Portable communication terminals and methods for cooperative positioning support during poor satellite coverage
First Claim
1. An apparatus comprising:
- at least one non-transitory memory; and
at least one processor, wherein the at least one non-transitory memory comprises computer code stored thereon, the computer code being configured to, when run on the at least one processor, cause the apparatus to perform at least;
receiving partial GNSS data from one or more respective GNSS satellites relating to geographical location of a first portable electronic device, wherein the received partial GNSS data is insufficient, by being corrupt, for determining the geographical location of the first portable electronic device;
communicating with one or more further portable electronic devices in proximity to the first portable electronic device to access corresponding partial GNSS data relating to geographical location of the respective further portable electronic devices, the partial GNSS data of the one or more respective further portable electronic devices being corrupt;
measuring a synchronisation error between the first and respective further portable electronic devices based on a comparison between the respective further and first portable electronic device partial GNSS data to allow for synchronisation of the respective further and first portable electronic device partial GNSS data, wherein the synchronisation error is measured by identifying a time difference between one or more common timestamp peaks of the partial GNSS data from the respective further and first portable electronic devices; and
using the measured synchronisation error and 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 portable electronic device.

Abstract
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.

13. An apparatus comprising:
-
means for receiving partial GNSS data from one or more respective GNSS satellites relating to geographical location of a first portable electronic device, wherein the received partial GNSS data is insufficient, be being corrupt, for determining the geographical location of the first portable electronic device; means for communicating with one or more further portable electronic devices in proximity to the first portable electronic device to access corresponding partial GNSS data relating to geographical location of the respective further portable electronic device, the partial GNSS data of the one or more respective further portable electronic devices being corrupt; means for measuring a synchronisation error between the first and respective further portable electronic devices based on a comparison between the respective further and first portable electronic device partial GNSS data to allow for synchronisation of the respective further and first portable electronic device partial GNSS data, wherein the synchronisation error is measured by identifying a time difference between one or more common timestamp peaks of the partial GNSS data from the respective further and first portable electronic devices; and means for using the measured synchronisation error and 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 portable electronic device.

14. A method comprising:
-
receiving partial GNSS data from one or more respective GNSS satellites relating to geographical location of a first portable electronic device, wherein the received partial GNSS data is insufficient, by being corrupt, for determining the geographical location of the first portable electronic device; communicating with one or more further portable electronic devices in proximity to the first portable electronic device to access corresponding partial GNSS data relating to geographical location of the respective further portable electronic devices, the partial GNSS data of the one or more respective further portable electronic devices being corrupt; measuring a synchronisation error between the first and respective further portable electronic devices based on a comparison between the respective further and first portable electronic device partial GNSS data to allow for synchronisation of the respective further and first portable electronic device partial GNSS data, wherein the synchronisation error is measured by identifying a time difference between one or more common timestamp peaks of the partial GNSS data from the respective further and first portable electronic devices; and using the measured synchronisation error and 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 portable electronic device. - View Dependent Claims (15)
