Abstract: The present invention provides a global, cislunar, interplanetary, local navigation system that can provide position, navigation, and/or time (PNT) to users. Embodiments may use scanning active electronically steerable antennas (AESA) on multiple satellite (or other) sources that scan their beams over a volume of interest. This enables the use of high-gain antenna beams while at the same time spanning an operating volume with multiple users. Users and satellite sources can establish bilateral links and perform two-way time transfer (TWTT) to provide users with range and time correction. Bilateral links can provide authentication, registration of users, user-specific security keying, a means for allowance and/or denial of access, and enables a paid service. The scanning beam approach means each user can get a ranging/time update for only a fraction of the time.

Abstract: A multi modal communication system for sending and receiving transmissions may be disclosed. The multi modal communication system may include a server device that is configured to selectively send and receive communication across multiple communication paths. The communications paths may include at least a first communication path and an alternative communication path. The multimodal communication system may include numerous nodes, at least one node being a gateway node, a relay node, or a client node. The plurality of nodes may communicate with the server device, communicate between respective nodes using a message routing and forwarding protocol, and maintain a network map. Additionally, some nodes may be configured to communicate wirelessly with the at least one client node. Furthermore, the gateway node may be configured to directly communicate with the at least one server device via the alternative communication path.
