Space System “Radiomet” for GLONASS/GPS Navigation Signal Radio Occultation Monitoring of Lower Atmotion satellites passing through lower atmosphere and ionosphere. Authors of the concept – Russian organizations FSUE “RISDE” and IRE RAS..“Radiomet”, in comparison with existing system “Formosat-3” (COSMIC), should provide more than twice higher quantity of atmospheric parameters measurements per da

SEPSAT – A Nanosatellite to Observe Parameters of Space Weatherxtreme Ultraviolet Radiation (EUV), the higher atmosphere and effects of solar fluctuation on parameters of the ionosphere. This helps to improve our knowledge of integrity and accuracy of GNSS signals, the origin and variation of EUV radiation and finally the composition of the solar and upper atmo

Small Satellite Constellations for Measurements of the Near-Earth Space Environmentty that preclude solely independent, localized measurements. In this chapter we discuss some of the factors that must be considered when designing a system for space weather monitoring and the scientific investigation of the near-Earth environment. Some important parameters include: (1) the number f

Satellite Formation for a Next Generation Gravimetry Mission its space/time variations: the effect of the geopotential shows up as a variation of the inter-satellite distance, which is measured by a suitable metrology. Accelerometers are utilized on each satellite for measuring and separating the effect of the non-gravitational forces. Thales Alenia Space It

Relative Trajectory Design for Bistatic SAR Missionsions. Trajectory design process is simplified by using analytical relative motion models that include Earth oblateness perturbations and optimize mission performance. In addition, proposed design reduces trajectory establishment and maintenance efforts. examples are briefly summarized where best rel

Earth Observation Using Japanese/Canadian Formation Flying Nanosatellitesency (JAXA). The main objective of the project is to design, build, launch and operate two 18 kg nearly identical nanosatellites that will be launched as a stack and separated in space to demonstrate the feasibility of Autonomous Formation Flight (AFF) based on aerodynamic differential drag only.

A Bi/Multi-Static Microsatellite SAR ConstellationDMC) and RapidEye. However, such satellites are currently limited to providing useful images over cloud free regions during daylight. Whilst the use of constellations does increase the probability of achieving useful images within short timescales over most regions, there are still areas, such as th
