Latitude is measured in these two directions.

What is North or South?

100

Longitude is measured in these two directions.

What is East and West?

100

The acronym GPS

What is Global Positioning System?

100

An object’s change in position relative to a reference point

What is motion?

100

Locations or landmarks that can be stored in your GPS.

What are waypoints?

200

The origin for latitude is...

What is the equator?

200

The origin for longitude is...

What is the Prime Meridian?

200

The GPS Operational Constellation consists of this number of satellites.

What is 24?

200

The formula for distance

What is Distance = Velocity x Time?

200

Sometimes the GPS signal from the satellite doesn’t follow a straight line. This is the bending of light as it travels through one media to another.

What is refraction? 

300

Lines of latitude run in this direction.

What is East/West?

300

The point of origin for longitude runs through this location.

What is Greenwich, England?

300

The GPS satellites orbit schedule of the Earth

What is twice a day?

300

The straight line from the starting point directly to the ending point

What is displacement?

300

The ability to draw a straight line between two objects without any other objects getting in the way.

What is line-of-sight transmission?

400

The degree range for measuring lines of latitude

Both are acceptable...

-What is 0-90?

-What is -90-90?

400

The direction for longitude -25.4570

What is West?

400

GPS satellites use these for accuracy, but because of the expense, most GPS receivers do not.  

What are atomic clocks?

400

A system for specifying the precise location of objects in space and time

What is point of reference?

400

A way of locating a point based on how far away it is from three other points.

What is trilateration?

500

The direction of these latitudes:

-20.7800,   -90.0000,   82.3600

What are South, South, and North?

500

The location of 0.000, 0.000

What is the intersection of the equator and the Prime Meridian?

500

Describe the GPS signals transmission speed.  (Be specific.)

What is signals move at the speed of light which is about 300,000,000 meters per second?

500

The difference between speed and velocity (Be specific and give an example with your answer.)

•Speed describes how fast an object moves measured in m/s (meters per second)

•Velocity describes speed and direction and is measured in m/s + direction (i.e. North, South, East, West, etc.)

500

The GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. This tells the GPS receiver how far away the satellite is.

What is the time difference?
