A refuse vehicle includes a chassis supporting a plurality of wheels and a vehicle body. The vehicle body defines a receptacle for storing refuse. A lifting system is movable between a first position and a second position vertically offset from the first position. A processing unit is in communication with a sensor. An imaging device is in communication with the processing unit and is positioned on the refuse vehicle to have a field of view extending outwardly away from the refuse vehicle. The processing unit controls the imaging device to capture an image upon receiving an indication, from the sensor, that an indicator is present within the field of view. In some embodiments, the indicator is the presence of a positive object, like a waste container. In other embodiments, the indicator is the omission of an object (e.g., no container is detected) within the field of view.

A method for processing GPS position signals in a vehicle is proposed, wherein the GPS position signals of the vehicle are received successively at a predefined time interval and are processed in order to control the vehicle, and wherein at least one intermediate position value of the vehicle is determined within the time period formed by the time interval between two successive GPS position signals. Furthermore, a control device is proposed for carrying out the method.

Traditional “low-to-high waveform change” timing markers, in navigation or GPS signals, can be easily naturally or maliciously altered and require unshareable, high-resolution, high-capacity channels, often not government available. Whereas, message text format methods include proven error correction, redundancy, encryption, jam-resistance, concealability, spoof-resistance, multiuser, delayable messaging, channel efficiency, and downstream authentication. Herein, “virtual timing markers” exploit message format strengths and more. Because many navigating platforms also communicate voice, messages, or data, platforms and multiuser messages can simultaneously and unintrusively share the same transmission signal, which reduces onboard hardware, needed channel capacity, radio frequencies, costs, and infrastructure. FAA mandated, airliner collision avoidance broadcasts of their GPS location can unintrusively commingle navigation messages with aforementioned strengths as precise derivative GPS timing markers on existing, prolific broadcasts having 1000× greater power levels. “Relayed transmission pathways” can eliminate cumbersome traditional nanosecond synchronization of navigation transmitters or exploit inclusion of happenstance neighborhood transmitters. Additional features.
