NOVELTY - The apparatus has a set of solar tracking devices (32) comprising tracking controllers (16). A network manager has a radio frequency transceiver module comprising a radio communications link with the tracking controllers. The manager organizes and maintains a wireless mesh communication network with the manager and the controllers. A host computer e.g. universal serial bus, operates the tracking controllers. A communication channel connects the computer to a device of the network, and the host computer sends operation data to the controllers traveling across the network.    USE - Apparatus for wireless mesh networking solar tracking devices that are utilized for orienting an object e.g. solar cell, solar concentrator and testing apparatus, with respect to sun.    ADVANTAGE - The apparatus provides a reliable and cost effective remote control, enables monitoring the tracking controllers, and avoids solar tracking controllers from being duplicated at the tracking controllers. The apparatus can be installed in a single place, and allows readings to be propagated over the wireless mesh communications network. The apparatus enables combinations of information to be used for operating the tracking controllers and ensures reliable remote upgrade of operating software in the tracking controllers. The apparatus enables remote monitoring of the performance of tracking devices and tracking payloads, thus eliminating a need for costly and cumbersome wired network infrastructure. The host computer can provide a wide range of tracking controller specific information and system wide information, thus increasing efficiency of the apparatus and reducing mean time repair of the host system. The host computer can provide the operator to perform tracking controller specific and system wide functional control, so as to perform self diagnostics or command the tracking controllers to return to a stow position in case of high winds.
