“…Furthermore, in an any-to-any-each satellite tracks all other satellites in the constellation within one scheduling period-inter-satellite link scenario a continuous calibration of the space segment is achievable. The inter-satellite link terminals on a satellite have the capability to point to each other for calibration (Koepf et al 2002).…”

In this simulation study we analyze the benefit of ground-space optical two-way links (OTWL) for Galileo precise orbit determination (POD). OTWL is a concept based on continuous wave laser ranging and time transfer with modulated signals from and to ground stations. The measurements are in addition to Global Navigation Satellite System (GNSS) observations. We simulate the measurements with regard to 16 Galileo Sensor Stations. In the simulation study we assume that the whole Galileo satellite constellation is equipped with terminals for OTWL. Using OTWL together with Galileo L-band, in comparison with an orbit solution calculated with L-band-only, demonstrates the advantage of combining two ranging techniques with different influences of systematic errors. The two-way link allows a station and satellite clock synchronization. Furthermore, we compare the ground-space concept with the satellite-to-satellite counterpart known as optical two-way inter-satellite links (OISL). The advantage of OTWL is the connection between the satellite system and the solid Earth as well as the possibility to synchronize the satellite clocks and the ground station clocks. The full network, using all three observation types in combination is simulated as well. The possibility to estimate additional solar radiation pressure (SRP) parameters within these combinations is a clear benefit of these additional links. We paid great attention to simulate systematic effects of all observation techniques as realistically as possible. For L-band these are measurement noise, tropospheric delays, phase center variation of receiver and transmitter antennas, constant and variable biases as well as multipath. For optical links we simulated colored and distance-dependent noise, offsets due to the link repeatability and offsets related to the equipment calibration quality. In addition, we added a troposphere error for the OTWL measurements. We discuss the influence on the formal orbit uncertainties and the effects of the systematic errors. Restrictions due to weather conditions are addressed as well. OTWL is synergetic with the other measurement techniques like OISL and can be used for data transfer and communication, respectively.

“…To increase the data rate by orders of magnitude, optical communications methods are required. The transmission of data via laser has been a long-standing goal in the development of planetary communications technology [101]. Transmission rates hundreds, or thousands, of times greater than currently achievable from Mars orbit could be possible using smaller, lower mass devices, if the many challenges facing laser communications can be overcome.…”

Obtaining detailed information from solar system exploration missions requires the use of reliable, high-performance communications systems. Planetary landers and orbiters experience a wide variety of challenges, which complicate the design of communications architecture, and which affect the ability of the spacecraft to transmit significant quantities of data back to Earth. Aside from the large distances involved, the spacecraft environment dominates the design and capability of the communications system. As missions become more ambitious in the quantity of data to be generated and the types of environment to be explored, new technologies and techniques are required to meet these communication needs. This article reviews some of the major challenges facing the next generation of solar system missions, and outlines some of the solutions which have been proposed to address them.

“…The data can be sent in IsOWC systems at the speed of light without much delay and with minimum attenuation since the space is considered to be a vacuum [8]. The advantage of using optical link over radio frequency (RF) links are [9]: 1)High speed, small size of payload 2)No utilization tariffs 3)Highly secure connectivity.…”

Abstract:The aim of this paper is to design an Inter Satellite Optical Wireless Communication System (IsOWC) and find the relationship between various performance parameters. The development of OWC system are beneficial for communication in terms of providing higher bandwidth, small size, light weight, low cost. The IsOWC system can provide better performance as compare to presently used microwave satellite system. This paper give complete analysis of Intersatellite link (ISL) by varying various performance parameters such as BER, Transmitted power, Link distance etc. In this paper IsOWC system are modified and simulation results shows a good enhanced value of Quality factor and Bit error rate. This simulation is done by using a Optisystem (14.0) software.
