EngineerTact: Geo & RF

EngineerTact is an offline field toolkit for engineers, land surveyors, RF technicians, and field operators across all domains — land, sea, and air.

KEY FEATURES:

• WGS84 Geodetic Coordinate Conversion — Convert between Geodetic (Lat/Lon/Alt) and ECEF (X/Y/Z) using the Bowring iterative algorithm. Real-time ENU Local Tangent Plane target tracking with bearing and range.

• RF & Radar Calculator — Compute Free Space Path Loss (FSPL), Radar Line of Sight (4/3-Earth model), first Fresnel Zone radius, and signal wavelength. All calculations run on-device.

• Mission Brief Planner — Build complete field mission briefs with route distance (Haversine), bearing in degrees and NATO mils, estimated time of arrival, and RF link margin. Save and reload briefs on-device.

• Aerospace & Maritime Converter — Convert speed (knots, km/h, m/s, Mach), altitude (ft, m, FL), pressure (hPa, inHg, psi), and ISA atmospheric parameters with full unit coverage.

• Number Base & Data Converter — Convert between decimal, hexadecimal, binary, and octal. IEEE 754 float analysis. Bit-width calculator.

• Formulas & Reference — Full mathematical reference for FSPL, WGS84 geodesy, Haversine, radar horizon, Fresnel zone, and NATO unit standards.

All calculations are performed entirely on-device. No network connection, no account, no tracking, no ads.
