Everything I can quickly find on the Ground Sensor Surveillance Vehicle indicates that its a classified intelligence gathering platform. Oddly enough the NSN is easy enough to find (2355-01-563-1031) and by looking this up it appears that development for the thing is being managed by the Battlespace Awareness end of the US Navy's Space and Naval Warfare Systems Command. The facility where that end of things operates out of, Space and Naval Warfare Systems Center Atlantic, South Carolina, deals in everything related to "engineering expertise to fabricate, integrate and test for all command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) acquisition engineering and integration."
In short, very specific details will probably be hard to come by.
