GPS units is a fabulous invention that circles the Earth twice a day. This invention can determine your location, and find out other information such as your speed. It can also caculate weather conditions. The best thing about this invention is that it does not require an subscription like other related apps
The history behind it states that the people who created this was Roger L. Easton, Ivan Getting, and Bradford Parkinson. This is an incredible resource. I believe this because if you are lost, you can use this to determine where you are, and where your home is. If you wanted to map a school or anything you could also use this app.
Most importantly, if someone gets lost there relative can use this GPS unit to find it. Another thing that this can do is safe peoples lives. If someone is stuck on the road in the middle of nowhere with no cars, and no phone to contact someone, there family relative can simply use the GPS unit to find out exacaly where one of there cars is.
This invention is really insane. It knows what road your on, and where your headed. It includes the speed limit, and your arrival time. It knows when your North, South, West, or East. It also determines your (latitude, longitude and altitude. It can also track about 8 or more satelites.
In conclusion, the GPS unit is good enough to buy, and can sometimes saves lives. Whether it's a family emergency or just a simple ride to the grocery store, this invention is good enough to use.
If everything but "She" was underlined, then the underlined portion would be the complete predicate, since "She" is the subject of the sentence.
