Abstract: A residual position correction for one or more non-geolocational satellites is formed by observing through signal reception, from a known location, orbital attributes. Using the residual position correction, the actual position of one or more non-geolocational satellites is determined. Upon denial of GNSS data, the angle of reception of a signal from one of the non-geolocational satellites and the actual position of the satellite, accounting for tropospheric refracting and antenna azimuth and elevations adjustments, is used to determine the geolocation of the antenna terminal.

Abstract: There is a need to develop new internal balance structures that allow for measurements of aerodynamic interference forces (e.g., powered descent forces) in addition to aerodynamic loads. For example, supersonic retropropulsion (SRP) is a technique involving thrusters in opposition to the oncoming airflow to decelerate an aircraft vehicle while traveling at supersonic speeds. SRP has been identified as a key entry, descent, and landing technology for future Mars missions and for reuse of rocket boosters on Earth. Because of the propellant and oxidizer mass required for the thrusters, currently proposed SRP configurations require a significant increase in performance and efficiency before considered an effective solution. The challenge is that this procedure may cause the air around the spacecraft to become unstable.

Abstract: The present disclosure describes internal force transducer balance system and related methods. One such system includes an internal balance having a cylindrical body extending axially along a longitudinal direction that includes an axial strain measurement component of the internal balance, wherein the axial strain measurement component is configured to measure an axial force applied to the internal balance. Disclosed he systems further includes an integral fluid flow path that continuously extends from the first end to the second end of the balance, wherein the integral fluid flow path is positioned in an interior core of the balance and is routed through the axial strain measurement component of the internal balance. The integral fluid flow path also comprises one or more turns as the integral fluid flow path is routed through the axial strain measurement component of the internal balance.

Abstract: A calibration system and method utilizes acceleration of a mass to generate a force on the mass. An expected value of the force is calculated based on the magnitude and acceleration of the mass. A fixture is utilized to mount the mass to a force balance, and the force balance is calibrated to provide a reading consistent with the expected force determined for a given acceleration. The acceleration can be varied to provide different expected forces, and the force balance can be calibrated for different applied forces. The acceleration may result from linear acceleration of the mass or rotational movement of the mass.

Abstract: Techniques for synchronizing a receiver and transmitter in a wireless communication system address synchronization within the context of a detection formulation and provide synchronization statistics used to declare a synchronization detection. A signal is received from a channel at multiple receiving antennas. The receiver and transmitter are synchronized based on the received signal and a channel model incorporating the multiple receiving antennas. The channel model may also incorporate a resolvable delay spread of the received signal with respect to each receiving antenna. Synchronization may be based on a known component of a received signal and further on a channel model incorporating multiple receiving antennas and an interference signal. The known component may be a cyclic prefix or a pilot sequence as in orthogonal frequency division multiplexing (OFDM).

Abstract: A positioning and calibration system are provided for use in calibrating a single or multi axis sensitive instrument, such as an inclinometer. The positioning system includes a positioner that defines six planes of tangential contact. A mounting region within the six planes is adapted to have an inclinometer coupled thereto. The positioning system also includes means for defining first and second flat surfaces that are approximately perpendicular to one another with the first surface adapted to be oriented relative to a local or induced reference field of interest to the instrument being calibrated, such as a gravitational vector. The positioner is positioned such that one of its six planes tangentially rests on the first flat surface and another of its six planes tangentially contacts the second flat surface. A calibration system is formed when the positioning system is used with a data collector and processor.

Abstract: A single vector calibration system is provided which facilitates the calibration of multi-axis load cells, including wind tunnel force balances. The single vector system provides the capability to calibrate a multi-axis load cell using a single directional load, for example loading solely in the gravitational direction. The system manipulates the load cell in three-dimensional space, while keeping the uni-directional calibration load aligned. The use of a single vector calibration load reduces the set-up time for the multi-axis load combinations needed to generate a complete calibration mathematical model. The system also reduces load application inaccuracies caused by the conventional requirement to generate multiple force vectors. The simplicity of the system reduces calibration time and cost, while simultaneously increasing calibration accuracy.
