ESA plans to use its upcoming Lunar Pathfinder mission to experiment with expanding sat nav coverage to the Moon. By tuning in to the Galileo and GPS satellite constellations, the goal is to provide more precise fixes for spacecraft in lunar orbit.

If the smart specs already on the market aren't enough to get you excited, why not make your own? That's exactly what electrical engineer and product designer Sam March has done, with the help of a CNC router and some app coding.
-
MIT scientists have developed an acoustic system that acts like an underwater GPS, yet doesn't need batteries to operate. The system is instead powered by modulated audio signals reflected from the environment to provide net-zero energy positioning info.

NASA's New Horizons deep-space probe has, for the first time, returned images to Earth that showed stellar parallax, or how the positions of stars shift when seen from two different places. This could one day be used for interstellar navigation.
-
The Global Position System (GPS) has turned 25 years old. Operated by the US Space Force, the constellation of navigational satellites went fully operational on April 27, 1995, though US Space Command made the formal announcement in July of that year.

When a driverless car or autonomous drone loses GPS contact, it utilizes a tool known as an inertial measurement unit (IMU) to keep track of its orientation. Such devices could soon be more accurate than ever, thanks to a tiny new gyroscope.
-
Many drones already utilize ultrasound to detect obstacles lying directly in their path. A new drone system, however, uses sound to determine where all of the walls are within a room – providing guidance when vision- or light-based systems cannot.
-
An engineering team at MIT has been working on new navigation software that can enable delivery robots to recognize the typical features of a front yard, and in doing so, find their way to the front door in a far more efficient manner.
-
Hazardous places such as burning buildings can be dangerous to explore, which is why scientists are increasingly looking at using swarms of tiny drones to do the job. A bioinspired navigation system could help make such life-saving swarms a reality.
-
In recent tests, it has been shown that a depth perception-boosting headset could help legally-blind users to avoid collisions.
-
The SmartHalo was a particularly cycling navigation tool that caught our eye back in 2015, and now its creators are back with a new and improved version that promises greater connectivity and puts fitness data right in the rider's line of vision.

Ordinarily, when we hear about robots or other devices that are able to independently navigate outdoors, it's a given that they use GPS. French scientists have developed an alternative, however, in the form of a six-legged robot that navigates like an ant.
