Abstract: The instrumentation package is transportable to remote sites solely by a light helicopter. Accordingly, three skids are provided, each of which weighs less than 1,200 pounds. An instrument skid comprises a generally, horizontally disposed frame having jacks mounted on it for leveling. Instruments and control elements are also mounted to the frame, preconnected at the factory, and protected from weather. A separate battery skid is provided which is mounted on the instrument skid at the site. A solar array skid, the sloping roof of which comprises solar cells is separately transportable by helicopter to the site and is lowered onto and fastened to the instrument skid. The instrument skid preferably has a self-contained generator mounted thereon when it is transported to the site. An instrument and antenna mounting tower for telemetry, if desired, is broken down and carried within the solar array skid to the site and then mounted on the rear of the instrument skid and tied to the solar array skid.
