1. A node of a satellite constellation system, the node comprising:
a global positioning receiver configured to receive first signaling from a first plurality of non-LEO (low Earth orbit) navigation satellites of a constellation of non-LEO navigation satellites in non-LEO, wherein the first plurality of non-LEO navigation satellites include four or more non-LEO navigation satellites of the constellation of non-LEO navigation satellites that are in reception range of the global positioning receiver;
a transceiver configured to send and receive inter-node communications with other nodes of the satellite constellation system;
a backhaul transceiver configured to receive precise point positioning (PPP) correction data associated with the constellation of non-LEO navigation satellites, wherein the PPP correction data includes orbital correction data and timing correction data associated with the constellation of non-LEO navigation satellites, and wherein the PPP correction data is received separately from the first signaling;
at least one processor configured to execute operational instructions that cause the at least one processor to perform operations that include:
determining, based on the PPP correction data, a state of the node of the satellite constellation system; and
generating a navigation message based on the state of the node of the satellite constellation system, wherein the navigation message includes a timing signal and a position of the node of the satellite constellation system and the navigation message further includes the orbital correction data and the timing correction data associated with the constellation of non-LEO navigation satellites; and
a navigation signal transmitter configured to broadcast the navigation message to at least one client device, wherein the at least one client device is space-based, the navigation message facilitating the at least one client device to determine an enhanced position of the at least one client device based on the navigation message.
