“…2.1 Beidou-3 system Global navigation satellite system (GNSS) is a ranging and positioning system based on timing measurement. Its accurate timing maintenance and transmission is the foundation for offering highprecision positioning, navigation, and timing (PNT) services [7]. Therefore, each major GNSS system has established its own system time.…”

Beidou-3 (BD3) uses the pseudo range transmission method to calculate the clock difference through the pseudo range. However, due to the influence of electromagnetic interference, the clock difference measurement error is too large, which affects the timing accuracy of the power system. This paper first introduces the principle of Beidou timing service; Secondly, it introduces the clock error calculation method; Finally, combined with the clock difference calculation method, this paper presents an anti-interference clock difference correction method based on Least Mean Square (LMS) filter. According to the principle of LMS filter, the influence of electromagnetic interference on pseudo distance can be eliminated, and the clock difference can be calculated. Then the clock difference can be corrected. The simulation results show that the method is feasible and effective.

“…In autonomous engineered systems, magnetic field information can be useful in a variety of navigation applications, including situations where GPS signals are unavailable or unreliable, and scenarios where other sensory modalities are compromised [1,2,8]. In biological systems, magnetic reception appears to be a sensory modality that, alongside other sensory cues, helps several animals achieve remarkable feats that parallel the goals of engineered systems (e.g.…”

Diverse taxa use Earth’s magnetic field in combination with other sensory modalities to accomplish navigation tasks ranging from local homing to long-distance migration across continents and ocean basins. Several animals have the ability to use the inclination or tilt of magnetic field lines as a component of a magnetic compass sense that can be used to maintain migratory headings. In addition, a few animals are able to distinguish among different inclination angles and, in effect, exploit inclination as a surrogate for latitude. Little is known, however, about the role that magnetic inclination plays in guiding long-distance migrations. In this paper, we use an agent-based modelling approach to investigate whether an artificial agent can successfully execute a series of transequatorial migrations by using sequential measurements of magnetic inclination. The agent was tested with multiple navigation strategies in both present-day and reversed magnetic fields. The findings (i) demonstrate that sequential inclination measurements can enable migrations between the northern and southern hemispheres, and (ii) demonstrate that an inclination-based strategy can tolerate a reversed magnetic field, which could be useful in the development of autonomous engineered systems that must be robust to magnetic field changes. The findings also appear to be consistent with the results of some animal navigation experiments, although whether any animal exploits a strategy of using sequential measurements of inclination remains unknown.

“…These include various military and civilian situations such as when Global Positioning System (GPS) or Global Navigation Satellite System (GNSS) signals are denied or degraded due to tampering (Bailey 2016, Casem 2019, Tucker 2020, underwater, where GNSS signals are not available or degraded (Hidalgo and Bräunl 2015), and even indoor environments where GNSS signals are not available (Storms et al 2010). Magnetic field information can also be used to verify GPS data (Huang et al 2019). In biological systems, magnetoreception appears to be a sensory modality that, alongside other sensory cues, helps various types of animal to navigate and travel across oceans and continents, feats that are required of many terrestrial, aerial, and marine engineered systems (e.g.…”

Certain animal species use the Earth’s magnetic field (i.e. magnetoreception) in conjunction with other sensory modalities to navigate long distances. It is hypothesized that several animals use combinations of magnetic inclination and intensity as unique signatures for localization, enabling migration without a pre-surveyed map. However, it is unknown how animals use magnetic signatures to generate guidance commands, and the extent to which species-specific capabilities and environmental factors affect a given strategy’s efficacy or deterioration. Understanding animal magnetoreception can aid in developing better engineered navigation systems that are less reliant on satellites, which are expensive and can become unreliable or unavailable under a variety of circumstances. Building on previous studies, we implement an agent-based computer simulation that uses two variants of a magnetic signature-based navigation strategy. The strategy can successfully migrate to eight specified goal points in an environment that resembles the northern Atlantic ocean. In particular, one variant reaches all goal points with faster ocean current velocities, while the other variant reaches all goal points with slower ocean current velocities. We also employ dynamic systems tools to examine the stability of the strategy as a proxy for whether it is guaranteed to succeed. The findings demonstrate the efficacy of the strategy and can help in the development of new navigation technologies that are less reliant on satellites and pre-surveyed maps.
