When you start developing a GPS solution, you have to deal with energy and for this you have to create a strategy based on what you expect and the size of your battery.
Basically, a GPS is consuming about 25mA when running. An active antenna will consume about 10mA more. The first time you start it, it have to sync with the satellites, get the ephemeris then you can position in 2D then in 3D.

The TD1204 is the GPS & Accelerometer version of the sigfox Telecom Design chip. After a previous post about the use of the accelerometers (here) I’m describing how to use the GPS module.
The embedded GPS is based on a UBX G7020 chip. This chip will give you the date, time, longitude, latitude, altitude, speed and direction of the device when activated.

After a long period without any idea commit, I propose to imagine a Digital Camera companion, compatible with the main reflex system canon and nikon. This system would be connected to the camera using the USB channel or eventually a dongle type on usb connector, or eventually a wifi memory card system. This is for the camera side. On a tablet side, all the taken photo would be received and transform. The idea is to add GPS location and easily apply filter like in instagram. This can also be use to make panorama automatically or create HDR.
The choice of an USB direct connection could help to automatically configure the camera like for HDR.
As all the idea in this category, feel free to comment, and develop, if you become rich with it … don’t forget to help me paying my house !
