Per receiver type summary

This section groups the selected stationary logs by gnss_chip. It is the main comparison between L76K and u-blox.

Per log summary

Useful for spotting one bad session that drags down a receiver family.

Combined summary

This pools all selected logs together. Treat it as a site-level rollup, not a "best of breed" answer.

Best-of-breed metric leaders

This section is intentionally narrow: it identifies which receiver family leads each metric across the selected logs. It does not synthesize a fictitious receiver.

metric	better_direction	gnss_chip	metric_value
avg_cn0	higher	L76K	31.37
avg_hdop	lower	MAX-M10S	0.528
avg_sats_used	higher	L76K	5.29
avg_wander_m	lower	MAX-M10S	1.503

Interpretation notes

avg_sats_used: more is generally better.
HDOP: lower is better.
CN0: higher is better.
avg_used_sat_elev: higher generally implies less multipath exposure.
wander: computed as horizontal distance from the mean latitude/longitude of each log's stationary sample cloud. Lower is better, assuming the unit truly remained fixed.
