Geotack

The Geotack planetary beacon is a portable demarcation device that allows the user to claim a land plot of 4km x 4km on various types of ground surfaces.

Usage
The Geotack is used to demarcate a land claim of 4km x 4km, which then can be used to submit your claim to the Planetary Development Bureau. The owner then receives a certificate, solidifying that the land is owned by the claimant:

"This certificate entitles the bearer to claim a single piece of UEE declared territory of four (4) kilometers by four (4) kilometers in size for the purposes of residential, commercial, or industrial development. Territory must be filed with the United Empire of Earth Planetary Development Bureau as an uncontested claim along with compatible geographic data of desired parcel in order to be claimed. Once approved, the bearer is entitled to all rights tied to this parcel under the United Empire of Earth’s articles of development (section 36.A.I-IX) and shall be the legal tenant of that property and enjoy all rights therein."

The item was revealed and sold together with the reveal of the Pioneer, a ship that can construct and deploy buildings. The Geotack was obtained when you bought the 4x4km land plot license on the Pledge Store for $50 USD.
