GPS wouldn't make much sense. Radio waves at 1.5 GHz don't make it more than a cm or two below the surface. If you have seen a GPS unit reporting a position at greater depth (or a kilometer into a long tunnel with a few hundred meters of rock above your head), it is provided by an accelerometer/gyro, tracking the relative movements from the last known position. I am impressed by the precision of these mechanisms, but they do drift over time, and they are not GPS. Of course they might have a GPS, but it would be of any use only when the Titan is surfacing.
For communication electronics: I guess that very long wave radio signals, maybe as low as 80-100 kHz (a wavelength of roughly 3 km) could break through 3800 m of water, given sufficient transmitter power. That power might be available at a support ship, signaling to Titan. I question whether it would be available in Titan for signaling to the surface. At these wavelengths, very little bandwidth is available; you might easily disturb other essential communications. Long wave radio signals go a long way! Of course they might have communication electronics for 'normal' communication frequencies, but this would be of any use only when the Titan is surfacing.
Neither GPS nor communication electronics (with a possible exception for extremely long wave) would be of any help a few thousand meters below the surface, where we may assume that they are located now.

That thing would float just under the surface. It's white. It will be a needle in a haystack. At that point electronic comms would literally be a lifesaver.
We also don't know whether it is still submerged. There were supposedly systems which would allow it to float up if something happens. For all we know, those could have worked and those people have been bobbing just below the surface, 1 foot away from fresh air, because noone knows where they are and they have no way of signaling.
Of course it would not matter, 4000m below. The point is that there are so many scenarios where those people are f***ed because every possible 'what if' was ignored.

One might suppose as well that if the controller failed completely, even blew up, that it would not stop the communications from working.

In the worst-case scenario, (which I sincerely pray does not happen), if the vehicle gets crushed under the extremely high water pressure down there, likely that it will become something of the size of a couple of footballs, making the detection and recovery extremely difficult, isn't it?

No. Neither the titanium bow nor the carbon fiber hull will be pancaked to that extend.

Fascinating animation!
But some of us are spoiled ... If I jump into a boat here in Trondheim, Norway, and steer out towards the open sea, I will floating on almost 600 meters of water before I am out of the Trondheim Fjord. Norway's longest fjord, the Sognefjord, is also the deepest, slightly more than 1300 m.
So I am more surprised by how shallow many seas are. I sort of expect 3-400 m to be the "normal" 
Then a question to anyone who might know:
The animation shows "SAPEI (Deepest Submarine cable) β 1600 m". To me, it looks difficult to find a path for a trans-Atlantic cable (and no simpler for a trans-Pacific one!) that won't cross any depth exceeding 1600 m. So, are all those trans-ocean cables simply floating in free water at some depth? At which depths? How do they keep it stable? For how long stretches can a cable be free-floating like this? Unless the cable has a specific weight (i.e. density) very close to the surrounding water, there must be a tremendous drag in the cable on both sides! How is this handled? And what happens if a giant hungry shark takes a healthy bite of the cable, is it possible to pick up the pieces from both sides and tape them together again, or would it be just as simple to lay an all new cable? (Well, I do assume that the cable is reinforced to handle attacks from small sharks )
Feel free to provide a link to a web site that answers this kind of questions!

They're probably running out of oxygen today.
Really sounds like one of the worst ways to go, waiting to suffocate in a tin can on the bottom of the ocean

It had more to do the fact he wanted to hire inexperienced people to man the vessel. That's the price of making a political statement rather than a genuine one. That dude still could've marketed to a younger crowd if he wanted to sell his soul to propaganda, while still having experienced people run the thing.

Also, not to be a downer. But, I come from a family of scuba divers. I'm not a nautical engineer, but I can testify that if something went wrong structurally to the vessel, they're dead. Zero chance of survival at that depth. There are a thousand reasons why, not the least of which is the pressure. That's over 363 atmospheres, something the human body cannot withstand.
To give context, an aquatic atmosphere is measured by the difference in air pressure at sea level when compared to space. Underwater however, that same delta only takes 33 feet. So in essence, that depth is over 363 times the amount of pressure you feel at sea level. If the vessel was poorly constructed and was damaged, they or a piece of crappy equipment would've been instantly crushed by the pressure. They would not have time to ascend. They would be crushed instantly.

An open water diver is typically allowed to only go down 100-120 feet tops. And that's for experienced divers. Beginners should not ever start with that depth. The human body can withstand more pressure (not the depth of the Titanic though) and in fact you be nitrox certified to go down to 200 feet. That's for very experienced divers. If you don't know what you're doing and ascend too fast, your lungs will explode for instance - no biggy. You fly the next day, you have problems, etc.
Point being, at 200 feet you need to be trained to handle that amount of pressure. And that's only like 6 atmospheres. There's no way a human could survive at 363 atmospheres.

Why is that frightening? It's just a device that converts hand or finger movements into digital signals, and a well developed reliable one too. Inside the sub it will be operating in an environment not unlike your home, in terms of temperature, humidity, pressure etc. And no dogs to trample on it.
It's what those digital signals control that is important.
