An associated task was to address CAN-GPS power needs while maintaining the objectives of portability and rapid deployment. To meet these requirements we developed the PS-S50R50 portable power supply, a 52Ah solar (sealed lead acid, valve regulated) battery housed in a weatherproof transport case. Integrated into the case was a 6A solar charge controller and bulkhead connector to enable input from an external charge source. A 50W solar panel with side-of-pole mounting bracket and array power cable completed the (standard) system.

The PS-S50R50 source has been successfully deployed since the CAN-GPS system's inception. Deployment of the battery case with the CAN-GPS allows field technicians to quickly install and enable CAN-GPS operations for up to five days of unattended operation. This provides engineers ample time to assess the nature of deformation at a site before a solar (or other) recharge source needs to be applied. At the same time, the modularity of CAN-GPS allows integration with any 12VDC power infrastructure, particularly sources tuned for more demanding project applications and environments.
