本文讨论了全球卫星导航系统（GNSS）接收机直接位置估计（DPE）的理论和实践问题。DPE是一种替代现有定位方法的方法，在这种方法中，对可见卫星的时间延迟和多普勒频移进行估计，以解决计算接收机位置的几何问题。相比之下，DPE直接从采样数据中推断位置，而不需要中间步骤。从理论上和实验上看，这种方法大大提高了接收机的精度和可靠性。
This article discusses theoretical and practical aspects of direct position estimation (DPE) of global navigation satellite system (GNSS) receivers. DPE is an alternative approach to the well- established positioning method, where time delays and Doppler shifts to the visible satellites are estimated to solve for a geometrical problem to compute the receiver's position. In contrast, DPE infers position directly from the sampled data without intermediate steps. This approach has been seen, both theoretically and experimentally, to substantially increase the receiver's accuracy and reliability.
