A method of verifying accuracy of a perception system of a vehicle includes causing the vehicle to traverse a path around a target that is fixed in an environment. The target has a known pose. The path is configured so that the target comes into a respective field of view (FOV) of each respective perception sensor of one or more perception sensors of the perception system along the path. The method further includes, for each respective perception sensor of the one or more perception sensors, while the target is within the respective FOV of the respective perception sensor, acquiring a respective image of the target using the respective perception sensor; at the perception system, determining a respective pose of the target based on the respective image; and at a computer system communicatively coupled with the perception system, determining whether the respective pose matches the known pose of the target.

Methods for determining corrected positions of a global navigation satellite system (GNSS) rover using a GNSS base station and one or more GNSS reference stations include determining a statistical representation of position measurements from the GNSS reference stations and an instantaneous position measurement from the GNSS reference stations. A position correction is determined based on the statistical representation and the instantaneous position measurement. A corrected position of the GNSS rover is determined based on a position of the GNSS rover and the position correction.

A system for providing manual guidance of a vehicle includes a first inertial measurement unit (IMU) attached to a steering wheel, a second IMU attached to a fixed part of the vehicle, a global navigation satellite systems (GNSS) receiver, a data storage device for storing a pre-planned path, and a feedback module. The feedback module is configured to determine a current angle of the steering wheel, determine a deviation of the current position of the vehicle from the pre-planned path, determine a current heading of the vehicle, determine a current velocity of the vehicle, and determine a desired angle of the steering wheel relative to the vehicle. The system further includes a user interface configured to provide a visual indication of the desired angle of the steering wheel or a deviation of the current angle of the steering wheel from the desired angle of the steering wheel.

A system for vertical accuracy improvement includes a reference station, a rover, and a base station in communication with the reference station and the rover. The base station includes a GNSS antenna, an actuator coupled to the GNSS antenna, a wireless transceiver, a processor, and non-transitory computer readable media comprising instructions executable by the processor. The instructions may be executed to cause the base station to receive a first vertical error from the reference station. The base station may further be configured to determine a second vertical position at which the first vertical error is reduced, and adjust the GNSS antenna to be in the second vertical position. The base station may further be configured to generate correction data based at least in part on the phase of the carrier wave signal at the second vertical position, and transmit the correction data to the rover.

An agricultural implement that includes a slotting mechanism and a slotting actuator is provided. The slotting mechanism is for cutting slots in a drip line in real time in conjunction with ground placement of the drip line. The slotting actuator is for actuating the slotting mechanism. The actuating is controlled by a computer following a slot spacing in a drip line prescription for a field in which a drip line is being placed.

A moisture content sensing system is described comprising a collar mechanically coupled with a clean grain transport system. An extendable support extends through the collar and has an extendable capacitive sensor element disposed at one end. The extendable support is configured to be located at a first position in which the extendable capacitive sensor element is disposed adjacent to clean grain conveyed by the clean grain transport system and moved to a second position wherein the extendable capacitive sensor element is disposed at least partially within the clean grain of the clean grain transport system.
