1.1.4 - Operational output.
Results open on a plain-language Summary: a status (CLEAR, WATCH, AT
RISK, CRITICAL or NO DATA) with a one-line reason, then the key
numbers, each next to what it is compared against. Details shows every
value with its comparison and meaning, the weather sources, what
changed, the evidence and its limits. Evidence keeps the full Observed
/ Model-derived / Calculated / Inferred record.
Clearance is stated as metres available versus metres required, with
the margin. Negative clearance is explained as terrain above the line
of sight. The critical point is defined as the point with the lowest
Fresnel-zone clearance fraction, which is not necessarily the point
with the fewest metres of clearance.
Weather provenance: every Open-Meteo value is labelled Model-derived
(a weather-model value at the site coordinates, not a station
measurement). The nearest ECCC station, its distance and observation
time, and why it was selected are shown separately.
Rain handling: rain and showers count as rain. Snow is no longer
treated as rain, and if the source does not split precipitation by
type the value is labelled total precipitation. This changes the rain
rate only for hours with snow or showers.
Adds hourly model weather history per site; each change is stated
against an explicit baseline (for example vs 1 hour ago). The history
is model data, not station observations.
Adds an Ask box: rule-based questions answered only from the current
result, with the supporting evidence cited. Anything it cannot match
is declined rather than guessed.
Adds Export as Excel (.xlsx) with eight sheets: SUMMARY, LINK
ANALYSIS, WEATHER, WEATHER HISTORY, ELEVATION-TERRAIN, EVIDENCE, RAW
DATA, DATA DICTIONARY. RAW DATA holds the un-rounded values with unit,
source and calculation id.
The terrain-clearance and microwave weather-exposure calculations and
the aei libraries are unchanged, apart from the rain and snow handling
above.
Code-quality: Flake8 E741 naming cleanup in the presentation layer
(ambiguous variable name renamed); no functional or engineering
calculation changes. The Excel writer no longer ships an XML reader
(it is a test helper), so the package contains no XML parsing.
1.1.3 - Canada data correction: the bundled Canada Fixed Service
snapshot had one site (Regina, SK, ised-fixed-50.41056,-104.61722)
whose
station role was stored as the literal text "TX" with quote
characters; it is now TX. Nothing else in the snapshot changed: 24,859
sites and 16,956 links,
same ids and order, ISED file of 2026-09-01.
1.1.2 - Qt6 compatibility fixes for the QGIS plugin repository scan:
scoped enum names
(Qgis.RenderUnit.Pixels, QgsSymbolLayer.Property.*,
QgsMapBoxGlStyleConverter.Result.Success) and
QMetaType.Type field-spec annotations in place of QVariant.Type. No
functional changes.
1.1.1 - Static-analysis fixes for the QGIS plugin repository scan:
narrowed two broad
exception handlers in the satellite source (CelesTrak requests now
catch only requests errors;
element-set parsing catches only ValueError/ZeroDivisionError, so
unexpected errors surface in
the satellite status message instead of being skipped), replaced two
lambda assignments with
named functions, and renamed an ambiguous loop variable. No other
functional changes.
1.1.0 - Missing-dependency guard. If aei-link-clearance,
aei-microwave-link-exposure, aei-geo-features
or skyfield is not installed in QGIS's Python, the plugin now loads
and shows a message-bar and log
entry naming what to install, instead of failing with an import
traceback. Adds requirements.txt
listing the required packages (aei-link-clearance is now published on
PyPI).
1.0.0 - First production release. The ISED Fixed Service and SatNOGS
ground-station
snapshots are bundled with the plugin, so Explore no longer depends on
files outside the plugin
directory. Qt6/PyQt6 hardening: the Results Dock and both analysis
parameter dialogs used
PyQt5-only idioms that raised AttributeError on first use under QGIS
4, and a checker
(tools/check_qt6_enums.py) now guards that whole class of defect.
Viewport performance: the live
tower/cellular queries are debounced, skipped entirely while their
layers are hidden,
deduplicated per viewport, and served from a bounded session cache
with negative caching, so
returning to an already-visited extent costs no network. The initial
extent is derived from the
terrestrial home layers instead of the global space layers. Plugin
unload is idempotent and
cleans its own analysis overlays while leaving loaded public data in
place.
0.2.0 - Experimental local development plugin.
