MGRS / USNG Vector Description

MGRS / USNG Vector Professional Land Navigation Tools – Offline & Privacy-Focused

MGRS Vector is a precision land navigation toolkit built for military personnel, SAR teams, hikers, outdoorsmen, and serious navigators who require accurate, offline-capable tools in the field.

No ads. No data collection. No network required.

Three powerful navigation tools in one app suite.

━━━━━━━━━━━━━━━━━━ 1) MGRS Vector ━━━━━━━━━━━━━━━━━━

Calculate accurate MGRS / USNG polar vectors (distance + azimuth) from two coordinates — instantly and offline.

Whether you’re plotting a mission, navigating cross-country, or training in land navigation, MGRS Vector replaces manual protractor math with precise calculations.

Key Features:

• Works completely offline — no internet required

• On-demand GPS use (no constant battery drain)

• Detects and displays GPS accuracy

• Rejects inaccurate fixes (≥ ±20m)

• Supports 2-, 4-, 6-, 8-, and 10-digit coordinate precision

• Calculates: - Distance (meters) - Magnetic azimuth - Grid azimuth - True azimuth - Back azimuths

• Retrieves current local magnetic declination

• Converts distance to pace count

• Clipboard copy & share support

• Works as a pure mathematical (Cartesian) vector calculator

• Uses WGS84, the standard reference system and datum for the U.S. Department of Defense.

• Designed for field reliability and low power consumption.

• Verified with National Geodetic Survey calculator.

━━━━━━━━━━━━━━━━━━ 2) Pace Count Conversion ━━━━━━━━━━━━━━━━━━

Purpose-built pace count calculator for field navigation.

Stop doing mental math under stress.

Features:

• Up to four named pace count profiles (e.g., LBE, Night, 72-hour pack)

• Convert meters → paces

• Convert paces → meters

• Automatically inject profiles into MGRS Vector • Instant PM factor calculation

━━━━━━━━━━━━━━━━━━ 3) Cartesian Coordinate Converter ━━━━━━━━━━━━━━━━━━

Convert latitude/longitude coordinates into MGRS or USNG format.

Perfect when receiving coordinates from:

• GPS devices

• Map applications

• Web sources

• SAR or field reports

Features:

• Supports +/– or N/S E/W notation

• Supports Decimal Degrees (D), Degrees Minutes Seconds (DMS), and Degrees Minutes (DM)

• Auto-detects clipboard coordinate formats

• One-tap injection into MGRS Vector

━━━━━━━━━━━━━━━━━━ Privacy & Performance ━━━━━━━━━━━━━━━━━━

• No ads — ever

• No tracking

• No "phoning home"

• No unnecessary permissions

• No network required for core functionality

• Extremely lightweight and battery-conscious

• Uses device GPS only when requested

• Android versions supported 8.1/9.0 to 16 and beyond

• Suuported devices from small to large phones, foldables, tablets

━━━━━━━━━━━━━━━━━━ Documentation ━━━━━━━━━━━━━━━━━━

• Complete 40+ page manual

• Built-in

• Display with internal viewer which has hyperlinked text sections, table of contents, figures

• Optionally display with external viewer

Built for serious navigators who demand precision, versatility, and reliability in the field.
