Global geographic information systems (GIS) company Esri has made What3words available across its ArcGIS platform as a locator, offering a simplified addressing system for computers and mobile devices. What3words marks locations using three easy-to-remember words.

A tiny London-based firm has a way with words, particularly when they are arranged in groups of three. It has parsed the planet into 3-meter-by-3-meter (about 10-foot-by-10-foot) squares in a global addressing system, applying an algorithmic engine to assign three-word identifiers to each and every one of the 57 trillion squares that compose a global map.

The key enabling capability provided for PNT is through the signal transmissions from GPS satellites.

In one way or another, everyone depends on the Global Positioning System, or GPS, to smooth the way they live their daily lives. Already, the United States has more than 30 active GPS satellites that feed data to bolster the ubiquitous ecosystem of connected smartphones and other devices that facilitates comings and goings—whether circumnavigating traffic delays or directing users to the precise location for a steaming cup of coffee.

The final GPS IIR-M satellite was launched in August 2009. A critical GPS governance committee is weighing the possibility of augmenting GPS with an enhanced long-range navigation system, similar to the GPS predecessor first developed during World War II.

When it meets this summer, the National Executive Committee for Space-Based Positioning, Navigation and Timing likely will discuss reviving an enhanced version of a World War II timing system to augment signals from global navigation satellites. Portions of the nation’s critical infrastructure, including defense, transportation and finance sectors, depend on those signals, which are potentially vulnerable to a wide range of threats, including wartime adversaries, terrorists, hackers, natural phenomena and commercially available but illegal jammers.
