Not a big enough application to warrant a full review, but I still wanted to highlight GPS Toolbox as a cheap utility that satisfies a very specific need: looking under the hood at what your Symbian^3 smartphone's GPS is doing. How good or bad is your satellite lock and where exactly are you in terms of latitude and longitude?

S60 3rd Edition and S60 5th Edition users had it easy - a built-in GPS Status/Location function provided a map of the sky, showing GPS satellite positions and their lock status, along with detailed position. With Symbian^3, Ovi Maps now manages so much of Symbian's positioning that it's assumed you don't want to be bothered with the technical details.

Yet I do. Which is what drew me to GPS Toolbox, a quid in the Ovi Store:

The basic sky view and the main menu. Satellites in yellow are visible, those in orange are actually locked onto.

Position accuracy shows the possible error in your GPS fix over time. A novel view! Position fix gives your raw lat/long and altitude.

Really getting under the hood now, you can view which NMEA data strings are being output by the GPS receiver chip and then take a peek into the raw data stream.
