A method of detecting and mitigating Global Navigation Satellite System (GNSS) spoofing events may comprise determining a first vehicle state based on an Inertial Navigation System (INS) without GNSS input, determining a second vehicle state based on an INS with GNSS input, and comparing the first vehicle states. When a difference between the vehicle states exceeds a predetermined threshold, the method concludes that GNSS spoofing is present, and utilizes only the first vehicle state as a correct vehicle state. The method may further implement at least one state processing path, comprising consecutive processing runs based on INS sensors. The method may further comprise reevaluating the vehicle state processing path, when the difference between the first vehicle state and the second vehicle state exceeds a threshold, to extricate a GNSS component from the processing path to at least a predetermined amount of time prior to when the GNSS spoofing was detected.

Systems and methods are disclosed for delivering programming content to vehicles (e.g., seagoing vessels) in a cost-effective manner. In some embodiments, programming content may be delivered to vehicles over previously deployed networks (e.g., satellite networks), using excess network capacity which may not otherwise be used to deliver data. By opportunistically employing excess network capacity (e.g., as the capacity becomes available), data constituting programming content may be delivered to vehicles over a period of time, such as via multicast transmission. A vehicle may store received data on one or more onboard servers. After an item of programming content has been received, the item may be made accessible to the vehicle's crew and/or passengers, such as by streaming the item to one or more suitably configured playback devices. Content may be served to playback devices 'on demand' and/or according to a programming schedule.

The present invention provides an improved antenna system on moving platform that is in communication with multiple satellites for simultaneous reception and transmission of RF energy at multiple frequencies. The antenna is implemented as a multi-beam, multi-band antenna having a main reflector with multiple feed horns and a sub-reflector having a reflective surface defining an image focus for a Ka band frequency signal and a prime focus for a Ku band frequency signal.

A printer for printing a viscous material at predetermined positions forming a pattern on a substrate. The printer includes a frame, a device, mounted to the frame, having a number of perforations arranged to form the pattern, a support apparatus, coupled to the frame, that supports the substrate in a printing position beneath the device, and a material dispenser. The material dispenser has a chamber to contain the viscous material to be printed on the substrate. The chamber has an opening through which the viscous material is dispensed. The material dispenser is coupled to the frame, positioned over the device, and constructed and arranged to dispense the viscous material through the perforations in the device and onto the substrate. The material dispenser has a retraction device that prevents leakage of the viscous material from the opening after dispensing is complete.

An apparatus for depositing a selected pattern of solder onto a substrate comprising a substrate support, a solder ejector, and an orifice defining structure. The substrate support has structure for bearing a substrate on which one or more electronic components are to be mounted. The solder ejector has a housing that defines a cavity for containing molten solder. The orifice defining structure includes a flat disk having an orifice defined therethrough for producing a stream of molten solder and a disk support structure that supports the disk around the orifice and is replaceably coupled to the cavity-defining structure. Also disclosed is an apparatus that deposits a selected pattern of solder onto a substrate and includes a substrate support, a solder ejector that directs solder droplets to desired positions on the support, and an ejector aligner that adjusts the orientation of the solder ejector in two angular dimensions to enable adjustment of the trajectory of the stream of molten solder droplets.

Jet soldering system and method

Depositing a selected pattern of solder droplets onto a substrate on which one or more electronic components are to be mounted, the substrate being mounted on a substrate support and moved relative to a solder ejector along a scan axis, the droplets being deflected along a fan axis that is transverse to the scan axis by selectively applying a charge and passing the charged droplets through an electric field.

A printer for printing a viscous material at predetermined positions forming a pattern on a substrate. The printer includes a frame, a device having a number of perforations arranged to form the pattern, a support apparatus that supports the substrate in a printing position, and a material dispenser having a substantially cylindrical chamber to contain the viscous material. The chamber has an opening through which the material is dispensed. The material dispenser is positioned over the device and constructed and arranged to dispense the viscous material through the perforations in the device onto the substrate. In embodiments of the present invention, the material dispenser is adapted to receive standard cartridges containing the viscous material, and the printer further includes a pressurized air source for forcing the viscous material from the cartridges into the material dispenser and from the material dispenser through the perforations on the device and onto the substrate.

An apparatus for depositing a selected pattern of solder onto a substrate comprising a substrate support, a solder ejector, and a gas-delivery system associated with the solder ejector. The substrate support has structure for bearing a substrate on which one or more electronic components are to be mounted. The solder ejector has a housing that defines an orifice for producing a stream of molten solder droplets along a selected trajectory relative to the substrate support to deposit molten solder onto the substrate in a selected pattern. The gas delivery system has an input for receiving pressurized inert gas and an output aligned with the directed stream of molten droplets for discharging from the orifice of the solder ejector a flow of inert gas aligned with the ejected molten solder droplets. A method for depositing a selected pattern of solder onto a substrate is also described.
