1. A method of testing positioning capabilities of a portable device under test, the method including:
communicating with and controlling operation of one or more test instruments, wherein the test instruments include:
a micro-electromechanical sensor signal emulator; anda GNSS satellite constellation RF signal emulator; populating a first panel to be displayed with an identification of the test instruments being controlled; retrieving from storage a test specification file that includes:
a travel path or reference to a travel path followed by the portable device during a test, including for at least the micro-electromechanical sensor signal emulator a pedestrian model or a vehicle ride model that describes orientation and motion of the portable device as it moves along the travel path; andinstructions or references to instructions to be run on the test instruments as the portable device is tested along the travel path; distributing the retrieved instructions or references to the instructions to the test instruments; and during the test, populating third and fourth panels to be displayed, respectively, with reports of signals from the micro-electromechanical sensor signal emulator and the GNSS satellite constellation RF signal emulator.
