It is impossible to determine location with just radar, sonar or a compass. Radar and sonar just tell you there is something, or nothing, in front of you. A compass just provides a bearing relative to the Earth's magnetic field. To determine a location you also geographic data, i.e. a map of some sort. -- penninojim@yahoo.com

Pilot? Old situation, lost, no GPS, no clue listen with directional antenna for 2 known radio stations Get the angle between those, https://en.wikipedia.org/wiki/Radio_navigation In The Same Way you can listen to ultrasound transmissions underwater to determine you position relative to it. And bats (the animals that YouAsh press-incident tramp had Faulty use to kill millions with COVID) even locate and catch small moving insects using ultrasound for navigation. All in 3D and all in motion. They can find their home too, and communicate with each other using that same ultrasound. Every 'location' has it own ultrasound 'sound' (spectrum), like you can hear with normal ears the sound of waves crashing on a beach. The brain (located for humans between the 2 ears) have this thing called 'memory' that creates a map of where you were, communication and DNA also passes it on the the next generation of animals so they 'naturally', know where to go Small; fish, whales, what not. There is a lot more to it.

You are shifting the issue. FYI birds even find back and use their own nest from the previous stay. Fish seem to find locations too for putting their eggs, same place they were born. Once near the coast they will go there. Sometiese one gets confused, there recently was some whale in Germany that got up a river, people tried to bring it back to the ocean to save it, they managed to do that, but it died a bit later,

Do you think insults are rational discussion? Salmon hatch and float down a stream out to sea. Years later, from thousands of miles away, they find the very place that they were born in, within meters, to lay eggs for the next generation. What electronics are you designing lately?

Salmon return with uncanny precision to spawn in the exact same freshwater location, often within meters or even yards of the specific gravel nest (called a redd) where they hatched. NOAA Note that they return to a particular type of gravel area. During their long-distance migration across hundreds or thousands of miles of open ocean, they use the Earth's magnetic field as a compass to guide themselves back to the correct general coastal area and river mouth. USGS Salmon use an acute sense of smell (olfaction) to recognize the unique chemical signature and scent of their natal stream, which they imprinted on as juveniles before heading to the ocean.

It wouldn't surprise me if they used e-fields to navigate too. I've been talking to people recently about using e-fields to communicate underwater. Sheet resistors, essentially.

They do not use those names, the map in their brain is so each place has its own sound, reflection signature to put it simple. They also communicate with each other and use memory. Different beaches, rocky coasts, human infested places, different depth, different temperatures, different speed and direction of currents, all places have their own acoustic signature. Imagine music, acoustics. And taste of the water, probably many more factors, friends they know, relations with other animals There is a lot more to it.

Humans are basically also animals. They have figured out a bit more stuff to help them . Also to destroy them. 'Animals' do the same thing as humans, fighting, making war, use things as tools. Eat other animals.. Animals also communicate with each other. We are still working on understanding their languages,

Birds on the other hand -- I think it were crows -- have no trouble un- derstanding traffic lights. They drop a peanut on the ground, and then wait for red light to pick up the edible core.
