“…The use of precision agriculture systems leads to increased efficiency of agriculture, particularly in terms of profitability, productivity, amount of yield, and environmental protection (Keskin et al, 1999;Yakushev et al, 2007;Yakushev, 2016). The costs of fertilizers, seeds, plant protection products, and fuel are reduced by an average of 20% (From precision farming to smart farms, 2019).…”

This study aims to identify the influencing factors and assess the efficiency of implementing automatic driving systems in the key processes of cultivating agricultural crops in the zonal conditions of the region. The research methods included field testing of machine-tractor units equipped with automatic driving systems during the main technological processes of crop cultivation, considering factors such as the specified precision of the automatic driving system, the constructive working width of the machine, the speed of the unit, the operator's qualification, and the soil conditions. It was found that the use of automatic driving systems leads to a reduction in overlap values between adjacent passes of the unit by 3 to 20 times compared to driving without the systems. Moreover, technological and technical indicators showed enhancements ranging from 2.0% to 3.8% during sowing, 4.7% to 6.1% during main tillage, 4.6% to 22.1% during chemical treatment of crops, and 3.4% to 9.9% during crop harvesting. Additionally, it was observed that driving accuracy decreases with increasing speed and low qualification of the operator. The influence of the constructive working width requires further investigation. The impact of soil and climatic conditions on the effectiveness of using automatic driving systems was not established in our current research.

Comparative Appraisal of Three Low-Cost GPS Speed Sensors with Different Data Update Frequencies

Low-cost GPS (Global Positioning System) speed sensors have been available to quantify vehicle speed on different platforms including agricultural tractors in precision agriculture applications such as yield monitoring, variable rate fertilizer and pesticide applications. One of the advances in low-cost GPS receivers is the higher data update frequencies. However, we found no studies on the accuracy of low-cost GPS speed sensors with different update frequencies, especially under variable speed conditions. Thus, this work investigated the effect of the update frequency on the accuracy of low-cost GPS speed sensors under both constant and varying speed conditions. Three GPS speed sensors with update frequencies of 1 Hz, 5 Hz and 7 Hz (GPS1Hz, GPS5Hz and GPS7Hz) were simultaneously tested under the same conditions. A total of 144 tests were conducted on three different days and at three different times of each day with four speed levels and four repetitions. The percent errors were found to be up to 2.3%, 1.8% and 1.4% at constant speeds; up to −47%, −16% and −12% at the increasing speeds and 24%, 6% and 5% at the decreasing speeds, depending on the acceleration and deceleration levels, for GPS1Hz, GPS5Hz and GPS7Hz, respectively. The differences among the error values of the GPS speed sensors were found to be statistically significant (p < 0.05). The GPS speed sensors with higher update frequencies (5 and 7 Hz) provided higher accuracy compared to the one with lower frequency (1 Hz), particularly in the case of higher acceleration conditions. In sum, low-cost GPS speed sensors with higher update frequencies should be used for better accuracy, especially in variable speed conditions.
