Nikon has announced a new GPS dongle for its Digital SLR range of cameras on Wednesday.

The new bolt-on accessory will be called the GP1 and add geotaging functionality, similar to the already announced Coolpix P6000 to allow photographers to geotag their images.

Expected to be available in October or November, the new add-on will come in two variants to fit the different DSLR models the company current offers.

The GP1 will support the newly announced D90 as well older models such as the D3, D300, and D700 cameras.
