The oceans are too big for the police – and if you just want one example, consider fishing.

The weakness of the open waters of the Earth allows a market of such black to flourish. But in a world that is increasingly monitored by satellites in the Earth's low orbit, technology makes a mission impossible once less impossible.

In 2016 a Global Fishing Watch started with data from all radio routes to transport ships to avoid collisions and map their movements to see fishing in illegal areas. However, ship captains can resist such surveillance simply, turning their beams away – measuring potential that can be removed from the map.

All-Seeing Radar Eyes

But by using new algorithms, a Global Fishing Watch could raise reflections of individual shipping metal bags in the heartlands.

"Radar is good," said Paul Woods, CEO of Fishing Global Watch Technology. "It's going through the clouds, it's working with the nighttime, and it's all the ships, whether it's broadcasting or not."

But radar satellites are scarce and expensive. Sentinel-1, launched in 2014, is a SUV size, weighs two tons, and radar image images are demanding very far.

ICEYE achieved the reductions in size and costs by combining new electronics outside the shelf with intelligent use of trading. Rather than running the power-hunger radar on an ongoing basis and imagining as much as possible, ICEYE only takes selected drawings of areas of interest, making it much more efficient.

ICEYE intends to launch 18 satellites with the first five spaces to be achieved by 2019. By working in teams, this new series with radar equipment will do something that a single satellite could not be replicated the same fan several times a day

"If you can not see where there is iceberg every two days, you have to rely on current predictions," said Pekka Laurila, co-founder of ICEYE. "Or you have to operate an airplane to watch, and that's expensive."

A whole set of satellites means that ICEYE can track berges, or ships, in a very real time. Not only can you see an illegal fishing boat, you can track it and know when it turns on its radio radio.

ICEYE works on a variety of solutions to solve, broadcast and communicate, as well as a novel radar detector that can also find object material.

"This will lead to a generation," said Laurila. "In comparison to television cameras, this will be like a color camera rather than black and white."

"Our cost will be a quantity order and in some cases two size orders are cheaper than the current situation," said Banazadeh. "" This would allow us to provide a seasonal capacity better than three hours worldwide and will place us as the fastest geository information provider. "

Quite, any ship that carries out fishing operations is visible and easily identifiable from a special combination of equipment.

"Previously, this type of data has been available only to information agencies," said Woods. "You'll be able to have a digital post-finger for each individual ship."

Currently Hawkeye 360 ​​carries out mission checks and moves their satellites into a site before the operations. Although Global Fishing Watch can not access the Hawkeye service at once, its success could create a gold rush of small satellites built for track tracking through radio.

Put All Of It Together

But for the new collection of satellites to be useful, Global Watch Fishing will need to merge different data streams into one scene.

"Once you can start placing a radar with other data, such as photography and AIS [radio beacon], you're beginning to have a really nice picture, "said Woods." This is unpleasant a few years ago now becomes inevitable. "

This new generation of low cost observation satellites could also transform agriculture, infrastructure, defense, intelligence and scientific communities, but for policing at sea, there is a new era With nothing to hide policing, Smugglers, traders and pirates based on satellite Do not hide in a prominent appearance, safely within the unusual blue of the sea.

The Wild West of illegal fishing will have to deal with a new sheriff in the town.
