Tactical NAV

iOS Universel / Navigation

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.

**A Personal Message from Jonathan**

What’s up, guys — I hope you're all doing well. This is Jon, creator of Tactical NAV (TACNAV‑X).

As many of you know, I built this app downrange as a Captain in the Pech and Korengal Valleys of Afghanistan, and I’ve carried that mission with me ever since.

TACNAV‑X was born out of my commitment to honor the brothers we lost in 2010 and 2011. For me, this will always be more than software — it’s a living tribute to their memory. They deserve nothing less.

I also want to be real with you. Over the past few months, I’ve been undergoing treatment for my TBI. It hasn’t been easy, but continuing to serve through this app is what keeps me going. I know that might sound a little cheesy, but I mean it.

That’s why I’ve made drawing mode free in this latest update. It was previously an in‑app purchase, but I don’t want there to be any barrier when you need it most, or make you feel like I’m taking advantage of you.

Offline mapping mode is still available as a one-time purchase or subscription. And I assure you, this isn’t about making money. It’s simply what’s required to pay my developers, support updates, and keep the app alive.

Bottom line, your feedback shapes everything I do, and there’s a lot more to come.

If you have ideas, requests, or just want to connect, please email me anytime at jon@tacnavx.com.

Thanks again for your continued support — and for believing in the app.

Take care, guys!

– Jon
