This week, I worked on the final presentation and collected more data to help Udit and Rhea refine the multilateration algorithm:
At Tamal’s recommendation, I let the anchors ‘warm up’ by running them continuously for at least 30 minutes prior to testing. This contributed to a significant reduction in timestamp reception variance in real-world testing, sampled below:
Test 10 — Stats of Direct Difference in Synchronized Reception Timestamps between Anchors that are equidistant from Tag, in Nanoseconds:
Mean = -0.11842105263157894,
Median = 0.0
St. Dev = 0.8105733069084967

Test 11 – Stats of Direct Difference in Reception Timestamps between Anchors that are equidistant from Tag, in Nanoseconds:
Mean = 0.3470031545741325,
Median = 0.0,
St. Dev = 1.4427340556024508
We are on schedule for our presentation this week and demo + report next week. Next week, I will work on the report and, if needed, scale up the experiment for more anchors.
