Automated portable call collection unit
First Claim
1. An automated portable call collection unit for gathering information used in testing the accuracy of a wireless mobile device locating system, the automated portable call collection unit comprising:
- a GPS ground truth detector configured to detect a location of the automated portable call collection unit based on GPS signals;
a cellular GPS detector configured to detect GPS signals identified by a signal-identification communication from the wireless mobile device locating system;
an internal clock configured to keep time and to synchronize its time to GPS time as announced periodically by GPS time signals;
a cellular network communication system configured to;
wirelessly request and receive the signal-identification communication from the wireless mobile device locating system over a cellular communication network;
wirelessly send information to the wireless mobile device locating system over the cellular communication network about;
one or more locations detected by the GPS ground truth detector;
the GPS signals that are detected by the cellular GPS detector; and
one or more of the times on the internal clock; and
a controller configured to repeatedly cause the cellular network communication system to wirelessly request and receive the signal-identification communication and to send the information about the GPS signals, the locations, and the times, all in a manner that insures that the accuracy of the wireless mobile device locating system is not tested before the internal clock is first synchronized to GPS time following application of operating power to the automated portable call collection unit.

Abstract
An automated portable call collection unit (APCCU) may gather information used in testing the accuracy of a wireless mobile device locating system. A GPS ground truth detector may detect the location of the APCCU based on GPS signals. A cellular GPS detector may detect GPS signals identified by a signal-identification communication from the locating system. An internal clock may keep time and synchronize its time to GPS time as announced periodically by GPS time signals. A controller may repeatedly cause a cellular network communication system to wirelessly request and receive the signal-identification communication and to send the information about the detected GPS signals, the locations, and the times. All of this may be done in a manner that insures that the accuracy of the locating system is not tested before the internal clock is first synchronized to GPS time following application of operating power to the APCCU.
