摘要

在GPS+伽利略方案中，从全球的角度来看，该贡献评估了在用户接收天线上使用更高仰角掩蔽角的情况，同时保持与仅GPS方案中实现的定位性能相当。通过比较考虑PDOP和接收机估计编码延迟抖动的时间和地理拟合的合适统计数据，可以看出，在仅GPS场景下，接收机天线掩蔽角为10°时，在GPS+伽利略星座下，掩蔽角为16.5°时，性能是相等的。这一事实被建议作为一种简单的措施来提高大众市场接收机对外部干扰源和多径的鲁棒性。

Dilution of precision and total interference level on a GPS+Galileo compatible receiver. A global perspective.

In a GPS+Galileo scenario and from a worldwide point of view, this contribution evaluates the use of higher elevation masking angles at the user receiver antenna while keeping positioning performances comparable to those achieved in a GPS-only scenario. By comparing suitable statistical figures of merit that account for time and geographical fitting of scenarios in terms of PDOP and receiver-estimated code delay jitter, it is hereby shown that performance equivalence is observed for a receiver antenna masking angle of 10° in a GPS-only scenario, and for 16.5° in a GPS+Galileo constellation. This fact is proposed to be applied as a simple measure to increase the robustness of mass-market receivers to external interference sources and multipath.
