Most systems reliant on advanced technology present a familiar dilemma: the system designer does not know what the customer wants, while the customer does not understand the technology well enough to know what is possible. Although Earth observation satellite systems ought ideally to be designed for all customer needs, this is impossible for several reasons. Not least of these is the difficulty of identifying at the outset all, or even most, of the possible customers. This circumstance makes the creation of Earth observation systems somewhat speculative and imposes particular constraints on the subsystems for processing and use of the data. This paper discusses the technical and institutional aspects of processing and dissemination of data from remote-sensing satellites for the benefit of the user.

Definition Of

Presently, the Earth Observation community is demanding applications that provide low latency and high downlink capabilities. An increase in downlink contacts becomes essential to meet these new requirements. The Federated Satellite Systems concept addresses this demand by promoting satellite collaborations to share unused downlink opportunities. These collaborations are established opportunistically and temporarily, posing multiple technology challenges to be implemented in-orbit. This work contributes to the definition of the Federation Deployment Control Protocol which formalizes a mechanism to fairly establish and manage these collaborations by employing a negotiation process between the satellites. Moreover, this manuscript presents the results of a validation campaign of this protocol with three stratospheric balloons. In summary, more than 27 federations with 63.0% of throughput were established during the field campaign. Some of these federations were used to download data to the ground, and others were established to balance data storage between balloons. These federations allowed also the extension of the coverage of a ground station with a federation that relayed data through a balloon, and the achievement of a hybrid scenario with one balloon forwarding data from a ground device. The results demonstrate that the proposed protocol is functional and ready to be embedded in a CubeSat mission.

The inflight stability of the earth observation satellite is a significant factor having an influence on the geometric performance of its imagery. The estimation of the attitude perturbance is therefore indispensable to spaceborne photogrammetry application. In this paper, an experiment using a short strip of multispectral images obtained from ZY-3 satellite is conducted. The detection method for attitude perturbance based on parallax observation is adopted, while a novel approach of estimating the attitude perturbance angles from the perturbance caused image displacements is also proposed and demonstrated. The estimated results indicate that the ZY-3 satellite was affected by considerable perturbances with distinctive frequencies during the flight of the investigated images, and attitude perturbances hava also undermined the geometric performance of the acquired imagery.

The results of modeling the thermal operation of solar panels (PSB) of the Earth observation satellite (EOS) when moving in a circular orbit are presented. Modeling of the thermal regime is carried out for two groups of photovoltaic converters (FEP). FEPs are conventionally divided into groups, depending on the strength of the influence of different heat fluxes characteristic of the movement of the satellite in a circular orbit. Analytical expressions for the heat balance equation of the PSBs and the results of numerical calculations at the end of the active life (SAC) are given. In this work, methods of deduction, induction, analysis, modeling, formalization, experiment, as well as statistical method, system and structural-functional method were used. The presented model for calculating the temperature of the solar panel of the Earth observation satellite is a set of mathematical expressions that allow calculating temperature of any FEP within a particular solar panel and make adjustments to the plan of exploitation.

Synchronous Orbit

When Earth observation satellite systems are designed, one typically prefers a sun-synchronous orbit. However, the first generations of cubesats from Planet were deployed out of the International Space Station (ISS) and therefore do not obey such an orbit. Their configuration samples at different local times within the mid-latitudes. Consequently, it is in theory possible to exploit photometric techniques and extract highly detailed topographic information. In this study we demonstrate and explore photometry based on Planet cubesat images for Tyndall glacier at the Southern Patagonian icefield, and Zhadang glacier situated on the Tibetan plateau.
