Highlights The feasibility of using an S-band GNSS carrier is investigated. The transmission performance, EIRP, and multipath are addressed. The receiving performance, including Doppler and compatibility, is also studied.
Abstract Global navigation satellite systems (GNSSs) play an important role in both military and civilian industries, but most of the existing GNSS carriers are crowded in the L band. Although some modulations, such as binary-offset-carrier (BOC) and its modifications, can reduce the mutual interference of one GNSS signal to others, the exhausted L-band frequencies are still the bottleneck to improve GNSS performance further. The problem can be solved if the GNSS carriers can be allocated to other bands, such as S band (2483.5–2500 MHz) and C band (5010–5030 MHz), which adjoin L band. In this paper, the feasibility of using an S-band GNSS carrier is evaluated systematically. The transmission path loss, the transmission errors, and the signal reception performance of an S-band carrier are analyzed by comparison with an existing L-band carrier and a potential C-band one. The impacts of the S-band carrier both on the satellite payload and on the receiver are discussed. The compatibility of the S-band signal with the existing signals in the adjacent band is also addressed. The conclusive remarks presented will be helpful to implement an S-band carrier.
