Tactical NAV vs Land Nav Assistant

BACKGROUND: Built from the ground up in the rugged mountains of eastern Afghanistan, Tactical NAV (also known as TACNAV-X) was developed by a U.S. Army Field Artillery officer with the vision of crafting a low-cost and highly accurate mobile navigation platform tailored for the U.S. military. Tactical NAV’s journey began in the Pech and Korengal Valleys of Kunar Province, Afghanistan. U.S. Army Capt. Jonathan J. Springer, a Field Artilleryman serving as a Fire Support Officer with the 101st Airborne Division (Air Assault), embarked on the development of this tactical navigation platform immediately following the memorial services for Spc. Blair D. Thompson and Spc. Jared C. Plunk, who were killed in action on June 25, 2010. Despite initial rejections by the Department of Defense, Captain Springer remained steadfast in his mission to continue developing Tactical NAV — even to this day. His ultimate goals were (and still are) to make a positive difference for other soldiers and service members and to honor the men and women killed and wounded in battle. He used his life savings to fund and develop TACNAV-X, all with the ultimate hope of saving military lives, and helping his fellow service members in accomplishing their missions at home and abroad. Tactical NAV officially launched on the App Store on February 14, 2011. BUILT FOR ACCURACY: TACNAV-X’s performance accurately matches that of the AN/PSN-13 Defense Advanced GPS Receiver (DAGR). MISSION: Empower military service members with a highly accurate and powerful mobile navigation platform. VISION: Assist and support our nation’s service members with their mobile navigational needs and enable them to operate and win in both training and combat environments. BOTTOM LINE: Tactical NAV has successfully undergone evaluation against Nett Warrior, ATAK, BFT, and other military targeting and navigation systems. Its accuracy is within 1mm of officially approved DoD equipment. IAPs & SUBSCRIPTIONS: Currently, offline mapping mode is available as a monthly or yearly subscription, or as a one-time purchase. Drawing mode, previously an in-app purchase, is now included free for all users. All revenue generated from these features contributes to further development and updates, and a portion of the proceeds are donated to charities that specifically benefit disabled veterans. KEY FEATURES: • A military-quality precision targeting platform • Purpose-built for the individual Soldier • Offline mapping capabilities (complete usage of the app with no emission of a cellular signal) • WGS-84 standard (MGRS, UTM, BNG, and USNG coordinates) • Tactical drawing mode (useful for mission planning, building overlays, targeting, etc.) • Waypoint plotting functionality with military graphics (per FM 1-02.2) • Compass “FastLock” function for capturing quick and precise azimuths • Snap and save photographs onto the main map to increase situational awareness • Location, waypoint, and photo-sharing capabilities (via email and text) • One-button night mode function for low-light situations • Apple Watch support included for free • ‘Go to Grid’ feature for precision planning, drawing of overlays, and dropping waypoints • iOS/iPadOS native code built for austere and contested environments IMPORTANT NOTES: The Department of Defense does not endorse Tactical NAV and TACNAV-X. The app should not replace a government-issued device during life-threatening or combat operations. SUPPORT: If you have any questions about the app, please contact Jonathan Springer directly at jon@tacnavx.com.

Land Nav Assistant accepts MGRS (Military Grid) or Latitude / Longitude coordinates and visually navigates you to each point. This app was designed with Army, Marine, and other military personnel in mind. Use it to correct your Land Nav technique by analyzing your pace count and tendency to veer left and right. Available Input: 8 digit MGRS, 10 digit MGRS, Lat/Lon decimal, Lat/Lon dms, and map input. Angles: degrees or mils Distance: meters/km or feet/miles Speed: kph or mph Use the simple arrow interface or map to direct you to your locations. Your distance, direction, speed, and bearing are shown as you navigate. Long-tap anywhere on the map to get the coordinate for that location. Easily add locations via the Map interface. Plan your course by ordering points, or use the course optimization tool which will help you calculate the shortest path possible! Get distance/direction between two points by tapping the path drawn between them. Satellite, Terrain, Road, and basic Topographic maps show you, your locations, and lets you enter in new ones. Overlay a 1000m or 100m MGRS grid anywhere on the map. Displays distance/direction from your currentl location to all points, or between any two points. Download your Locations as a spreadsheet to save anywhere, or to share with anyone you choose. Import a large set of locations via the web import utility, available at: https://www.gammonapplications.com/land-navigation-services/import This app uses the Military Grid Reference System (MGRS) and Latitude / Longitude. Choose to display your locations as MGRS 10-digit, MGRS 8-digit, or LatLon Decimal. D:M:S can be input in the format DD:MM:SS followed by the appropriate direction (NSWE). Default direction is N, W. DO NOT use this application while learning Land Navigation. Land Navigation is a valuable skill, and should be mastered before using this application. Do not rely solely on this application for navigation, especially when lost. Always be aware of your surroundings.
