The portable precision location mapper provides the agricultural user with a mechanism for determining and recording positions with high precision. This device uses the Global Position System satellite signals, differentially corrected for local and induced distortion, together with an optical rangefinder for its position determination. Software and control panel hardware specifically developed for the agricultural applications provide useful interface with the user. The unit is developed for ground based applications. The portable precision location mapper was found to be both technically and economically feasible in Phase I. A complete brassboard unit will be assembled. Carrier phase measurement will be applied to improve the accuracy. Field testing will be performed in both a controlled test range and in an agricultural environment. An assessment of the manufacturing costs will be performed.
Anticipated Results:High resolution mapping of fields can be used to identify variability of weeds, soil moisture, drainage, organic matter, and pest infestation.
