Demonstration of a time scale with the 87Sr optical lattice clock at NTSC
AIP Advances, 2023 Optical clocks have been applied to the generation of time scales since they provide superb uncertainty and instability in recent years. This paper presents the simulations about the impact of the optical clock’s operational strategies on the performance

GNSS rapid precise point positioning enhanced by low Earth orbit satellites
Satellite Navigation, 2023 The Low Earth Orbit (LEO) satellites can be used to effectively speed up Precise Point Positioning (PPP) convergence. In this study, 180 LEO satellites with a global distribution are simulated to evaluate their contribution to the PPP convergence.

Philosophy of Science, 2021 Programs in quantum gravity often claim that time emerges from fundamentally timeless physics. In the semiclassical time program, time arises only after approximations are taken. Here we ask what justifies taking these approximations and show that time seems to sneak in when answering this question.

Efforts towards a low-temperature-sensitive physics package for vapor cell atomic clocks
Satellite Navigation, 2020 Strong environmental dependence is an intractable problem for vapor cell clocks, for which the high-temperature sensitivity of the physics package is considered one of the dominant reasons.
