It is well known that multipath effect remains a dominant error source that affects the positioning accuracy of Global Navigation Satellite System (GNSS) receivers. Significant efforts have been made by researchers and receiver manufacturers to mitigate multipath error in the past decades. Recently, a multipath mitigation technique using dual-polarization antennas has become a research hotspot ...

Multipath remains a significant error source to the GPS user even when employing a receiver and antenna designed for multipath rejection. This study evaluated data processing methods to further remove pseudorange multipath from observations collected by a GPS reference station using multipath-resistant hardware. Both templateand surface-based empirical models were implemented as batch processes...

Multipath routing is generally known for its highly effective performance in applications involving data streaming. However, to date, only a handful of research studies have looked at the performance of multipath routing in WSN systems. Moreover, according to our knowledge, there has been no earlier study on the use of multipath routing in ZigBee WSNs. In this paper, three multipath routing tec...

In urban scenarios, radar returns consist of a direct path return along with multipath returns from signal reflections off surfaces such as building walls or floors. When multipath is resolvable, and given the knowledge of the geometry of the reflecting surfaces, it has recently been demonstrated that multipath returns create additional “virtual” radar sensors, thereby permitting target localiz...

| We motivate and formally deene dynamic multipath routing and present the problem of packet forwarding in the multipath routing context. We demonstrate that for multipath sets that are suux matched, forwarding can be eeciently implemented with (1) a per packet overhead of a small, xed-length path identiier, and (2) router space overhead linear in K, the number of alternate paths between a sour...

Under assumption that the surrounding environment remains unchanged, multipath contamination of GPS measurements can be formulated as a function of the sidereal repeatable geometry of the satellite with respect to the fixed receiver. Hence, multipath error estimation amounts to a regression problem. We present a method for estimating code multipath error of GPS ground fixed stations. By formula...

The concept of multipath invariance asserts that there exist properties and/or regions of the code correlation function that do not change as a function of the multipath amplitude, delay, phase and phase rate. These Multipath Invariant (MPI) points exist at the plateaus of the correlation function. Previous experiments have demonstrated that despite low correlation power, it is possible to impl...

Based on available GPS reference network observations we developed, implemented and tested a procedure to estimate carrier phase multipath corrections. This procedure consists of three steps: detection and localization of multipath affected satellite signals, daily estimations of multipath errors, and combination of these daily estimates to corrections for undifferenced L1 and L2 phase measurem...
