Joint pseudo-range and Doppler positioning method with LEO Satellites‘ signals of opportunity
Satellite NavigationLow Earth Orbit (LEO) satellites, with their wide coverage and large number, have gradually become a crucial platform and means for navigation and positioning services. Compared to other LEO constellations, Starlink has over 6000 satellites in orbit, and

Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

Two-way time transfers between NRC/NBS and NRC/USNO via the Hermes (CTS) satellite [PDF]
, 1978 At each station the differences were measured between the local UTC seconds pulse and the remote UTC pulse received by satellite. The difference between the readings, if station delays are assumed to be symmetrical, is two times the difference between ...

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...
