  • Publication number: 20250062892
    Abstract: A method for data processing, a readable medium, and an electronic device are provided. The method for data processing includes: receiving a data processing task; determining target data corresponding to the data processing task and a target first key corresponding to the target data; decrypting the target first key according to the first session key via a target computing node to obtain the first key, and decrypting the target data based on the first key to obtain the data to be processed; and determining a data processing result according to a target model and the data to be processed. The target computing node is executed in a trusted execution environment. The target model is obtained by decrypting an encrypted target model based on a model key, the model key is stored in a key management service, and the key management service is executed in the trusted execution environment.

  • Patent number: 10962651
    Abstract: The invention discloses an ionospheric delay correction method for LEO satellite augmented navigation systems for GNSS. According to the method, GNSS satellite navigation signals received by LEO GNSS receiver loads are used for providing ionospheric information for navigation augmentation for earth surface users. In the method, as a set of mobile navigation augmentation reference stations, LEO satellites continuously observe the global ionosphere to generate ionospheric delay correction information, and the ionospheric delay correction information is sent to the earth surface users to obtain augmented navigation performance.

  • Patent number: 7456782
    Abstract: The present invention provides GPS receivers with clock calibration for fast reacquisition of GPS signals after waking up from a sleep state or coming out of signal blockage. In a preferred embodiment, a GPS receiver comprises a local clock based on an oscillator, e.g., crystal oscillator. The GPS receiver calculates a clock calibration value based on a computed oscillator count for the period during which the GPS receiver is in the sleep state or the signal is blocked. This clock calibration value is used to calibrate the local clock after the GPS receiver wakes up or comes out of signal blockage for fast reacquisition of GPS signals.
