The invention concerns orientation measuring of a mobile object in space for example a ship's heading using receivers of satellite positioning radio signals. To obtain very rapidly an orientation measurement the method consists in using two receiving antennae located in two points A and B whereof the distance D is well known and in proceeding in the following manner: performing n successive calculations of position of the point A relative to the point B (for example a dozen successive calculations if the distance D is 40 centimetres) from a single set of 2p pseudo-distances measured between each antenna and p satellites. The n calculations correspond to n initial estimated positions (Ae¿1? …

Why it's free to use
- Filed April 12, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 12, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 12, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
