| Global Positioning System (GPS) is a global navigation satellite system that provides geo-location and time information to a GPS receiver anywhere on or near the Earth. Machine operation track, turning pattern, effective time of field operation, field capacity, field efficiency, machine idle time, etc. can be evaluated precisely by using geo-referenced data recorded by a GPS receiver during field operations. Highly precise GPS receivers are expensive and unaffordable for farmers and farm operators in Bangladesh. Keeping this in mind the scope of an affordable and easy to handle GPS receiver was explored in the study. A GPS receiver was used to record the data generated by combine harvester and mini combine harvester during harvesting. Data were recorded... |
