Recalculating: Life When GPS Goes Dark:

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.
