It is a pleasure to listen to someone who so clearly loves their subject matter. I personally am not engineering inclined, but I could follow the important points.
Absolutely right. I would always normally say ‘three times ten to the eight metres per second’, m being the SI unit. And for some weird reason I decided that km per second was more convenient and got it wrong. Thanks for noticing!
Yes that’s right. In fact there is so much fascinating detail in GPS that it could easily occupy five lectures, and add another ten if we were look in detail at GNSS. There are a few tutorials on RUclips but several of them are now quite out of date so one has to flick between the tutorial and the GPS website to get the full picture.
I'm just a layman who uses GPS on my phone for OS maps etc. Decided to watch this video as I was bored on Saturday afternoon. I understand with the Chinese GPS its two way, they know where you are! Do you think the uk will ever produce its own GPS system? (I'm welsh) Very interesting, thankyou.

Very interesting talk, Professor Harvey. My understanding is superficial, but I enjoy the enthusiasm in you voice for your subject matter.
Correction for info at 7m 08s - radio waves travel at about 300,000 *kilometres* per second, not metres per second

The thing I find fascinating about GPS is the fact that the satellite clocks have to be offset to account for General and Special relativity.

When I learned that C/A codes are rulers flying at you from space I felt so excited.

More yawningly dull Gresham content. Such a shame considering the depth of talent they have access to.
