Abstract: A system comprises circuitry configured to: receive a plurality of GNSS signals; determine GNSS measurements based on the GNSS signals; compute a solution for position and clock offset based on the GNSS measurements; place the clock offset of the solution into a moving window time buffer having a time window; perform a curve fit procedure on the clock offset of the solution in the moving window time buffer to obtain a curve fit; compute curve fit residuals by subtracting the curve fit from the clock offset; examine magnitudes of the curve fit residuals over the time window to identify a largest curve fit residual of the curve fit residuals in the time window; determine whether the largest curve fit residual in the time window exceeds a predetermined detection threshold; and determine that spoofing is present when the largest curve fit residual in the time window exceeds the predetermined detection threshold.

Abstract: This disclosure describes systems and methods for providing antenna steering through GNSS jamming, spoofing, and airplane maneuvers. In certain embodiments, a device includes a GNSS antenna configured to receive GNSS signals transmitted from a plurality of GNSS sources; and a GNSS antenna support structure mounted within a vehicle, wherein the GNSS antenna is mounted to the GNSS antenna support structure, wherein the GNSS antenna support structure is configured to keep directionality of the GNSS antenna pointing up during motion of the vehicle.

Abstract: Systems and methods for approach system selection are provided herein. In certain embodiments, a method includes receiving an approach identifier. Further, the method includes identifying a plurality of approach modes associated with the approach identifier. Additionally, the method includes selecting an approach mode in the plurality of approach modes based on an integrity measure of navigation guidance associated with separate approach modes in the plurality of approach modes. Moreover, the method includes providing the navigation guidance for the selected approach mode to an approach system for guiding a vehicle through an approach for the selected approach mode.

Abstract: An online survey platform and process for correlating the bid price offered by a supplier for the completion of an out-of-network survey hosted on the survey platform to one or more intrinsic value indicators of the survey. If the supplier's bid price is less than or equal to the survey budget price set by the buyer, then the routing platform of the present invention will route the supplier's respondent(s) to the survey.

Abstract: Disclosed in some examples is a question platform which matches survey creators with survey takers (entities) referred by publishers. In some examples, the match can happen in real-time or near real time based upon a number of match criteria. Match criteria may include survey creator criteria submitted by the survey creators that describe desired entity attributes, a bid price (e.g., maximum price they are willing to pay), and survey content information. Match criteria may also include publisher criteria that describe entity information, an ask price (minimum price that the publisher is willing to accept for providing access to the entity), and content criteria (e.g., restrictions on the types of survey, the number of questions, and the like).

Abstract: An online survey platform and process for routing respondents who are attempting to take a survey from a mobile device to mobile-friendly surveys, thereby increasing the overall efficiency of the survey platform. A survey platform embodying features of the present invention comprises a plurality of online surveys hosted on the survey platform. When a respondent enters the survey platform for the purpose of taking an online survey, the survey platform will access the respondent's device information and prepare a list of available surveys. The survey platform will then determine whether the survey's mobile conversion delta meets the panel supplier's threshold requirements and, if so, route the respondent to one of the qualified surveys.

Abstract: A system to select a type of satellite from a plurality of types of satellites in a multi-constellation of satellites is provided. The system includes at least a first receiver configured to input signals from a first type of satellite and a second receiver configured to input signals from a second type of satellite and a processor. The processor: executes a multi-constellation-selection software module to associate a current position with a mapping feature and select at least one selected type of satellite from the plurality of types of satellites based on the associated mapping feature; executes a compute-position/velocity/time (PVT) software module to compute a current position/velocity/time based on at least one selected input signal input at a receiver associated with the at least one selected type of satellite; and feeds the computed current position/velocity/time to the multi-constellation-selection software module based on the execution of the compute-PVT software module.

Abstract: Systems and methods may reducing website redirection for surveys. A method may include receiving, at a host server, an indication via an application programming interface (API), the indication including a request for survey. Demographic questions may be supplied and at least one may be answered. The method may include determining whether a respondent to the demographic questions is qualified for a survey, and sending information including a result of the determination.
