New York (PRWEB) April 02, 2015 -- ICAP Patent Brokerage announces for sale a patent portfolio disclosing systems and apparatus for decreasing satellite acquisition time by using a reverse-cone technique, available from TeleCommunication Systems, Inc. (TCS) (NASDAQ:TSYS). This portfolio is offered as part of the Internet of Things IP Auction, with a bidding deadline of April 23rd, 2015.

The popularity of location-based services in today’s mobile marketplace demands fast, accurate geolocation. With an early priority date of 2002, and 23 total assets, this is an essential portfolio to wireless telecom and satellite providers.

“The popularity of location-based services in today’s mobile marketplace demands fast, accurate geolocation,” says Dean Becker, CEO of ICAP Patent Brokerage. “With an early priority date of 2002, and 23 total assets, this is an essential portfolio to wireless telecom and satellite providers.”

Key Characteristics & Benefits
The need to select a subset of all available position determination satellites is fundamental to location determination. Every satellite in a non-geosynchronous location-determination satellite constellation orbits the Earth approximately six (6) times each day. At any given moment, it is difficult, but crucial, to be able to determine which of the constellation’s satellites are visible to a mobile device before the device begins to try to determine its location. The process of determining a location “fix” without any foreknowledge of which position determination satellites to which to listen can take 5-6 minutes, longer than most calls, and far longer than most users are willing to wait. Mobile devices need only have a rough approximation of their own location in order to compute which location determinate satellites are best suited to determine a precise location, and that approximate location can shorten the time-to-first-fix to only seconds. By utilizing the location of the cellular base station with which the mobile device is communicating, that approximate location can be quickly provided.

The portfolio from TeleCommunication Systems (TCS) provides for a patented system and apparatus to decrease GPS acquisition time by virtue of elegant mathematics. Because base stations do not often move, it is possible to pre-compute and preserve Earth-center unit vectors representing every cellular base station, making it easier to maintain this pre-computed collection of vectors. Computation of an Earth-center vector to all satellites in a constellation, at any given moment, can also be fast. This approach makes it possible to tell if a satellite is “visible” by selecting a visibility threshold prior to satellite subset determination. Subsequent selection of optimal satellite subsets decreases mobile device time-to-first-fix. The whole of the portfolio includes claims leveraging multiple inverted cones, increasing visibility threshold if the reference base station is further from the equator, and estimating the longest “in-cone” durations for reduced frequency of satellite subset re-selection.

Forward citing companies include Qualcomm, Kyocera, CSR, and Google.
