Skyline Nav AI was born in 2020 from the shared frustration of navigating urban canyons in Greater Boston. Inspired by President John F. Kennedy's vision of tackling the hard challenges, we are driven to revolutionize navigation. Through his US Army service, our CEO, Kanwar Singh, has witnessed firsthand the dangers of relying too heavily on GPS, as his colleagues have often faced GPS denial in combat. Similarly, our Head of R&D, Rajeev Surati, frequently experienced the frustration of unreliable GPS, often finding himself driving in circles around the Boston area. 

Recognizing the need for a more dependable solution, Kanwar and Raj joined forces to transform navigation in GPS-challenged environments. With a dedicated team and support from visionary early adopters, Skyline Nav AI is rapidly scaling, delivering innovative solutions that ensure reliable positioning even when GPS fails.

Imagine waking up one morning and your phone’s little blue dot has vanished, delivery trucks are circling parking lots like lost puppies, planes can’t find airports, and even your morning coffee no longer gets delivered on time. Financial transactions? Delayed. Emergency services? Scrambling with paper maps. That’s what happens when GPS—the unsung hero of our daily lives—goes down. Scary? Yup. Hilarious at times? Definitely. Essential reading? You bet.

In Recalculating: Life When GPS Goes Dark, GPS vulnerability researcher Kanwar Singh takes readers on a whirlwind journey through the hidden world of navigation technologies—and our dangerously fragile dependence on GPS. Spanning stories from lost hikers and jam-happy truckers to real-life airplane mysteries and battlefield electronic warfare, this book lays bare how GPS keeps nearly every sector ticking: transportation, banking, emergency response, power grids, agriculture, and more.

Blending laugh-out-loud anecdotes (from botched first dates to van drivers wandering mountain goat tracks) with eye-opening interviews and expert insights, Singh explains—in plain English—just how thin our safety net really is. Readers will meet everyday heroes, pioneers in navigation tech, and the military brass losing sleep over a single point of failure. The chapters travel from ancient sailors navigating by stars, all the way to modern wars in Ukraine and Middle East, where GPS outages are costing lives.

But this isn’t doom and gloom. Singh arms readers, policymakers, and business leaders with practical solutions: a toolbox of alternatives, from old-school compasses and celestial navigation to quantum, visual, and hybrid systems now being tested around the world (including Singh’s own Pathfinder technology). The message? GPS is amazing, but it shouldn’t be our only plan. There’s hope if we demand resilience, invest in innovation, and remember those basic skills—like asking for directions or reading a map.

Breezy, under 100 pages, and surprisingly fun, Recalculating: Life When GPS Goes Dark is your guide to avoiding chaos if the satellites ever go silent. Whether you’re a commuter, a tech leader, a lawmaker, or just someone who hates getting lost, this book will make you laugh, make you think, and help you prepare. So, don’t take GPS for granted—because when the blue dot disappears, you’ll wish you hadn’t.

Perfect for anyone who wants a clear, entertaining look at the invisible tech holding their world together—and what to do when the GPS stops recalculating. Grab your copy and get ready to find your way!
