Trajectory analysis through fusion of multiple data sources

A method performed by at least one computer processor, said method comprising:

• building an error table comprising:
• identifying a first cell having a first fixed antenna;
• for each of a plurality of mobile devices:
• determining a precise location determined using one of said plurality of mobile devices in communication with said first fixed antenna;
• determining a cellular location determined from a first base station attached to said first fixed antenna communicating with one of said plurality of mobile devices, said cellular location being determined with a first location mechanism;
• determining an error by comparing said precise location to said cellular location;
• and
• aggregating said error for each of said plurality of mobile devices into a first antenna-specific error associated with said first fixed antenna;
• determining a first estimated location for a second mobile device comprising:
• determining that said second mobile device communicated with said first fixed antenna at a first time;
• determining a first cellular location determined from said first base station attached to said first fixed antenna communicated with said second mobile device;
• determining a first error range using said first error associated with said first fixed antenna;
• building an error table by further comprising:
• for each of a second plurality of mobile devices:
• determining a second precise location determined using one of said second plurality of mobile devices in communication with said first fixed antenna;
• determining a second cellular location determined from said first base station attached to said first fixed antenna communicating with one of said plurality of mobile devices, said second cellular location being determined with a second location mechanism, said second location mechanism being different from said first location mechanism;
• determining a second error by comparing said second precise location to said second cellular location;
• and
• aggregating said second error for each of said second plurality of mobile devices into a second antenna-specific error associated with said first fixed antenna and further associated with said second location mechanism;
• determining a second estimated location for said second mobile device comprising:
• determining that said second mobile device communicated with said first fixed antenna at a second time;
• determining a third cellular location determined from said first base station attached to said first fixed antenna communicated with said second mobile device, said third cellular location being determined using said first location mechanism;
• determining a third error range using said first error associated with said first fixed antenna;
• determining a fourth cellular location determined from said first base station attached to said first fixed antenna communicated with said second mobile device, said fourth cellular location being determined using said second location mechanism;
• determining a fourth error range using said second error associated with said first fixed antenna and said second location mechanism;
• and
• determining said second estimated location using said third cellular location and said third error range and said fourth cellular location and said fourth error range.
