceland, and other countries in that vicinity. Region B consists of Canada and the United States. W-Link frequencies are not permitted for use in Russia, China, India, Australia, New Zealand, Japan, and other various countries in Asia and Eastern Europe. Users may disable W-Link capabilities on their individual beacon when traveling to these countries, although switching between Regions B and A may require servicing by an authorized retailer.
Digital transceivers take the strength of the signal and the emitted dipole flux pattern and compute distance and direction to the buried transceiver. In order to calculate the emitted dipole flux pattern, a digital transceiver must have at least two antennas, although most modern transceivers have three. The digital beacons will then indicate the direction to the victim’s beacon as an arrow on the display, and provide audio cues such as varying pitch or frequency. Most low- to mid-range beacons have a segmented arrow capable of pointing in five to eight forward directions only, displaying a ‘U-Turn’ indicator if the user is traveling away from the victim. Higher end beacons such as the Mammut® Pulse Barryvox and Arva® Link are equipped with a digital compass and free-flowing arrow, facilitating more exact direction finding, even rotating to maintain direction between pulses of the transmitting beacon (a feature that is impossible without a digital compass or sophisticated accelerometer). In addition, many higher end beacons can point to victims 360°, including behind the user if the user is moving in the wrong direction. Many digital beacons are also capable of being used in analog mode for more advanced rescuers, or to enhance reception range.
