An FFT-based correlation is then performed on each of the possible 2 X bit data-bit combinations of the incoming BeiDou signal with the locally generated T coh ms long data-modulated-PRN-code-cycles ( i.e., the output of Step 4).

Robust fine acquisition algorithm for GPS receiver with limited resources. GPS Solut. 2016, 20, 77–88. [ Google Scholar] [ CrossRef] For a coherent integration period of T coh ms (which is chosen as even), a ((( T coh)/2) × 1000 =) X bit number of data bits is selected first. For example, for a coherent integration period of 4 ms, the number of data bits, X bit = 2. In case of X bit = 2, all possible combinations for incoming data bits will be 2 X bit = 4. Therefore, there will be four possibilities for incoming received data bits, which are: [+1 +1], [+1 −1], [−1 +1], and [+1 +1].

The strategy of the orbit solution is similar to the official 5-system CODE solution for MGEX (Prange et al. 2017), i.e., 3-day orbital arcs are generated, and the solution for a particular day refers to the middle day of the arc. Such an approach greatly stabilizes the solution, especially for new and incomplete GNSS systems, and thus is used not only for MGEX solutions, but also for operational and reprocessed products at CODE (Lutz et al. 2016).

For example, for a coherent integration period of 5 ms, the first 5 bits of NH code, i.e., [−1 −1 −1 −1 −1] can be selected. Also, a long incoming BeiDou signal of ( T coh + 19) ms is required to carry out the FFT-based acquisition. In case of T coh = 5 ms, the acquisition metric will be consisted of 24 ms long incoming signal. Kouba, J.; Mireault, Y. [IGSMAIL-1943] New IGS ERP Format, version 2. 1998.

The RF front-end module is responsible for signal amplification, noise filtering, down-conversion, automatic gain control, and analogue-to-digital conversion. The front-end module converts the received analog data to digital Intermediate Frequency (IF) data at a rate which is several times more than the code chipping rate. A 26 MHz sampling frequency is used to generate the raw digitized IF samples in all the experimented cases of this work.

Accessed 27 May 2019 The Chinese BeiDou Navigation Satellite system (BDS) has a mixed space constellation that will have, when fully deployed, five Geostationary Earth Orbit (GEO) satellites, twenty-seven MEO satellites and three Inclined Geosynchronous Satellite Orbit (IGSO) satellites. The GEO satellites are operating in orbit at an altitude of 35,786 kilometers and positioned at 58.75°E, 80°E, 110.5°E, 140°E and 160°E, respectively. The MEO satellites are operating in orbit at an altitude of 21,528 km and an inclination of 55° to the equatorial plane. The IGSO satellites are operating in orbit at an altitude of 35,786 km and an inclination of 55° to the equatorial plane. These satellites broadcast navigation signals and messages within three frequency bands. The BDS has been in development for more than a decade, and it is estimated to be operational with global coverage at the latest in 2020 [ 1, 2]. The BeiDou satellites transmit ranging signals based on Code Division Multiple Access (CDMA) principle, like GPS and Galileo. The mixed constellation structure of BeiDou results in better observation geometry for positioning and orbit determination compared to current GPS and GLONASS, and future Galileo, especially in China and neighboring regions. The BeiDou system has already started contributing to the multi-GNSS benefits where increased accuracy, availability and integrity are possible when utilizing interoperable GNSS [ 3]. An estimate of the noise power μ N is obtained first by correlating the incoming signal with the locally generated PRN (Pseudo Random Noise) code with a correlator which is +2 chips early from the prompt correlation index.
