PORTABLE COMMUNICATION TERMINALS AND METHODS FOR COOPERATIVE POSITIONING SUPPORT DURING POOR SATELLITE COVERAGE

摘要

In one or more embodiments described herein, there is provided an apparatus including a memory having computer code stored thereon, and a processor. The code is configured to cause the apparatus to: receive partial GNSS data from one or more GNSS satellites relating to the geographical location of a first portable electronic device, wherein the received partial GNSS data is insufficient for determining the geographical location of the first portable electronic device; communicate with one or more further portable electronic devices in proximity to the first portable electronic device to access partial GNSS data relating to the geographical location of the respective further portable electronic devices; and use the accessed partial GNSS data of the further portable electronic devices to supplement the received partial GNSS data of the first portable electronic device to thereby determine the geographical location of the first device.
