1. A method comprising:
determining known positions of a first subset of Electronic Shelf Label (ESL) devices;
receiving positioning measurements for each ESL device in a second subset of ESL devices;
estimating a first position of each ESL device in the second subset based on the positioning measurements received for that ESL device and the known positions of the first subset;
determining a positioning error associated with the first position of each ESL device in the second subset;
identifying at least one ESL device in the first subset for which a known location is within a vicinity of the first position of each ESL device in the second subset; and
estimating a second position of each ESL device in the second subset based on the positioning error and additional positioning measurements received for that ESL device from the at least one ESL device in the first subset identified for that ESL device in the second subset.
