I hope that helps your brother out. 00:00:00
Thanks for the information on the SHARP program. 00:00:02
My brother is very excited about it. 00:00:04
You're welcome. 00:00:06
May I ask you another question? 00:00:07
It's about global positioning systems. 00:00:08
Of course. What would you like to know? 00:00:10
As a pilot for NASA, how do you use GPS when you're flying? 00:00:12
With GPS's unique ability to provide an exact location at any second, 00:00:15
pilots rely on that for accurate navigation. 00:00:20
That is pretty important when you're flying. 00:00:23
Yes, knowing exactly where you are helps to keep the plane clear 00:00:25
of obstacles and mountains and get you to your destination safely. 00:00:28
How does GPS help you navigate? 00:00:32
GPS devices on aircraft are very similar to the ones you use for geocaching, 00:00:34
just a little more sophisticated. 00:00:39
They show great detail accurately displayed on a graphic map. 00:00:41
We've learned how important accurate maps are. 00:00:44
Yes, and having the capability to always know where you are 00:00:47
combined with an accurate map display 00:00:50
greatly adds to the situational awareness and to the safety of the flight. 00:00:52
What would happen if the GPS device went out while you were flying? 00:00:55
It might make the aircraft unable to fly and land in all types of bad weather. 00:00:58
However, aircraft aren't dependent upon GPS. 00:01:03
All planes and their pilots have the ability to fall back on 00:01:06
traditional modes of navigation that were used prior to GPS. 00:01:09
Just like we had to rely on our good old compass when our GPS went out. 00:01:13
Exactly. At worst, it would be an inconvenience for the pilot. 00:01:17
But he or she would be quite capable of safely flying the aircraft. 00:01:20
That's good to know. Are there any other uses for GPS? 00:01:24
Absolutely. There are all types of navigational uses for GPS. 00:01:27
Oil companies use GPS to help them drill for oil. 00:01:31
Farmers even use GPS to help them plow their fields. 00:01:35
Some have even used GPS to locate a stolen vehicle. 00:01:38
Most activities that benefit from knowing an exact position on Earth use GPS. 00:01:41
Wow, I never realized so many people could use GPS. 00:01:46
Thanks, Mr. Cope. 00:01:49
Maybe we could see GPS in action by taking a quick ride on one of your research planes. 00:01:51
I didn't know you and your brother were interested in flying. 00:01:56
The weather wasn't cooperating for our flight, but it was great to learn more about GPS. 00:01:59
I hope Jacob's meeting with Dr. D goes well. 00:02:04
We still have a lot to learn about GPS and navigation. 00:02:07
