This video needs some corrections. At 1:30 he says "...maintained by the United States Air Force". The GPS constellation is both maintained and operated by the United States Air Force. Kinda Nit-picking? Well lets go on... At 1:45 he mentions "27 GPS satellites" (space vehicles); there are actually more than that in orbit, and the constellation performance requirements are based on a constellation of 24 available space vehicles, not 27. At 1:57 he says ..."wherever you're standing each satellite will pass over your head twice in a day", and at 2:30 he draws a depiction of GPS orbits and mentions "orbital planes". One of the planes he draws is a polar orbit. Be advised that the inclination for ALL of the GPS space vehicle orbits is the same, and it is 55 degrees. Importantly: between 55 deg north latitude and the north pole and 55 deg south latitude and the south pole NO GPS space vehicles ever pass overhead. Thus precision of GPS solutions for users in those latitudes degrades as they get closer to each respective pole. All you have to do is Google "GPS orbit inclination" to confirm that. Given 3+ strikes in less than 3 minutes, and you can Google to get more reliable information: I'm not wasting any more time watching this.

this topic on land surveying is phenomenal by the lecturer who indeed understand land surveying and what it takes be one. i wish to have him as friend so things will be in other in surveying. but want him to tell me is it possible to plotts coordinate on Google earth pro. please keep me posted on lands surveying.

Yes, this is a good general overview of GPS fundamentals but the explanation of how RTK works is wrong. At around 48:00, he mentions that the base station transmits a "delta" so the rover can correct its coordinates. Actually, the base station transmits its raw carrier phase observations to the rover so it can process the relative vector from the base by double differencing.

The base position is not a known position at all. It's.just a constant position that can be used to process a relative position from the base to the rover.. 47:07.

i like how the students asked him questions to clarify how a gps reciever would know when the signal started in order to find the difference between the time when it was sent and the time it was recieved and he just kept pointing at his dumbass explanation on the board that displayed literally zero math and expected everyone to just nod their heads as if it was a sufficient explanation....

Someone probably already made this comment, but cell phones do not get additional position data from a “WiFi” signal, they get that information from a cellular signal. They try to refine your position by determining your distance from the cellular tower you are connected to.

At 33:57 he states that (10123, 459344) shows 10,123 meters north and not east. Is this not (East, North) just like an (x,y)? He states the Northing first, and the Easting second.

Thank you very much for publishing this information. I am using Pix4D in conjunction with aerial photos taken with my drone to produce orthomosaics. I understand the process, but in the three courses I have taken, very little explanation is provided on how to obtain the GPS data.
