摘要： The present invention is directed to accurate GPS (global positioning system)-free relative navigation between an unmanned aerial vehicle (UAV) and a tanker aircraft. The UAV transmits a signal which is received by an antenna array at the tanker aircraft. Horizontal relative position of the UAV is determined by calculating range and bearing based on time and phase differences in the received signal. Vertical relative position of the UAV is determined by comparing the altitude of the UAV with the altitude of the tanker aircraft. The tanker aircraft then transmits a navigation solution based on the relative position of the UAV which is received by the UAV. The UAV may utilize the navigation solution transmitted by the tanker aircraft as a backup to a GPS determined navigation solution, in a GPS denied scenario, or in combination with an INS (inertial navigation system) determined navigation solution.

摘要： A system and method of enabling digital beamforming (DBF) for use with RF receiver systems with a multi-element array antenna having short repetitive synchronizaton sequences in a noise and/or jamming environment. The method includes the following steps: a) receiving repetitive synchronization RF signals utilizing a multi-element array antenna, each of the repetitive synchronization RF signals includes an ideal known synchronization sequence, the ideal known synchronization sequence is denoted as yd and a length of the ideal known synchronization sequence is denoted as Nd; b) calculating a sequence of magnitudes and phases for each element of the multi-element array antenna corresponding to each of the ideal known synchronization sequences in the received synchronization RF signals, the sequence of the magnitudes and the phases comprises an array of N elements and is denoted as x, wherein the phases are also referred to as absolute phases; c) calculating a relative phase for each element in the sequence of the magnitudes and the absolute phases by referencing the absolute phases of all elements in the array x of N elements to a phase of a single element in the array x of N elements; d) converting the array x of N elements with the magnitudes and the absolute phases into an array of N elements with the magnitudes and the relative phases by replacing each of the absolute phases in the array x of N elements with the calculated relative phase for each element, the array of N elements with the magnitudes and the relative phases is denoted as xr; e) calculating a relative cross correlation vector for each element of the multi-element array antenna utilizing xr and yd, the relative cross correlation vector is denoted as rxd, where rxd=E{xryd*} and * is a complex conjugate; and, f) generating a relative cross correlation vector estimate by filtering rxd, for use with DBF techniques.

摘要： The present invention is directed to a small size and light weight small form factor user system suitable for having TTNT connectivity which consumes minimum power to operate. The small form factor user system having TTNT connectivity may be capable of interacting in a low latency real time manner with airborne networks. The small form factor user system having TTNT connectivity may have significantly reduced radio power consumption and form factor size through maintaining core capabilities of the full size TTNT terminal while relaxing other capabilities. An encapsulated message structure may be utilized to simplify communication between the TTNT small form factor user system and the full size TTNT nodes.

摘要： A method of receiving a plurality of simultaneously transmitted data streams is disclosed. Each data stream is divided into portions and transmitted at predetermined frequencies and times according to a frequency-hopping pattern. The portions are received using a plurality of receivers. Each receiver is configured to receive portions transmitted on one of the predetermined frequencies. The received portions are temporarily stored in a memory such that the received portions are stored as a function of receiver and time. The stored portions are compared to the frequency-hopping pattern. It is determined if any combination of the stored portions corresponds to the predetermined frequencies and times of the frequency-hopping pattern.

摘要： Disclosed are a system and method for controlling transmit power of a mobile node in air-to-ground communications to a fixed node. Power is controlled by taking into consideration the position of the mobile node, the ground position of a plurality of fixed nodes, and the RF pattern of an antenna. Preferably, a power level is selected that will excite the fewest number of the plurality of fixed nodes while still maintaining a stable connection with at least one of the fixed nodes. The system may also utilize a repeater to receive communication signals from one or more mobile phones. This repeater then pre-amplifies the signal with a gain control signal received from one of the plurality of fixed nodes. The repeater would then pass the pre-amplified signal to the power amplifier for further amplification as controlled by the power controller.
