A second harmonic frequency is used for the corrections to eccentricity, and the along-track and cross-track positions. A rate term for eccentricity is also included.),
an argument of periapsis of the satellite corresponding to the first cell, a longitude of an ascending node of the satellite corresponding to the first cell([0022] TABLE-US-00001 TABLE 1.1 Current Ephemeris Parameters in the GPS Navigation Message Parameter Description t.sub.oe ephemeris reference time {square root over (a)} square root of the semi-major axis e eccentricity i.sub.0 inclination angle at the reference time .OMEGA..sub.0 longitude of the ascending node at the beginning of the GPS .),
an inclination of the satellite corresponding to the first cell, and a mean anomaly of the satellite corresponding to the first cell at the first epoch time([0154] The nearest cell tower will gather information from the remote server about which satellites should be in view. Satellite information and ranging measurements taken from the cellular network are sent to a remote server. Gauss' solution relates positions at different epochs to their corresponding velocities by incorporating the use of g and f functions. The f and g functions are a common propagation method used in orbital mechanics to relate states at different epochs. The main results, as used in Gauss' solution, of the f and g functions are summarized below. A derivation of Gauss' solution follows the steps used to implement this method. ).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Shin and Li with the terminal device wherein the satellite ephemeris information corresponding to the first cell is in a first format, in a second format, or in both first and second formats; wherein the satellite ephemeris information corresponding to the first cell in the first format comprises: an X-axis parameter of a position of a satellite corresponding to the first cell, a Y-axis parameter of the position of the satellite corresponding to the first cell, a Z-axis parameter of the position of the satellite corresponding to the first cell, an X-axis parameter of a velocity of the satellite corresponding to the first cell, a Y-axis parameter of the velocity of the satellite corresponding to the first cell, and a Z-axis parameter of the velocity of the satellite corresponding to the first cell; and wherein the satellite ephemeris information corresponding to the first cell in the second format comprises: a semi-major axis of the satellite corresponding to the first cell, eccentricity of the satellite corresponding to the first cell, an argument of periapsis of the satellite corresponding to the first cell, a longitude of an ascending node of the satellite corresponding to the first cell, an inclination of the satellite corresponding to the first cell, and a mean anomaly of the satellite corresponding to the first cell at the first epoch time as taught by Garrison. The motivation for doing so would be to reduce the likelihood that the distributed ephemerides are in error due to satellite maneuvers. (Garrison, [0266])
