Author Affiliations +
The operational lifetime of an Unattended Ground Sensor (UGS) depends on the power consumption of the package and the space allocated for batteries. Solar cells have the potential of dramatically increasing operational lifetimes of UGS instruments by providing supplemental power, but in this application solar cells are subject to a number of non-traditional constraints. There are UGS applications where the solar array will need to be covert or have a high shock resistance. It is also possible that a UGS-solar array will be placed in a shaded area or randomly oriented with respect to the path of the sun. This paper will first survey conventional approaches towards solar battery charging and then discuss non-conventional approaches applicable to randomly oriented and covert UGS solar cell arrays.
