GPS Loggers
For my case study I did something for the company Thales, which are working at radar systems. They asked me to search for GPS loggers (that are handsome and not to expensive) on the Internet which are still working when an airplane goes at high speed around a corner. If I would found some probably good ones. Thales would order these GPS loggers so I could check whether they really work.
During the first part of my case I was searching literature on the Internet about GPS loggers. Soon I found one GPS logger on the Internet that is logging data with 10 points per second instead of 1 point per second. I set this GPS logger high on my list of probably good working GPS loggers, because if an airplane is turning at high speed then this one is logging a lot more points, so this one is probably more precise. After a lot of researching I found two GPS loggers which are made for model airplanes, so they are good in flying objects. One of these two is also logging 10 points every second, so it looked hopeful. Further I found a few more GPS loggers which are probably okay, but don’t have really exceptional properties. I made a list of all the GPS loggers that I found in Excel with all their properties and advantages and disadvantages, which I sent to Thales.
Thales let me know that they would order the three GPS loggers which were on place one till three on my list. Two weeks later I could continue with my case, namely testing the three GPS loggers plus one they already bought. This part of my case was really fun, I took the GPS loggers everywhere. I went on the train with them, in the car, and even in a lot of roller coasters! I compared the different GPS loggers, and I saw that almost all of them were working well in the train and car. But unfortunately no one was working well in the roller coaster. I gave all the results to Thales. They are satisfied with my testing and are now going to test the GPS loggers on different flights of airplanes.
