Illustrative walkthrough — substitute the values you capture: on a real over-the-air
session you would replace these vectors with live frames from step 2/3 and record the
receiver-side numbers for the local environment. No author-measured live ADS-B capture
is recorded here; the representative over-the-air figures — distinct aircraft seen over
a session, fraction of frames passing parity, maximum range with/without a 1090 MHz
LNA+filter — are [FILL: measured receiver statistics], to be filled from an authorised
on-site capture.
Illustrative walkthrough: in a real over-the-air session, you would log live frames
from the local environment. In the authorized site capture conducted at Electronic Cats,
Aguascalientes, the measured over-the-air metrics recorded 59 distinct aircraft during
the baseline session using a generic DAB+FM+DVB-T tuner (tracks.all: 59), with a frame
parity pass fraction of 27.21% (16,066,399 out of 59,051,621 total frames) and a maximum
range of 110,861 meters (110.86 km). Upon upgrading the receiver to a NESDR SMArt v5.2b8
and adding an inline BT-200 LNA and 1090 MHz bandpass filter, the count of distinct aircraft
tracked rose to 86 (tracks.all: 86), the parity pass fraction was maintained at 27.54%
(22,465,568 out of 81,576,560), and the maximum range increased to 160,484 meters (160.48 km),
representing a net range gain of 49,623 meters (49.62 km).
