Satellites are getting better, and the number of constellations is increasing. Still, many people are not using GNSS terminology — they call it GPS, which is the American GNSS.There is Galileo (European), GLONASS (Russian), or BeiDou (Chinese). Back in 2000, there were 40 GNSS satellites. Fast forward to 2021, and we now have over 100.
Figuring out the viewpoint of the camera is a big part of augmenting reality. The camera has six degrees of freedom.The first three are straightforward — xyz coordinates. Or latitude, longitude, and elevation. Those give you a point in space.For a camera we also need to define the Euler angles — the yaw, the pitch, and the roll — especially if we care about what the camera is pointed at.This is the full six degrees of freedom state, also referred to as the pose.
SBAS stands for Satellite-Based Augmentation System to standard GPS or GNSS signals. It’s a service that improves the quality of positioning from GPS — from multiple meters down to sub-meter level.SBAS uses similar technologies to other high-precision correction services people might be familiar with. It leverages an entire network of continuously operating reference stations around the ground area.
n some respects, we are all drowning in data and one of the big challenges going forward will be filtering the data we have so we can make sense of the world by removing the noise. The Travel Time Platform approaches location-based search form the perspective of the time it takes to reach a destination.
What3words divides the world into a 3 * 3-meter grid, each square is uniquely identified by three words which creates a global reference system that allows people to identify and navigate between these 3*3 meter squares using 3 words instead of longitude and latitude.
Every building has its own geomagnetic fingerprint and by mapping that fingerprint against a floorplan of the building IndoorAtlas is able to provide accurate location and navigation inside. The genius of this system is that it takes advantage of an existing geomagnetic infrastructure.
Location gives context to data but it can also be used to give context to experiences. Radar is a platform for geofencing and location tracking. In this interview with Co founder Nick Patrick we discuss the opportunities around using location to deliver contextualised experiences to users
Smartphones are going to democratize the precise geolocation in the future. In the past years, android has giving developers access to GNNS measurements which is the step before acquiring a position fix and a prerequisite for precise positioning
