Abstract: A printed circuit card assembly (PCBA) configured for retrofitting a conventional electromagnetic locator device (ELD) for a simulator system includes a printed circuit board (PCB) having data connectors connected via a switch to the ELD, a low-power radio frequency (RF) receiver for receiving emulated electromagnetic (EM) field data, a processor for reading the emulated EM field data that includes constituent parts, wherein each constituent part corresponds to EM field data for a specific one of the digital signal processor on the conventional ELD, disassembling the emulated EM field data into its constituent parts, and transmitting to the digital signal processors, via the data connectors, the constituent part of the emulated EM field data that corresponds to said digital signal processor, thereby emulating an EM field on the conventional ELD.

Abstract: An apparatus for retaining a mobile computing device during data collection and field mapping procedures is disclosed. The apparatus comprises a base element configured to be gripped by a user, a shaft comprising a sliding traction mechanism and a first end, wherein the sliding traction mechanism extends from the first end, a clamping mechanism configured to be affixed to the shaft comprising a second end, wherein the first end and second end cooperate to define an interior space sized for retention of the mobile computing device, and a domed housing configured to house an antenna and a global navigation satellite system (GNSS) processor configured to be communicatively coupled to the mobile computing device.
