Precise Point Positioning (PPP) is relatively modern GNSS positioning technique that proved its efficiency comparing with traditional Differential for more than three decades. PPP requires only one receiver collecting observations at unknown station, while two receivers simultaneously known-position station and the other station. Extensive mitigation of different errors essential PPP-collected ...

Técnicas de transientes de corrente potenciostáticos foram empregadas no estudo de processos de eletroredução de camadas superficiais formadas no cobalto policristalino em soluções contendo íons carbonato-bicarbonato. As análises dinâmicas do sistema, realizadas através de procedimentos de investigação paramétrica e de rotinas de ajuste não-lineares, demonstraram que os da dos obtidos sob numa ...

Abstract In passive radar and joint communication sensing (JCRS), target with the multiuser multiple input output orthogonal frequency division multiplexing (MU‐MIMO‐OFDM) modulation signal is gaining increasing interest. Multiple transmit nodes emitting MU‐MIMO‐OFDM signals at same carrier one receiver collecting target‐reflected for location velocity estimation are considered. This a typical ...

The positional accuracy of Global Positioning System (GPS) is affected by several errors, the most predominant error being the ionospheric delay. This delay is proportional to the total electron content (TEC). The dual frequency GPS observables can be used to estimate the TEC. The line-of-sight TEC estimated from dual frequency GPS data is corrupted by the instrumental biases of the GPS satelli...

We study experimentally the synchronization dynamics of two semiconductor lasers coupled unidirectionally via two different delayed paths. The emitter laser operates in a chaotic regime characterized by low-frequency fluctuations due to optical feedback and induces a synchronized dynamical activity in the receiver laser, which operates in the continuous-wave regime when uncoupled. Different del...
