The baler assembly has a chassis, a front component pivotally coupled to the chassis about a front chassis axis, a gate component pivotally coupled directly to the front component about a component axis, a handler pivotally coupled to the chassis about a handler axis and configured to pivot between a raised orientation and a lowered orientation, and a cradle defined on the handler and configured to selectively receive a pin of the gate component. The baler assembly transitions from a work configuration to a transport configuration by positioning the pin in the cradle and transitioning the handler to the lowered orientation while the gate component pivots about the component axis relative to the front component.
A system and a method are disclosed for determining a heading of a vehicle and a heading of an implement of a farming machine when the farming machine is stationary or moving at a speed below a threshold speed.

A navigation apparatus determines an estimated position of an object. Navigation information that includes a sequence of quantized measurements is received. Each quantized measurement has a corresponding quantization error that is negatively correlated with the quantization error of a prior quantized measurement. The apparatus iteratively performs a navigation update operation that includes determining a state and a covariance matrix of the object for a current iteration based on a state and covariance matrix in a prior iteration. The state includes an end quantization error and a start quantization error. The covariance matrix includes end and start covariance values corresponding to the end and start quantization errors, respectively. Determining the state and the covariance matrix for the current iteration includes replacing the start quantization error with the end quantization error determined in a prior iteration, and updating the state and the covariance matrix via a Kalman filter update operation.

A receiver (12 or 30) or method uses an offset vector to provide seamless switching between a real-time kinematic (RTK) mode and a precise positioning mode (e.g., precise point positioning, PPP) mode. An offset module (130) or data processor (159) is arranged to determine an offset between precise position and the RTK position estimate. Upon loss of the RTK signal, switching to a precise position mode is based on a last available RTK position (e.g., if the precise position mode is converged on a position solution with resolved ambiguities of the carrier phase), wherein the next precise position estimate is compensated by the offset or reference frame bias to avoid a jump or discontinuity in the next precise position estimate.
A system or method uses an offset vector to provide seamless switching between a real-time kinematic (RTK) mode and a precise positioning mode. A correction wireless device (14, 114, 214) is adapted to receive, at the reference receiver (30), a precise signal encoded with precise correction data. A precise positioning estimator (120) of the reference receiver (30) is arranged to determine a precise position based on the measured carrier phase of the received satellite signals and the received precise correction data in a precise correction mode. At the reference receiver (30), an offset module (130) can determine a base offset vector between the precise position and a reference RTK position for the reference receiver (30). At the reference receiver (30), a wireless communications device (14, 114, 214) is capable of transmitting, via an RTK signal, RTK correction data.
An offset module (130) or navigation positioning estimator (57) determines a reference frame bias between precise point positioning (PPP) reference frame and an RTK reference frame, where the PPP reference frame is associated with relative position estimates generated by the relative position estimator (124) and where the RTK reference frame is associated RTK position estimates generated by the RTK position estimator (122). Upon loss of the RTK correction signal, the navigation positioning estimator (57) or controller switches to a relative position mode based a last available RTK position. The relative position estimator (124) determines an estimated relative position based on time-differenced phase measurements by the mobile receiver (12, 30) in the relative position mode. The relative position estimator (124) or offset module (130) offsets the estimated relative position in the relative position mode.
