20130002484 | INDOOR NAVIGATION WITH GNSS RECEIVERS - Global Navigation Satellite Systems (GNSS), such as the US GPS, the European GALILEO and the Russian GLONASS, are based on a mathematical concept known in the art as “three dimensional Trilateration”, where a point is determined by its distances from three other points. The point we wish to determine is the position of a GNSS receiver, typically located by the earth surface, in a car or onboard a ship or aircraft or carried by a person, while the other points are satellites orbiting around the earth. The distances between the satellites and the receiver are estimated by measuring the travelling time of signals transmitted from the satellites, at the speed of light, until arriving at the receiver. Typically, an unobstructed line of sight is required between GNSS satellites and the receiver, for a GNSS receiver to detect these signals and determine its position. Thus, a GNSS receiver located indoors, e.g. inside a concrete building, tunnel or basement, usually cannot determine its position based only on signals transmitted by the satellites. The present invention discloses a method for indoor navigation with GNSS receivers, based on or augmented by signals broadcast by local transmitters, also known as Pseudolites (“pseudo-satellites”). This task is not straightforward since GNSS receivers are designed to monitor satellites orbiting in space around the center of the earth, while pseudolites are typically deployed on the surface of the earth, thus continuously rotate around the earth axis, so unless placed on the equator, these pseudolites do not orbit around the center of the earth, so not easily can emulate GNSS satellites. | 01-03-2013 |
