20 Claims

1. A ground-based node of a satellite system, the ground-based node comprising:

an interface configured to communicate with at least one ground station;

at least one memory that stores operational instructions; and

at least one processor configured to execute the operational instructions, wherein the operational instructions, when executed, cause the at least one processor to perform operations that include:

(a) communicating control data, via the at least one ground station, with a constellation of LEO navigation satellites in LEO around the earth, wherein the control data includes telemetry, tracking and command (TT&C) information corresponding to the constellation of LEO navigation satellites;

(b) transmitting, via the at least one ground station, corrections data to a plurality of LEO navigation satellites of the constellation of LEO navigation satellites;

(c) receiving, via at least one global positioning receiver, a first collection of observations based on signaling from non-LEO navigation satellites of a constellation of non-LEO navigation satellites in non-LEO around the earth, the signaling including collected observations from the constellation of non-LEO navigation satellites;

(d) receiving, via the at least one ground station, a second collection of observations based on navigation messages from the constellation of LEO navigation satellites, wherein the navigation messages facilitate client devices to determine their enhanced position when received in conjunction with second signaling from the constellation of non-LEO navigation satellites, and wherein the navigation messages are generated by the constellation of LEO navigation satellites in response to the corrections data;

(e) updating the corrections data based on the first collection of observations, the second collection of observations and based on telemetry data corresponding to the constellation of LEO navigation satellites included in the TT&C information; and

(f) repeating steps (a)-(e).
