1. This article discusses a new integrity monitoring scheme for undifferenced and uncombined multi-frequency multi-constellation PPP-RTK.
2. The proposed scheme uses advanced receiver autonomous integrity monitoring (ARAIM) to compute protection levels (PLs) to indicate the maximum threshold of positioning error based on a pre-defined probability of hazardous misleading information (PHMI).
3. The proposed scheme also takes into account potential faults in regional atmospheric corrections, which may affect many satellites simultaneously.
This article presents a new integrity monitoring scheme for undifferenced and uncombined multi-frequency multi-constellation PPP-RTK. The proposed scheme uses advanced receiver autonomous integrity monitoring (ARAIM) to compute protection levels (PLs) to indicate the maximum threshold of positioning error based on a pre-defined probability of hazardous misleading information (PHMI). The article is well written and provides an overview of the proposed scheme as well as its advantages over existing methods.
The article does not provide any evidence or data to support its claims, which could be seen as a potential bias in the reporting. Additionally, the article does not explore any counterarguments or present both sides equally, which could lead to one-sided reporting. Furthermore, there is no mention of possible risks associated with using this method, which should be noted in order for readers to make an informed decision about whether or not they should use it.
In conclusion, while this article provides an overview of the proposed integrity monitoring scheme for undifferenced and uncombined multi-frequency multi-constellation PPP-RTK, it lacks evidence and data to support its claims as well as fails to explore counterarguments or present both sides equally. Additionally, there is no mention of possible risks associated with using this method, which should be noted in order for readers to make an informed decision about whether or not they should use it.
