Open the CIPO recordAbstract From the Canadian patent
Exemplary embodiments of the present invention describe terminal position location methods and systems. Relative powers of nearby spot beams which are generated by array antennas are determined. For example powers from six , neighboring spot beams relative to a center spot beam within which a mobile station is currently operating, can be measured relative to the power of the center spot beam. Using information from these measurements the mobile , stations position can be determined using for example, an exponential model , of the spot beam pattern.

Why it's free to use
- Filed January 31, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 31, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 31, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
