Some of the parameters that are considered to measure GNSS antenna performance are polarization, polarization, bandwidth, return loss and antenna dimensions. This study aims to design a low profile dual band microstrip antenna using the Defected Ground System (DGS) and Menader Line (ML) techniques for GNSS applications. In this research, the DGS technique is used to increase the bandwidth while the ML technique is used to reduce the antenna dimensions. This antenna design uses a FR4 Epoxy substrate with a thickness of 1.6 mm. To design and analyze the antenna, the CST Studio Suite 2016 simulator is used. The simulator is equipped with an optimizer feature that can optimize antenna parameters. Based on the design results, an antenna with a size of 183.6 x 183.6 x 1.6 mm3 has been produced. The antenna works in dual band, namely in the band 1247 - 1294 MHz (bandwidth - 3.70% BW) for radio navigation satellite services Glonass (G2) and Galileo (E6). And in the band 1539-1606 MHz (4.26% BW) for the Galileo (E1) flight radio navigation service, Compass and GPS (L1). Keywords: Global Navigation Satellite System (GNSS), low-profile dual-band microstrip antenna, Defected Ground System (DGS) dan Meander Line (ML).

A compact dual-band circularly polarized antenna with wide half-power beamwidths (HPBWs) for compass navigation satellite system applications is proposed in this paper. The CP radiation is realized by arranging four compact dual-band inverted-F monopoles symmetrically to the center point, where the four monopoles are excited with a 90° phase offset through a compact sequential-phase feeding network. The compactness of the dual-band inverted-F monopole is realized by inserting two chip inductors in the horizontal portion of the monopole. The overall dimension of the antenna is only 0.211λ0 × 0.211λ0 × 0.057λ0, where λ0 is the corresponding free-space wavelength at 1.268 GHz. Experimental results show that the proposed antenna exhibits two overlapped impedance and axial ratio bandwidths of 50 MHz (1.236–1.286 GHz) and 40 MHz (1.532–1.572 GHz). Wide HPBWs of about 120°/125° and 121°/116° (XOZ/YOZ planes) at center frequencies (1.268, 1.561 GHz) of the CNSS-2 B3 and B1 bands are obtained, respectively. With these good performances, the antenna can be a good candidate for CNSS applications.

The Inertial Navigation System (INS) is often fused with the Global Navigation Satellite System (GNSS) to provide more robust and superior navigation service, especially in degraded signal environments. Compared with loosely and tightly coupled architectures, the Deep Integration (DI) architecture has better tracking and positioning performance. Information is shared among channels, and the assistant information from INS helps to reduce the dynamic stress of tracking loops. However, this vector tracking architecture may result in easy propagation of errors among tracking channels. To solve this problem, a Fault Detection and Exclusion (FDE) method for the deeply integrated BeiDou Navigation Satellite System (BDS)/INS navigation system is proposed in this paper. This method utilizes pre-filters’ outputs and integration filter’s estimations to form test statistics. These statistics can help to detect and exclude both step errors and Slowly Growing Errors (SGEs) correctly. The monitoring capability of the method was verified by a simulation which was based on a software receiver. The simulation results show that the proposed FDE method works effectively. Additionally, the method is convenient to be implemented in real-time applications because of its simplicity.
