The application of strap-down inertial navigation system/long baseline system (SINS/LBL) has been proven to be an effective method solve the accumulated position error autonomous underwater vehicles (AUVs). However, height positioning in SINS/LBL is generally unstable. Acoustic differential technology uses single- or double-difference mode weaken influence errors on signal propagation time, but vertical result this Moreover, accumulative will cause diverge over time. In view situation that...
Crowdsourcing outsources work to a community of people voluntarily contribute their time finish tasks which were done by employees. The advantages crowdsourcing are low-cost production, the synchronization resources, improved production efficiency and catering customers' demand. Current schemes face many challenges. One problem is that highlighting match interest keywords with workers but less consideration on capability. As result, quality sacrificed. Another challenge how protect privacy...
Abstract Ionospheric delay is one of the major error sources in global navigation satellite system (GNSS) single point positioning (SPP). Some empirical models have been proposed to correct ionospheric delay, which, however, are limited by low accuracy. The single-point time-series-based total electron content (TEC) forecast method theoretically introduces model and accumulation increases during a day. Therefore, based on regular variation characteristics ionosphere, improve accuracy we...
