In recent years, we have observed steady progress in signals, services, and satellite deployment of Global Navigation Satellite Systems (GNSS). Consequently, modernizing and developing GNSS constellations have moved us towards an era of multi-constellation and multi-frequency GNSS signal availability. Also, the deployment of LEO constellations brings opportunities for LEO-augmented PNT services and applications, which, however, forces revisiting the existing and developing novel processing algorithms when fusing LEO and GNSS. Meanwhile, the technology development provided high-grade GNSS user receivers to collect high-rate, low-noise, and multipath impact measurements. Also, recent extraordinary progress in low-cost GNSS chipsets, smartphones, and sensor fusion must be acknowledged. Such advancements boost GNSS research and catalyze an expansion of satellite navigation to novel areas of science and industry. On one side, the developments stimulate a broad range of new GNSS applications. On the other side, they result in new challenges in data processing. Hence, algorithmic advancements are needed to address the opportunities and challenges in enhancing high-precision GNSS applications' accuracy, availability, interoperability, and integrity.
