Sony GPS-CS3KA Review (Geo-tagging) and Performance in the Airplane

First few minutes of a flight from Long Beach, CA to Portland, OR

Final moments of the same flight while landing to PDX

A successful logging from Paris to Istanbul

I have been using Sony GPS-CS3KA over a year and so far I have been satisfied with it although I wish some of its features were better. One point I would like to note is that it is possible to log your flight routes (of course as well as photos taken along the flight) with this GPS.  It is pretty exciting to see the actual roots taken while flying between cities. However, in my experience, one should sit by the window for satisfactory performance. If the GPS unit is not close to the window, then it is difficult to get connected to the satellites which unfornutaly means no logging. Also, one should make sure that battery employed within the GPS unit is full before the flights (especially the long ones). While airborne, several times I had difficulties in reconnecting to the satellites after I lost connection due to battery change or any other reason.

Flight from Istanbul to Antalya.

For example, in a particular flight from Istanbul (SBH) to Antalya, it was not possible to grab the signal even during the taxiing. However, approximately 20 minutes after getting airborne, the GPS unit was able to connect to the satellites and the resulting route is given in the accompanying figure on the left.
