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.
