Figure 1 Autopilots Work with GNSS (GPS/GLONASS/BDS) and Differential Reference Station
During the operation, GNSS reference station broadcasts the satellite reference
observation data via the data transceiver, and the autopilot precisely calculates the
position and speed of itself with GNSS satellite signal and reference station signal
received. Following the specified operation route, autopilot drives the
electro-magnetic hydraulic valve to realize the guidance of wheel movement and
operation route auto-tracking of the agricultural vehicles. For a single GNSS reference
station, it can serve as many autopilots as required at the same time. However, the
work area it may serve depends on the radio transmitting power of the reference
station. In case of portable reference station, the work area usually is within 3km,
while in case of stationary reference station, the work area can be up to around 20km
(The work area will be reduced accordingly when there is windbreak and unfavorable
topography between the reference station and agriculture machines in work).
This user manual introduces the components, installation, commissioning and
operation of AG960 as well as the daily maintenance and troubleshooting for common
issues of the system.
