Grand Challenges for Engineering aspx Engineer the Tools of Scientific Discovery
Geo-Caching Challange 1.Direct navigation assistance (pre-programmed way-point) 2.Relative Position (distance and angle from first way-point) 3.Absolute Position (latitude and longitude only)
What do all those numbers mean??? ,
What do all those numbers mean??? , Which number indicates how far north or south you are? Which number indicates how far east or west you are? Find out!
What do all those numbers mean??? , How far is it from the northern to the southern end of the field inside the track (in change of latitude)?
What do all those numbers mean???
Discovery: We can use GPS to measure things! = (approximate) length of the football field
What does the GPS receiver tell us? Where we are! = Position Change in Position over time = Velocity Change in Velocity over time = Acceleration Change in Acceleration over time = Jerk
From data to science… Hypothesis: If ________________ then ______________ because _____________________________. If a car accelerates more then it will require more maintenance because acceleration (changing speeds, making fast turns and going over bumps) puts more stress on the car’s components.
GPS Satellite – Receiver Model Question: How many GPS Satellites does a GPS receiver need to “see” to find its position (Latitude, Longitude and Elevation)? Hint: The only information a receiver knows from a satellite is how far away it is. Materials: –You (one person per team will be a receiver, everyone else will be satellites). –Lengths of string (used to represent a fixed distance).
