In GPS module, i are getting information about

- latitude and longitude
- Time
- Horizontal Estimated Positional Error
- Heading
- vertical speed
- horizonatl speed
- Altitude
- Location uncertainty angle
- Standard deviation of axis along
- Standard deviation of axis perpendicular to

How can we calculate the velocity of GPS device based above information?

Can any one explain it? if possible with example.

Best Regards
