Abstract
Disclosed are systems and methods for a computerized Hyper-precise time (HPT) framework that accurately and efficiently provides precise time data for all sorts of network-based and local operations. The disclosed HPT framework can, among other benefits, provide sub-nanosecond time accuracy for operations involving, but not limited to, precise positioning, ambiguity resolution, mitigation of signal delays, maintaining continuous and accurate tracking for dynamic applications, improved convergence for accurate solutions, and the like. The framework can be utilized for Real-Time Kinematic (RTK), such that the determined HPT can directly contribute to achieving the high levels of accuracy and reliability required in RTK applications.

- executing ambiguity resolutions based on the receiver information;
- executing a correction model based on the receiver information and ambiguity resolutions, wherein the execution of the correction model is based on estimated coefficients that are related to the ambiguity resolution of the receiver information;
- generating, on the RTK network, based on the correction modelling, a Virtual Reference Station (VRS);
- and
- determining, based on information related to the VRS, hyper-precise time (HPT) in relation to the receiver, the HPT enabling accurate execution of computer-executable instructions by user equipment (UE).
