11. IRNSS - India's regional navigation system.

12.The GPS signal contains a 'pseudo-random code', ephemeris (pronounced: ee-fem-er-iss) and almanac data.

13.With a minimum of three satellites, your GPS receiver can determine a 2D position fix.

14.With four or more satellites, a GPS receiver can determine a 3D position fix.

15.GPS receivers are line-of -sight instruments, they need to see the sky to operate.

16.GPS time is accurate to about 14 nanoseconds.

17.GPS can determine Velocity (speed you are travelling).

18.GPS can determine Time.

19.GPS can determine Location (where you are).

20.GPS can determine Speed.

21.GPS can determine Bearing.

22. GPS can determine Sunrise and sunset.

23. GPS can determine Distance to destination.

24. GPS can determine Trip distance.

25. GPS-based location devices help police recover stolen cars.

26.Homer Simpson has the most downloaded GPS voice in the world according to the World Guinness Book of World Records.

33. GPS was fully operational running with 24 satellites in year 1994

34. 1983 - GPS system was made available to the civilians.

35. Civilian GPS uses the 'L1' frequency of 1575.42 MHz.

36.Civilian GPS applications use with three basic components: absolute location, relative movement, and time transfer.

37. Transmitter power is only 50 watts or less.

38. A GPS satellite weighs approximately 2,000 pounds.

39. Each satellite is built to last about 10 years.

40. Each satellite is about 17 feet across with the solar panels extended.

Anyway, GPS now is must have app whatever if your are driving, hiking, sports, business etc.
