STUDIES OF SMART ANTENNA SYSTEMS IN AGRICULTURAL APPLICATION AND PERFORMANCE OF NOVATEL’S SMART-V1 AND SMART-V1G ANTENNAS

Abstract

This paper discusses the agricultural application and performance of NovAtel’sSMART-V1 and SMART-V1G antennas. In this paper, the results of field tests are presented. This paper also introduces Nov Atel’s newest enhancement to positioning algorithms, GL1DE™. This test was designed to resemble a typical agricultural environment. NovAtel’s SPAN technology was used to collect the GPS and IMU data during the dynamic vehicle testing. Components included a NovAtel Propak-V3 and a Honeywell HG1700 IMU AG58. Data collected during dynamic vehicle testing was post-processed using NovAtel’s Inertial Explorer technology to obtain an antenna trajectory solution. The trajectory solution for each antenna accounted for appropriate lever arm corrections from the INS to the antennas. The expected accuracy of the trajectory was 2-3cm.
