Aspects of the disclosure relate to a method for determining a location of a first device. The method comprises receiving, by the first device, at least one first signal from at least one second device. The method further comprises determining, by the first device, estimated first signal properties of at least one first signal. Also, the method comprises generating, by the first device, at least one second signal based on at least a portion of the estimated first signal properties. Further, the method comprises transmitting, by the first device, at least one second signal to at least one third device. In one or more embodiments, estimated second signal properties of at least one second signal are determined by at least one third device. In at least one embodiment, the location of the first device is determined by utilizing at least a portion of the estimated second signal properties.

Low cost, size, weight, and power (CSWAP) geolocation capability utilizing signal characteristics passed through to backhaul network

For global navigation satellite system (GNSS)-independent operation of auxiliary PNT systems, one or more ground stations of the auxiliary system have access to a non-GNSS source of precision timing. That source and known locations of the ground stations may be used to derive timing corrections to account for imperfect clocks in the satellites for non-purpose-built satellite systems being used for PNT. Crosslinks between satellites and/or propagation of timing correction through other ground stations are used to better control the timing and resulting precession of PNT in the PNT auxiliary system. The timing correction may be provided as a service to end users, other constellations, and/or other satellite operators.

Satellite-based source of positioning system-independent position navigation and time

For validation of wireless signals, a wireless receiver receives a validation signal that includes information from a target signal. By using digital signature, message authentication code (MAC), and/or hashing, the validation signal is verified to be from a trusted source. By comparing the information from the verified validation signal with the target signal, the target signal is confirmed to be genuine or not a spoofing signal. In one approach, the validation signal is provided from a different transmission source than the target signal. In another approach, modulation estimation rather than known modulation is used as the information for the validation signal for comparison with the target signal despite not knowing the spread pattern of the coding. In yet another approach, a one-way function is used to generate a pseudorandom code to spread a first component of the a first signal below the noise floor. The input to the one-way function is a second component sent at a time later than the time.

Wireless signal validation using an independent wireless data link

A computer apparatus comprising a computer chassis, a baseboard component disposed within the computer chassis and a computer module electronically coupled to the baseboard component is disclosed. A heat sink assembly is attached to the computer module to form a computer module heat sink assembly, wherein the heat sink assembly forms part of an integral exterior structure of the computer chassis. The chassis may comprise a compartment disposed through an exterior surface of the chassis for receiving the computer module heat sink assembly in mated fashion. The computer module heat sink assembly forms a water and air tight seal with the internal compartment of the chassis in mated fashion.
