• ## Velocity Plots from the boat experiments

Posted on July 19th, 2010

This is the Velocity VS. Time plot from June 30, 2010 at 2pm in which the velocity of the Savitsky does not match with the radial velocity along the entire time. This is because the boat was not drive towards and away to the antenna all the time. As an example the time of 2:25pm was look in the GPS data to find the corresponding coordinates in the boat path.

Here is shown were was the boat at this time. It clearly seen that it has a component of the velocity vector and because of that, the boat speed is different.

This is the plot of Velocity VS. Time from Savitsky’s GPS boat path on July 13, 2010. The velocity match very well with the radio velocity computed by the MATLAB code using the doppler shift. This is because the boat was moving towards and away from the antenna and the velocity of the boat should be the same of the radial velocity.

This is the boat path related to this data.

• ## June 30 – AIS data plots

Posted on July 7th, 2010

Plots from the AIS data gathered during the morning and afternoon experiments on June 30, 2010. The time in the data is not changing, still have to figure out why.

• ## AIS data from June 30 Morning Exercise

Posted on July 1st, 2010

Here is a plot of the AIS data from the morning of the exercise.  This gives you an estimate of the range of AIS data we are capable of receiving with the AIS receiver on the 6th floor of the Babbio building.
