Awesome presentation! Slight correction: GPS receivers do not transmit signals :) The satellites basically say when they are at what time.

[@TonyP9279]

Correct! GPS receivers are receive-only. The GPS receiver derives the time and position from the satellites' almanac data.

[@jorgecorona6783]

GPS receivers are passive. They synchronize the internal clock of the device by downloading first an almanac from one of the satellites. Thats why it took many minutes to initialize a GPS unit on the old days. Now, the almanacs are downloaded via internet on the phones, thats why the required time to initialize a GPS unit is very quick. GPS receiver units never transmit to the satellites.

[@blueskies8834]

Correct, GPS receivers are listening devices, they do not “talk” to satellites.

[@blueskies8834]

Correct, GPS receivers are listening devices, they do not “talk” to satellites.

[@nicholashartzler2205]

This is easy to understand. Consider how much more work it would be for a satellite to actively talk to hundreds of thousands of devices at the same time. It would be like DME equipment that can only handle a small number of devices at the same time (although not precisely, I’m probably comparing an analog to digital signal) it would be overwhelmed. Nice info though about why phones are faster.

You are a very generous and excellent teacher! Wish I had all this info when I was studying for my tests years ago! Only issue I have is your GPS explanation is incorrect. Unlike a transponder, I believe the GPS unit only receives signals, and basically figures out it's exact position from the known location of each satellite at that moment. Keep up the great work and thank you.

[@AeroNerd]

Thanks for your input and you are correct, the explanation I presented for the GPS is incorrect, and I'm working on an update and an apology for the inaccurate information. I'll have an updated video soon. thanks again!

Thanks, very nice summary, exactly what i was looking for. First real RNP approach is planned for Monday :) Just some correction: the GPS receiver does not send anything ever, that would be like DME. It only receives the information of the satellites. WAAS is just one version of SBAS, here in europe we have EGNOS as an example.

[@xNYCMarc]

@8:04 FYI: GPS equipment is receive only. The satellites continuously send out a signal that says "The time is now X and I'm located at such and such a point in my orbital trajectory". When your GPS receiver gets this information from at least 3 satellites at the same time, it can calculate where on the planet it is. The time information is used to determine your altitude since the satellites are at a fixed height. If the signal reaches you quicker, it must mean you are closer to the satellite and the only way you can be closer to it is if you are at a higher altitude, either in the air or driving up a mountain.

[@_Breakdown]

xNYCMarc - - Are u sure...? (1) Isn’t altitude measured from sea level (not satellite orbit)? (2) Wouldn’t the signal have to be reflected back to the satellite?

[@xNYCMarc]

@@_Breakdown Yes I’m sure. The sea has absolutely nothing to do with how GPS measures altitude. Altitude on GPS is determined by how long it takes the signal to reach the receiver. The satellite sends a time stamped signal out. When a receiver receives it, the time will always be later than what the stamp says since it takes time for the signal to travel to where you are. It’s a blink of an eye, but it’s still a measurable amount of time. If it’s “quicker”, then you must be closer to the satellite, meaning you are at a higher altitude. If it takes longer for the signal to reach the receiver, then you’re lower.

[@_Breakdown]

@@xNYCMarc i fully understand what u r saying the concept is/how it works... But does the GPS give u an EXACT altitude? (When u say higher or lower, do u mean generally higher or lower, or does it give an EXACT measurement of an aircraft's altitude?). And is that the same GPS that's used for ADS-B?

[@xNYCMarc]

@@_Breakdown Exact? No. But aviation gps has an accuracy of 6 feet (2-ish meters). If WAAS is active, then it’s accurate to a few centimeters. ADS-B altitude is always barometric or IRS altitude, whichever one your aircraft is using. As far as I’m aware, it never uses the gps altitude. Only the location is gps derived.

The CDI indications drawn on the whiteboard on the approach to the runway are incorrect. It is stated in the example that the aircraft is approaching the runway and it is to the right of centre line. In which case the CDI needle should be out to the left not out to the right as drawn. If the aircraft is out to the right then a move to the left is required to recapture centre line.

At what distances from the threshold does it switch from enroute, to terminal, and then approach?

a GPS receiver SENDS a signal ??? i thought it only received signals !?

[@blueskies8834]

Cone of confusion on a VOR has to do with the shape of the radiated signal. The VOR transmitter is not designed to radiate a signal directly abound the VOR ground antenna. When you fly directly over a VOR ground antenna your receiver is confused because there is no signal there.

in which case would you not have baro info ? in other words, when will you fall in the RAIM only case ?

[@rustypotato1884]

VOR service areas changed at the beginning of 2021.

[@nijatkhudaverdiyev3751]

[@daleramsey8140]

Really good job with your videos. You are presenting nav systems in a way that's very easy to understand. I would add a little constructive help though. GPS receivers are completely passive, they're not sending signals out. The GPS constellation sits about 12,500 NM above the earth's surface...that's about 0.067 sec for a satellite that is directly overhead, and the ones you are receiving are very close to this. I'd take another look at WAAS.... one of the most misunderstood pieces of aviation tools. What is it? Where did it come from? When and why? Answer those and it'll all make a lot more sense. Think Diff GPS, Selective Availability, GNSS and why these things happened in the late 90's. WAAS is taught very poorly because so many instructors don't understand it also. Sorry for the ramble. I really like your videos and want you to keep it up!

[@AeroNerd]

Thanks! And yes this GPS thing has been already addressed many many many many many many times in previous comments and responses and newer videos I made already haha!!! The reason I haven’t deleted this video is that it still has lots of useful info that my pilots have used to help pass their check rides. I am, however, currently in the works of deciding of remaking this video, but if I do, it may not be found due to the way the KZbin algorithm is, which is why I may or may not remake this vid. :) I think as long as everyone is cool with my honest mistake, I may just leave it as is. I don’t know what do you think! Make new video with the GPS correction?
