Abstract
The present disclosure is directed to a location tracking system and device that uses spline coefficients, a timing parameter, and a number n of spatial positions to be interpolated in a location message payload rather than the actual satellite coordinates.
Claims20
A method, comprising:
- receiving, by an antenna of a location tracking device, a plurality of radionavigation signals from a plurality of satellites, each radionavigation signal comprising orbital data associated with a spatial position of a respective satellite and a time of radionavigation signal transmission by the respective satellite;
- determining, by a microprocessor of the location tracking device, a plurality of spatial positions associated over time with the location tracking device based on the plurality of radionavigation signals;
- transforming, by the microprocessor, the plurality of spatial positions into a plurality of spline coefficients defining a spline curve;
- and
- transmitting, by the microprocessor, the spline coefficients, a timing parameter, and a number of the plurality of spatial positions to a location tracking server.

A location tracking server, comprises:
- an antenna;
- a network interface in signal communication with the antenna;
- a microprocessor n communication with the network interface:
- and
- a computer-readable storage medium, coupled with the microprocessor, comprising instructions that, when executed by the microprocessor, cause the microprocessor to:
