Global navigation satellite systems
Global positioning systems first became available for private use in 1995. Since the introduction of NAVSTAR-GPS (Navigation System with Time and Ranging–Global Positioning System) and GLONASS (Globaluaya Navigatsionnaya Sputnikovaya Sistema, Global Navigation Satellite System), such systems have quickly become indispensable in a wide range of applications. Above all, GPS is used today by a lar...
متن کاملDetermining Optimum Modulation for Inter-Satellite Communications Systems
In the small satellite world, it is becoming increasingly popular to use a constellation of small satellites to do the work previously performed by one large satellite. Implicit in this scenario is the requirement for clusters of small satellites to communicate among themselves via an inter-satellite link (ISL). Traditionally, an ISL has taken the form of a time-division-multiple-access (TDMA) ...
متن کاملNoncoherent coded continuous phase modulation
Continuous phase modulation (CPM) systems for noncoherent coded transmission are proposed and analyzed. Specifically, the application of a feedback–free modulator is regarded. For demodulation, a receiver structure which requires only two or three linear filters is considered. For decoding, noncoherent sequence estimation (NSE) with Viterbi decoding and per–survivor processing is applied. Notew...
متن کاملAdaptive Coding and Modulation Techniques for Advanced Satellite Mobile Systems
In this paper, adaptive coding and modulation techniques are envisaged in a satellite mobile system adopting the WCDMA air interface. The physical layer performance, in terms of bit error rate, for several coding rates and modulation formats are reported. Preliminary results of the feasibility for OFDM techniques in the satellite channel are also shown.
متن کاملPhase Compensation Sensor for Ranging Consistency in Inter-Satellite Links of Navigation Constellation
Theperformanceoftheglobalnavigationsatellitesystem(GNSS)canbeenhancedsignificantly by introducing the inter-satellite links (ISL) of a navigation constellation. In particular, the improvement of the position, velocity, and time accuracy, and the realization of autonomous functions require the ISL distance measurement data as the original input. For building a high-performance ISL, the ranging co...
