WebApr 1, 2024 · It is the first step performed by a GNSS receiver. The outcome of this process decides if a particular satellite signal is present or not in the received signal, and it also gives a rough... The terminals take a snapshot of the raw GNSS signal and then transmit it to the reference station with its identity data. An LoRa (long range) communication link, a long-range and low-power wireless communication, is used to transmit the information between terminals and the reference station. See more Due to the limitations in terminal communication and computational capacity, the length of GNSS snapshot data is limited to a … See more Because of the lack of the bit and frame synchronization, the code phase, known as the fractional millisecond pseudorange, can be directly obtained. This can cause a problem of integer ambiguity. An algorithm for … See more The main concept of the fine code-phase estimation involves the interpolation or fitting approach. Normally, the shape of the correlation … See more Differential techniques can be classified as absolute and relative positioning. The former requires the reference station to broadcast differential data, which is not sensitive to time synchronization. The latter requires the … See more
