The speed sensor could be calibrated from the GPS when there is a signal. This is already used for some upmarket in-car GPS navigation systems. GPS doesn't give an accurate speed on gradiants. If you're the amazing engineer you make out you'll know why won't ...

... patients. Doctors at 25 UK and US hospitals will study 1,500 survivors to see if people with no heartbeat or brain activity can have "out of body" experiences. Some people report seeing a tunnel or bright light, others recall looking down from the ceiling at medical staff. You're either dead or you're alive, you can't just be sort of dead. IMV, people that experience NDEs ...

... is no such thing as a perfect filter. But what you possibly fail to understand is that a carrier signal at 900MHz, or 400MHz for that matter is about as likely to interfere with VOR at 118MHz as an electron tunnelling to Mars. I am not ruling out that interference comes from the PED but if you read the start of this thread, you will see that I postulate that this interference does *not* come wireless transmissions, either GSM at ...

... services to Moorgate before electrification, and Kentish town afterwards, and would be useless for freight unless this was 1930-odd and freight was still running to St Pancras goods or via the snow Hill tunnel :) Quail does indicate that there's a freight terminal just outside St Pancras: Churchyard Terminal, used for cement and similar. I have no idea if that predates the rebuild, was temporary during the rebuild, or still ...
